5. Current check
If the over current protection relay still releases, even if the volt-
age is correct, measure the current in all phases.
Example 1
The current is not same in all phases: Fault in the motor wind-
ings. The motor should be isolation measured by a competent
person or exchanged.
Example 2
The current is to high in all phases. The most probable reason
is that the motor load is higher than calculated either because
it has been wrongly calculated from the start or because some-
thing is obstructing the motor. You may also have a fault in the
motor and then it should be isolation measured by a competent
person or exchanged.
