Product Description
This series of metering boxes are improved on the basis of similar products. They are suitable for electric energy measurement in outdoor AC power systems with rated frequency of 50Hz, rated voltage of 10kV and 6kV. It is an ideal substitute for old-fashioned oil-immersed products. This series of products is composed of two parts: voltage and current combined transformer and measuring instrument box. The transformer is equipped with two independent voltage and current transformers, which are divided into phases A and C. The outer wall of the combined transformer is equipped with power and reactive watt-hour meters, as well as a joint junction box for testing, and the meter box is used during operation. Covered to prevent electricity theft.
Ambient air humidity: cap + 40 ºC, lower limit - 15 ° ºC
Altitude: < 1000 m (if need higher elevation, the rated insulation level increase)
Needs: amplitude, intensity of no more than 8 degrees
Air relative humidity, average no greater than 95%, the monthly average no greater than 90%
No fire and explosion danger, serious pollution, chemical corrosion and the site of violent vibration
