Description
JLSZW□-6、10 three-phase outdoor dry high-voltage power metering box (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 electric appliance in high-voltage circuits.
