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

Energy metering error is less than 3 percent

Working Atmosphere

Limiting ambient temperature-40°C~+70°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
