11kv Outdoor Oil Type Combined CT PT Metering Unit
1. JLS Type 11kv Outdoor Oil type Combined CT PT Metering Unit
JLS-6,10 three-phase outdoor dry high-voltage power metering box (combined transformer) is made up of two or three single-phase voltage transformers and current transformer. PT and CT are both electromagnetic type.
This type of transformer is application to 50 HZ (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 in high-voltage circuits.
