11kv potential transformer transformer

JDZ10 type indoor middle voltage is a range single phase, casting resin insulated and full enclosed products. They are used for metering electric energy, voltage control and relay protection in the electric non-useful-ground neutral system up to rated frequency 50Hz or 60Hz rated voltage 11kV grid system. The iron core and winding are casting together, The secondary outlet line is wrapped by outlet box. Primary winding Terminal A is fully insulated, terminal N is for ground. Use for neutral non-effectively earthed system. The voltage transformer is small size and light weight, small space for installation.

General:

This type of voltage transformer is a whole sealing puring insulation pillar type product used for measurement and relay protection in the indoor AC 50Hz or 60Hz/10-12kV power system.
