PITE 9353 Three-phase Kwh Meter Test Equipment

PITE 9353 Three-phase Kwh Meter Test Equipment

Our power meter test equipments have been active players in the market since the year 1975 before PITE acquires Haiyan. With more than 35 years rich experience and expertise in developing and manufacturing power meter calibrating equipments, PITE’s HY series testing systems have been widely applied by metrological institutes, QC department, test laboratories, meter manufacturer and management dep
HY9353 consists of the latest power electronic developments, newest digital measurement engineering and system-control software solutions according to the actual standards. It is specially designed to calibrate all 3 phase electronic and inductive watt-hour meters, 3 phase multi-rate meters and single phase power meters (optional). It covers reactive power meters of different measuring theories including 3 phase 4 wire true reactive meter, 3 phase 3 wire true reactive meter, 3-element 90°artificial reactive meter, 2-element 90°reactive meter and 2-element 60°reactive power meters.
