The standalone version of ETOS® lets you evaluate and record all relevant operating data of your power transformer, such as monitoring the tap-changer or evaluating transformer utilization. ETOS® helps with focused planning of operation and maintenance. Our open ETOS® system can connect sensors from other manufacturers and combine all of the signals in a cabinet. ETOS® complements existing secondary control cabinets and tap-changer drives. Customized upgrades ensure you always have the best configuration for future tasks.
