1 system: T mark, measured by phase shift method; no T mark is measured by cross-phase method.
2 The output range (pulse number) of reactive energy transmitter is calibrated according to 1kVarh. For reactive energy measurement, when the output is negative, it means that the capacitive impedance of the system is the largest; when the positive value is output, it means that the inductive impedance of the system is the largest.
