Current meter SCH41160 short circuit (SHCH 41160, SHCH-41160)
Measurement of single-phase fault current zero-phase circuit in AC 380/220V, single phase current measurement range short-circuit 10-1000A
Meters short circuit current SCH41160 digital (hereinafter - the gauges) are used for measuring the current-phase short-circuit phase-zero in AC 380/220V, 50 Hz frequency with the neutral point earthed power supply transformer and the phase shift angle of 30 ° ± 25 °.
Codes NES meters are given in Table.A.
Limit of acceptable relative basic error SCH41160 given by:
δ = ± (10 1 [Jk / J - 1])
where δ - limits of acceptable relative basic error,%;
Jk - the final value of the specified range of measurement, A;
J - the measured value of the short circuit current, A.
