Description
VPIS for M.V. cubicles (switchgear)
DXN series of voltage presence indicating system (VPIS) indicates the voltage presence on M.V. cubicles by being installed on the capacitive dividers.
The live voltage indicator (POTENTIAL INDICATOR) can also output interlocking signal to the electromagnetic lock to automatically lock up the switch handle for preventing mis-operation or locking out people from entering into the charged areas.
