δi=δi-δe.(δI: phase error,δI: phase displacement when the working current at i time,δe:average phase displacement)

Half-sinusoid Test

At 42.4A, the energy measurement error is less than 3%.

Working Atmosphere

Limiting ambient temperature -40°C~+70°C,Relative humidity (RH) ≤98(25°C),Altitude ≤3000m

Main Electric performance

The withstand voltage between the primary and secondary windings is no less than 3kV and insulation resistance is no less than 1GΩ
