The reason that the phase current meter of the three-phase asynchronous motor is too low and the other two phases is normal is that it is too normal
If a new motor appears, one phase current is low, and the other two phases are normal. It is possible that the current is low, the phase voltage is high, or the current meter and the transformer have problems
It can also be used to measure the faults at the far end or the proximal end of each phase. If the current balance of each phase is unbalanced, the problem of eliminating the current transformer is the problem of the motor
If it is a new repair motor, and the three-phase voltage balance is the current is too low, there is a problem with the phase turns and wire diameter, two is the current meter and transformer problems.
