Abstract :
ABSTRACT In operation electricity energy source in substation, is direct current source. Source energy for control always have reliability and high stability, Because this requiment used as direct current source. System direct current for substation supplied to rectifier and battery was two parallel connector with load in normal system direct current will supplied directly, however interference so battery will work automatic. Supplied load with certain time close. The cause of the occurrence of interference in the MCB lost contact caused by spring / per loose in the MCB so it can not trip, to turn on the alarm light is done addition of the relay to prevent MCB lost contact so with the monitored 110 VDC supply at MCB in cubicles 20 KV DA-4 then There is no more alarms arise because the security is reliable so as to Increase the readiness of work Relai at cubicles 20 KV and increase sensitivity in carrying out substations monitoring. To protect the tool protection relay, PMT motorcycle movers and PMS and tool communication still fuction, so battery must able for supplied power tools even in condtion without changer as well in condition blackout. So battery have role very important in system electricity energy.
