Power and Transformer Stations

Operating transformer stations safely

Control voltage

High availability starts with a reliable supply

Control voltage circuits must be monitored for electrical safety; after all, an undetected electrical fault is as significant as unexpected system downtime and also significantly increases the fire risk. At the same time, unplanned service interventions can be expensive and time-consuming. Some transformer station insurers also demand effective condition monitoring systems. The Bender condition monitoring system gives you a clear overview of all the relevant data for your system.

UPS

A safe supply until the generator is running

An uninterruptible power supply (UPS) is used to ensure the supply of critical electrical loads in the event of problems in the power supply. The UPS systems (normally battery or oscillating weight systems) bridge the period until the emergency power systems (generators) are activated or the network is available again. Electrical safety is continuously monitored by Bender products, including offline monitoring.

Voltage monitoring

Monitoring of three-phase AC systems

The VMD258 analog voltage relay monitors three phase AC systems for under and over voltages (window function) It’s internals are based on analog technology and omit the use of a microprocessor, which makes this relay suitable for nuclear and some demanding military applications. The auxiliary voltage supply can be derived from the system to be monitored. Both, system and supply are separated by a dual layer of insulation for additional internal safety and reliability. Special filter chokes dampen potential electronic noise stemming from the monitored power system. The response values for under and overvoltage and also for time response delays can be adjusted to varying levels.
