Study of electric discharges activity in induction motors with an operating voltage of 380 V

The work aimed at studying into applicability of control methods for partial discharges parameters for induction motors with an operating voltage of 380 V.

The study identified the theoretical background of possibility for the partial discharges inception at low supply voltage. Using existing methods of the partial discharges parameters recording, the measurements were carried out on a large number of low voltage electric motors.

The obtained results confirm the partial discharges presence in the low voltage motors and point to the feasibility of the partial discharges monitoring methods application in insulation of the critical low-voltage motors.
