Non-Automatic Transfer Switches- RTS Series

,

Russelectric RTS Series non-automatic transfer switches are ideal for applications in which immediate restoration of service (after loss of the normal source) is not critical, and local operations personnel are available to initiate transfer. These switches are UL-listed double-throw devices with identical withstand ratings and design characteristics to RTS Series automatic transfer switches.

Since these non-automatic switches are identical in design to Russelectric RTS Series automatic transfer switches and are of the same exceptional quality, users can be con dent that they are time- tested, reliable, and safe.

Operations personnel can initiate a source transfer locally using electrically operated push-buttons or a mechanical external manual operator, or remotely (optional).

All non-automatic switches can be easily converted to fully automatic operation with the addition of a control panel and minor wiring changes. This ensures flexibility for future expansion and system redesign.

Tested, Listed, and Labeled by UL under UL-1008

Before Underwriters’ Laboratories, Inc. will allow a transfer switch to be listed with a short circuit rating, it requires that the switch be able to close in on the same amount of fault current as it can withstand. All Russelectric RTS Series transfer switches have been fully tested, listed, and labeled for 30-cycle and 3-cycle closing and withstand ratings under UL-1008.

In applications where extremely high short circuit current is available, fuse protection is mandatory. When coordinated with current limiting fuses, Russelectric RTS Series transfer switches have UL-listed closing and withstand ratings of 200,000 A.

Haley VA Hospital

,

Standby Power System at Florida VA Hospital Covers All Electrical Loads

Few if any hospitals have a better power system than the James A. Haley Veterans’ Hospital in Tampa, Florida, thanks to its recently renovated power plant.  Completed at a cost of $47 million, it includes SCADA and a backup system capable of covering all electrical loads for 120 hours (without refueling) in the event of an outage.

A teaching hospital affiliated with the adjacent University of South Florida College of Medicine, Haley Hospital provides a full range of patient services with state-of-the-art technology and research.  It has 548 beds, plus another 118 beds in an on-site long-term care and rehabilitation facility — the Haley’s Cove Community Living Center.  The busiest of four U.S. Veterans Administration (VA) polytrauma facilities in the nation, Haley serves a four-county area in which it also runs four outpatient clinics.

After Hurricane Katrina hit New Orleans in 2005, the VA called for bids to upgrade emergency/backup power systems at VA hospitals in hurricane zones — upgrades that could ensure continuous air conditioning, not just the operation of life-safety and other critical equipment.

For Haley Hospital, the winning bid for power control switchgear, transfer switches, and SCADA was from Russelectric®, based in Hingham, Massachusetts.  Russelectric® designs, builds, commissions, and services on-site power control systems for hospitals, data centers, Internet service providers, airports, and other mission-critical facilities.  Systems can provide sophisticated control functions such as emergency/standby power, peak shaving, load curtailment, utility paralleling, cogeneration, and prime power.  All Russelectric® systems are supported by the company’s factory-direct, 24-hour field service.

Extra Layer of Confidence

The hospital’s administration is pleased with the new power system, which provides many more capabilities than the previous system.  Although there has not been an unexpected utility outage since the system became fully operational in May 2010, Byron Taylor, the hospital’s Lead Power Plant Operator, appreciates the extra layer of confidence.  At Taylor’s side to oversee the system, as they were throughout the planning and installation process, are Engine Technician Kyle Graley and Electrical Shop Supervisor Bill Hagen.

“We’ve had some storms come through, and it has been really nice because we do not have to worry,” says Taylor.  “One time, we saw the storms coming and TECO [Tampa Electric Company] asked us to drop off the grid.  We fired up our generators, and we operated on our own power for 17 hours, while TECO concentrated on restoring power to its residential customers.  That sort of thing has happened several other times for shorter periods, and there has never been a problem.”

Hagen particularly appreciates the quality of the power from the backup system.  “We get more blips from TECO than we do from our system,” he quips.  “It is exceptionally smooth.”

The hospital’s former backup power system included nine on-site generators, yet it could only cover life-safety loads — 45% of the hospital’s total load — in the event of a utility outage.  Hagen has no fond memories for the old system, which he calls “a major headache,” least of all for the system’s dynamic matrix control.  “We had nothing but problems with it,” he recalls.  “We never got it to work in parallel.  It couldn’t even generate a monthly testing report.”

In contrast, the new backup system covers everything — every load for nine buildings, 15 trailers that make up an on-campus clinic, and a parking garage — with just seven new 13,200-VAC Caterpillar diesel generators.  Supplied by Ring Power, the generators produce 2,200 kW each.

Another improvement is the hospital’s renovated fuel system.  The former system had a capacity of 22,000 gallons, and the storage tanks were spread out over several locations.  Today, a new tank farm has four 12,000-gallon tanks.  With another 6,000-gallon tank under each generator, the system has a capacity of 90,000 gallons.

Still more improvements are in the works.  As of now, Haley Hospital receives no rebates or preferred rates from Tampa Electric Company, and the agreement between the entities does not allow the hospital to feed power back to the grid.  But that agreement could change someday.  On the roof of a parking garage, the hospital will be installing photovoltaic cells expected to generate another 500 kW of power.  Newly installed solar panels in the adjacent parking lot near the long-term care facility (Haley’s Cove) will supplement that building’s utility feed by up to 500 kW, so the new cells will boost Haley’s photoelectric output to a total of 1 MW, enough to illuminate two parking lots.  Although feeds from the solar panels are lost when the hospital’s generators take over, under everyday conditions the new panels might provide surplus power that would enable the hospital to sell some power back to TECO.  A peak-shaving arrangement with the utility is also likely in the near future, according to Taylor.

The Power of Information

Also very important to the power control system upgrade is the new state-of-the-art Russelectric® SCADA system, which includes software and screen displays that Russelectric® customized for the hospital’s needs.  It provides interactive monitoring, real-time and historical trending, distributed networking, alarm management, and comprehensive reports around the clock for every detail of the entire power system, not just for the backup components.

In addition to monitoring power quality, the SCADA system’s many functions include continuous monitoring of fuel consumption by each generator and the level of fuel in every tank.  With Russelectric® SCADA, an operator can easily monitor and control a facility’s entire power system using full-color “point and click” interactive computer-screen displays at the system console.  For example, the operator can access and change the system’s PLC setpoints, display any of the analog or digital readouts on switchgear front panels, run a system test, or view the alarm history.  A dynamic one-line diagram display uses color to indicate the status of the entire power system, including the positions of all power switching devices.  Operating parameters are displayed and updated in real time; flashing lights on the switchgear annunciator panel also flash on the SCADA screen.  Event logging, alarm locking, and help screens are standard.

“The SCADA is so sensitive that it detects and explains even the slightest anomaly, including those in the utility feed,” says Taylor.  “A number of times we’ve called TECO because we saw something happening, and they had no idea they even had a problem yet!  The stuff the system does is phenomenal.  It gives us more data than we ever need for an average day, but it’s tremendous that we have it when we do need it.”

Freedom to Test the System

In accordance with state and federal regulations, the backup generators are tested every month.  Thanks to the new system’s capability for closed-transition transfer, the tests inconvenience no one.  Because there is no interference with hospital loads, there is no “blip” (power interruption).

The system gives Taylor and Graley the luxury of carrying out the tests in two different ways.  They can parallel the output of all seven generators to the utility feed, or they can test one generator at a time, up to its full output, by way of a special 2-MW load bank that has an independent control panel.  Testing can be initiated manually or through SCADA.

“It’s so much easier now,” says Hagen.  “We’ll never again have to pay a testing firm to come out and test an engine to make sure it meets all the requirements.”

Unlike most hospitals, Haley has the luxury of four utility feeds.  On a normal day, it draws from two of these (primary) feeds.  This means that, except for testing, Haley does not have to start its generators until it loses three or more utility feeds.
With advance notice from the utility that an outage is likely, Haley’s power plant personnel can now parallel the utility feeds with their own generators, then switch to on-site power seamlessly (closed-transition transfer).  But if there is an unexpected outage (and when the automatic transfer switches are tested), there will be a “blip” of 1 to 10 seconds, depending on the load.  For life-safety and other critical loads, the “blip” is only 1 to 3 seconds.  “Blips” for other loads are adjustable; most are set for 8-10 seconds.

Technical Support

Taylor and Hagen have high praise for Russelectric®’s field support services.  They recall working hand-in-hand with Jim Bourgoin, Russelectric®’s local Field Service Engineer, for seven months.

“During installation, Jim helped the contractors interpret the design whenever they were puzzled,” Hagen says.  “Afterwards, he stuck around to help us get things up and running.  It took a lot just to understand everything this system can do.  I already had a background in this, but it took quite a bit of training to really get up to speed.”

Taylor recalls, “There has not been one time when I have called Jim for an alarm or with questions about the system — whether at midnight or later — that he didn’t answer the phone and help me.  And on two occasions, he drove here at 3 or 4 in the morning to correct something that had gone wrong.  But it’s not just his responsiveness that’s impressed us.  The service he provides is exceptional, and it has been that way since day one.  To me, that’s worth just as much as the system itself.”

Taylor adds that Tom Crider, the local Russelectric® sales representative, was also deeply involved throughout the project, answering questions, facilitating the installation, and training Taylor’s staff.  Recently, with Taylor’s cooperation, Crider has led personnel from two other Tampa hospitals on tours of Haley’s power system.  One of those hospitals is installing a similar system.  The other is considering such an installation.

Onward and Upward

The fact that the system is designed to allow for modifications as the hospital continues to grow has Taylor thinking.  “With this new power system, we have seen what is possible,” he notes.  “It provides us with the information we need to analyze our power usage and consider new possibilities — opportunities we never would have considered before.”

Putnam Investments

,

INVESTMENT FIRM DEPENDS ON BACKUP POWER SYSTEMS

When you are responsible for superior service for more than 10 million shareholders and 172 institutional clients, you can’t afford to blink.  With more than 3500 employees and six computerized service centers in Massachusetts, London, and Tokyo, Putnam Investments has invested in emergency/backup power systems for all its facilities to assure continuity of service to its customers.

Putnam is one of the largest money-management companies in the world, offering mutual funds retirement plans, college savings plans, insurance products and institutional portfolios.

As the company grew in the late 1980s and early 1990s, Putnam learned about the differences in backup power systems firsthand.  Chronically malfunctioning switchgear installed in 1986 at the company’s first data center led management to reconsider its choice of equipment when planning the emergency/backup system for its headquarters in Boston’s Post Office Square.  Installed in 1990, this new system included a single Caterpillar 800 kW generator and three open-transition automatic transfer switches manufactured by Russelectric® Inc. in nearby Hingham, Massachusetts.

These equipment changes were the result of a scoping process in which Putnam executives and S.B. Sager Associates, the system designer, investigated not only the equipment but also the capabilities, reputation, and performance history of various system suppliers.

“Russelectric® was one of three firms we looked at,” says Barry Mosher, Putnam’s Project Engineering Manager.  “We knew what we wanted the equipment to do, and we compared the failure histories, service records, and so on.  Russelectric® seemed the best choice; there was no question about it.”

Russelectric® designs, builds, commissions, and services switchgear and power control systems for hospitals, data centers, ISPs, airports, and other critical facilities.  Systems can provide sophisticated control functions such as emergency/standby power using either open-transition transfer or live-source, closed-transition transfer; cogeneration; prime power; peak shaving; load curtailment; uninterruptible power; and utility paralleling.

Russelectric® also supports its customers with 7 x 24 field service.  Mosher had heard about this, but in 1991 when one of his transfer switches developed a problem, Russelectric®’s response made him a true believer.

“I had to shut the building down that weekend,” he recalls.  “If I couldn’t fix the switch, we’d be out of business.  I called the [Russelectric®] toll-free field service number and was told the engineer in charge would be paged.  He called back a few minutes later from his daughter’s wedding!  He understood the jam I was in and said he would be there in about half an hour.  He was still in his tuxedo when he showed up.  He quickly fixed the switch and checked the other switches.  I was so impressed!  And I never even got a bill.  That day I learned firsthand that if there is ever a problem, Russelectric® will fix it and fix it right.”

With the growth of the financial industry in the 1990s came the realization that a power outage could badly hurt business.  Putnam’s concerns included more than inconvenienced customers and reduced employee productivity.  The company was concerned about the outright loss of electronic data as well as its ability to conduct routine daily tasks.  Large numbers of checks and statements have to be processed on time.  Other documents and publications have to be printed and mailed on schedule.  Putnam sells all its retail funds through financial advisors, so there are large numbers of inbound calls and e-mail messages from shareholders, financial advisors, and banks in addition to outbound communications from Putnam’s marketing and support staff.

To keep up with its rapid growth, Putnam built new facilities in three Boston suburbs, including Franklin and Andover, between 1994 and 2000.  Designed for each building and installed during construction, a 3000 kW backup power system includes three Caterpillar generators and Russelectric® closed-transition paralleling switchgear.  The backup power system at Putnam’s headquarters was upgraded to 1500 kW and supplemented with a web-based monitoring system that captures data (even from the London and Tokyo facilities) for analysis later.

The Russelectric® power control systems in all four Putnam facilities have redundant programmable logic controllers (PLCs), which coordinate the systems and can switch a facility off the grid to generator power whenever there is a problem.  The controls constantly monitor the utility feed.

“Before we renovated each new building, we conducted a fresh scoping process,” Mosher explains.  “We weeded out the average vendors; we wanted the highest quality we could get.  We looked at competitors’ services, equipment, capabilities, and failure rates, and every time we went through this evaluation process, Russelectric® emerged as the leader — the best value for the dollar.”

In the event of an unforeseen power loss at any of the three suburban facilities, Russelectric® closed-transition switchgear will automatically start the generators, parallel their outputs, and pick up loads in order of priority.  While this entire process takes only about 20 seconds, that is still long enough for computers to “crash.”  With so much at stake, Putnam also invested in uninterruptible power supply (UPS) systems to prevent even the slightest power blink.

Because data centers need absolutely pure power, Putnam is taking no chances.  The suburban power lines that feed these centers are strung between poles and are subject to damage from storms and motor vehicle accidents.  To smooth out any irregularities or anomalies in the power coming into its three suburban facilities, Putnam runs the utility feeds through its UPS systems.  This conditions the utility power and eliminates the damaging effects of harmonic distortion and brownouts.

As with the company’s disciplined scoping process, Putnam’s care is evident in its precautionary pre-storm transfer protocols.  Although the reliability of the utility feed to Putnam’s Franklin facility has since improved, from 1994 to 1999 it failed an average of 14 times per year, with outages averaging 2-3 hours each.  So today, whenever a thunderstorm, blizzard, or ice storm is predicted for the suburbs (4-5 times a year), maintenance personnel use the Russelectric® equipment to parallel the utility feed and the emergency generators and to transfer to emergency power before the storm hits.  Each system has enough fuel to run for 10-12 days if necessary.  In Boston, however, most power lines are underground, utility power is more reliable, and outages are rare, so such precautions are unnecessary.

Because the closed-transition system design transfers each facility’s loads seamlessly from utility feed to backup generators, Putnam can test the systems on a regular basis without the slightest impact on operations.  In addition to the pre-storm transfers, Putnam exercises each of its suburban systems twice a month, during a workday, for four hours.  Every quarter they test them for eight hours.  Neither customers nor employees ever notice these tests.

Under contract, Russelectric® takes care of routine maintenance on the Putnam facilities three times a year and trains Putnam employees in the use of the equipment.

“Russelectric®’s training is conducted by seasoned professionals,” says Mosher.  “But who would expect anything less?  When you tour their plant, you see that every employee takes pride in the Russelectric® name.  The customer is #1, and that comes across in their R&D, their service, and their overall attitude.”
