In-phase : If the phase difference is about 0°~30° or 330°~360°, it is
in-phase polarity.
Out-phase
phase, the phase of the current lead clamped by CT1 and CT2 are not in-
phase.
Er : Failure to identify normally. This may be caused by low current
amplitude, co-frequency signal interference, or others.
