High Voltage Presence Detection Device

Red Lights indicate the presence of High Voltage on the Out/In-coming line. Green Lights indicate the absence of High Voltage on the Out/In-coming line.

Red light on one phase indicates the presence of High Voltage on the one phase of the Tx line due to induction. Induction on one phase is indicated by an alarm signalBAY ALARMSOR2.CHECK CABINET 1- LP LOCKOUT ALARM3.CHECK OIL PRESSURE LOW LOCKOUT ALARM4.CHECK CIRCUIT NO POWER - ALARM5.CHECK VD FAULT SIGNAL ALARM6.CHECK INDICATING & SIGN ALARM1.PHASE DEVIATION ALARMBAY ALARMS
