PJSW-12 dry-type outdoor AC high voltage power meter box is a modular apparatus consist of dry type high-precision potential transformer, current transformer and electric meter. It is a new product developed by Xingbang with air-insulated box and functions of no-oil filled, small volume, light weight and simple structure. It adapt to meter the outdoor power energy in three-phase A.C. 50 Hz distribution system under 10kV. The voltage transformer and current transformer both can reach 0.2 degree of magnitude accuracy. Due to fully-airtight structure, secondary metering circuit is safe and reliable. This product is an ideal HV power metering equipment for power supply departments to stop power evasion.
