Note,between the current 0.2In~Imax,taking the average δe between the maximum and minimum phase error.

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

Half-sinusoid Test

          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
