Ground setter ZON 110M-II-UHL1
Ground setter ZON 110M-II-MCC1 is intended for grounding the neutralization of the power transformer having in neutralization a current transformer for protection against closures to the ground
CONSTRUCTION AND OPERATING PRINCIPLE:
The ground setter of ZON 110M-II-UHL1 is installed in fixed transformer substations in AC networks at a rated voltage of 110 kV.
The ground setter ZON 110M-II-UHL1 together with the drives MD-01-2MCC1 or GDP-00-2UHL1 ensures manual switching on and off under the conditions normalized GOST 15543-70 and GOST 15150-69 for category 2 performances UHL1.
