The Substation Management system will monitor the voltages, currents information of the feeders and the Roster schedules loaded into the memory. It will store the duration of three-phase and single-phase supply timings in a day. During single-phase hour, if the three-phase supply is present, the system will automatically trips the circuit breaker and the event will be recorded in the memory.
The duration of three -phase power supply and single-phase power supply, date, time and schedules status will be displayed continuously in scroll mode. Facility is given to modify the schedule from the system keypad or using the Hand Held Terminal with a password. The daily data like the duration of three-phase supply, single-phase supply and total power-on time will be stored in the memory up to 40 days. This data can be retrieved using the Hand Held Terminals or through PSTN modem at remote management cell.
