JLSZW 6KV 10KV Combined Transformer Current Transformer&Voltage Transformer
JLSZW□ -6、 10 three-phase outdoor dry high-voltage electric metering unit (combined transformer) is made up of two or three single-phase voltage transformers (PT) and current transformers (CT). PT and CT are both electromagnetic type. This type of transformer is applicable to 50Hz (rated frequency), three-phase AC, 6kV, 10kV (rated voltage) electric net for power measuring. It is fixed on the high-voltage side of power supply transformer. There is one three-phase active watt-hour meter and one reactive watt-hour meter installed inside measuring box, which are used to directly measure active and reactive appliance in high-voltage circuits.
