FRTU
Feeder Remote Terminal Unit
The Feeder Remote Terminal Unit (FRTU) monitors all sub-station equipment and acquires data from all incoming and outgoing feeders on a real-time basis. It captures status signals of devices and conducts automatic data logging to provide substation level control. In addition, it monitors entire substation equipment, viz., breakers, transformers, feeders, batteries, transducers, energy meters, etc., thus facilitating energy management, load forecasting and scheduling, and eventually leading to substation automation.
FRTU is equipped with appropriate acquisition and data management software and interfaces like LAN and/or GPRS/4G to work as a full-fledged SCADA system.
