ekor
.sas
- acoustic grounding prevention alarm unit
The
ekor
.sas grounding prevention alarm is an acoustic
indicator which works in association with the grounding
shaft handle and the
ekor
.vpis voltage presence indicator.
Both operate within the same range. The alarm is activated
when there is voltage in the cubicle’s medium voltage
feeder and the lever is inserted in the grounding switch
shaft. A sound then warns the operator that if he performs
the operation, a short-circuit in the network might occur.
This unit is standard on
cgm
.3 system feeder functional
units and supplied to order in the rest of the functional
units.
