Russell Electric

Russelectric® custom designs and builds low- and medium-voltage power control systems to meet the stringent performance and reliability requirements of data centers, airports, hospitals, communications, energy, defense, and other mission critical facilities. Russelectric systems can control on-site emergency generator operation, synchronizing, and distribution. Switchgear can provide open-transition transfer or utilitygenerator paralleling for closed-transition transfer. Systems can be designed to manage sophisticated control schemes such as: Every Russelectric power control system is custom-designed and manufactured to specific customer requirements and stringent performance, safety, and quality standards. All components are of the absolute highest quality. Redundant industrial-quality PLC controls ensure flawless system operation — even in the event of a control failure. Controls are designed to allow fast, easy upgrades such as the addition of accessories or advanced monitoring and control capabilities.

All systems are UL listed Selector switches for openclosed transition, automaticmanual paralleling of generator or utility sources, and automaticmanual retransfer to normal source provided Active synchronization Redundant PLC controls SYSTEM OPERATION Soft loading systems are utility paralleling systems capable of sustained paralleling. Whereas many load curtailment systems transfer loads from the utility power source to the generator all at once (in 100 milliseconds or less), soft loading systems parallel the two live power sources, allowing a more gradual transfer of loads (up to 20 seconds or longer). This eliminates any momentary dip in voltage and the disruptive effects of block loading. Conversely, retransfer from the generator source to the utility source is accomplished through soft loading. System specifiers should be aware that soft loading systems usually require utility-approved protective relaying and control measures.

REMOTE MONITORING OF ALL POWER SYSTEM FUNCTIONS A Russelectric® SCADA system allows the user to monitor system operation, acknowledge alarms, and review PLC setpoints and alarm history. All screens are custom designed for each power control system, providing the most realistic, accurate display possible. BASIC SCADA The basic SCADA system includes a dynamic one-line display with changing color codes to indicate real-time power switching device status and power source connection to the loads. Event logging, alarm logging, and help screens are also included. OPTIONAL ENHANCEMENTS FOR ADDED FUNCTIONALITY Optional enhancements include highly detailed graphic displays of the physical arrangement of equipment, control panel close-ups, instrument displays indicating actual values, and the ability to initiate control functions. An optional simulation system, based on SCADA system graphics, allows operator training off-line without affecting any operating system parameters.

First medium-voltage automatic transfer switch tested, listed, and labeled by UL for use on emergency systems Available at 5-15kV, 1200-Amp and 2000-Amp continuous current ratings Configurable for open- or closed-transition transfer Adjustable Center-Off Time Delay Russelectric® RPTCS programmable microprocessor-based control system Adjustable center-off time delay UL TESTED, LISTED, AND LABELED Russelectric was the industry leader in obtaining UL listing for its medium-voltage transfer switchgear. All Russelectric RTS Series circuit breaker automatic transfer switches have been fully UL tested, listed, and labeled under UL 1008A. In addition, all Russelectric medium-voltage transfer switchgear (operating above 600 volts and below 15 kV) is listed per UL category “Circuit Breakers and Metal-Clad Switchgear – Over 600 Volts (DLAH)”. It is also designed, manufactured, and tested to meet or exceed stringent IEEE, NEMA, and ANSI standards. RUGGED HIGH SPEED SWITCHING DEVICES Russelectric RTS Series Russelectric Medium-Voltage Circuit Breaker type Automatic Transfer Switches are designed to transfer electrical loads from a normal power source to an emergency power source upon reduction or loss of voltage and to retransfer loads when normal power is restored. Supervised by the advanced RPTCS microprocessor control, Russelectric Medium-Voltage Circuit Breaker Automatic Transfer Switches direct the flow of electric power through the carefully timed openingclosing of circuit breakers.

Drawout modules, metal-clad construction, segregation of controls from power elements, and separately accessible grounded compartments are all part of Russelectric’s design safety philosophy. All switches are designed for unattended automatic operation, but include controls for manual operation. Designs provide accessibility for maintenance, trouble-shooting, and component replacement. All switches are factory tested for functionality prior to shipment. Interconnect wiring diagrams enable proper interfacing of switches. DESIGN, MANUFACTURE, AND TESTING All bus is formed, cut, and punched before being insulated with high-dielectric epoxy coating to guarantee the integrity of the insulation and ensure maximum performance. Busbars pass through track-resistant, polyester glass barriers between cubicles. Main bus joints have silver-plated connections and are insulated with preformed boots. All transfer switches are thoroughly inspected and tested both mechanically and electrically under simulated operating conditions before shipment.

All systems are UL listed Selector switches for openclosed transition, automaticmanual paralleling of generator or utility sources, and automaticmanual retransfer to normal source provided Active synchronization Redundant PLC controls Soft loading power transfer available SYSTEM OPERATION Choice of either momentary (100 milliseconds or less) paralleling with the utility or sustained paralleling for soft loading. Paralleling of generator sets with the utility (upon return of the utility source after power interruption). System testing in closed-transition mode with no interruption of the load. Generators are paralleled with the utility and the load is transferred to them. Upon completion of testing, the load is retransferred through closed-transition to the utility source without disturbance. Configurable for peak shaving or utility-sponsored load curtailment programs.

SYSTEM FEATURES All systems are UL listed Selector switches for openclosed transition, automaticmanual paralleling of generator or utility sources, and automaticmanual retransfer to normal source provided Active synchronization Redundant PLC controls SYSTEM OPERATION Load curtailment programs involve an agreement between an electric power customer and a utility or power provider, whereby the customer agrees to meet a portion (or all) of its power needs on its own during periods of high utility demand in return for special rates, discounts, or other concessions from the utility. Under such programs, the power customer typically agrees to drop portions of their load off the grid — at the utility’s request and with advance notice — leaving them to meet their own power needs. In response to a notice from the utility, the customer powers up its own generators, and transfers all loads (either all at once or gradually through paralleling with the utility) to the generators. This reduces the total power demand on the utility, allowing it to better meet unusually high demand while avoiding potential brownouts or blackouts. Once the period of high power demand, or the time period agreed upon between the customer and utility has passed, the customer is free to transfer all loads back to the utility. Russelectric® power control systems can be designed to accommodate load curtailment programs using closed-transition transfer, utility paralleling, andor soft loading control schemes.
