Russell Electric

Complete systems are custom designed and fully manufactured by Russelectric.All systems are UL listed.Incorporate a variety of sophisticated control functions such as peak shaving and load curtailment.IProgrammable logic controllers (PLCs) are used extensively for system control.Designed for maximum safety and operating simplicitySCADA capable.Touchscreen control available.Alarm and failure system, including annunciation, automatically shuts down an engine generator if required.Redundant PLCs ensure uninterrupted automatic system control even if one fails.System design allows manual start and synchronization of generator sets if automatic controls malfunction.15 LCD HMI touchscreen displays, system one-line, alarms, setpoints, etc.Optional load demand sensing determines the number of engine generators in operation based on the external load.SYSTEM OPERATION Upon receipt of loss of normal power source signal from automatic transfer equipment, system automatically sends command to start engine generator.The first generator set to reach pre-set voltage and frequency is connected to the bus by closing its circuit breaker.System permits first priority loads to transfer to the connected engine generator set, while delaying the transfer of lower priority loads until additional generator capacity has been connected.System manages random paralleling of remaining generator sets to the emergency bus through their individual synchronizers and circuit breakers.System signals lower priority loads to transfer to the emergency power system as generator sets are added to the bus.System manages the shedding of low priority loads if a generator set fails during emergency operation, thereby assuring continuous power to the high priority loads.Upon receipt of signal from transfer equipment that it has retransferred to the normal source, system alerts generator sets to disconnect and shut down.

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.
