Induced Over- Voltage Withstand Test (DVDF Test):-

This test checks the inter term insulation.  For a 11 KV/433 V transformer, 866 volts are applied at the 433 V winding with the help of a generator for 1 minute. This induces 22 KV on 11 KV side. The frequency of the 866 V supply is also increased to 100 Hz.

transformer testing Purpose of Induced over voltage test of transformer:

  • To secure that the insulation between the phase windings, turns, coils, tapping leads and terminals.
  • For non-uniformity insulated windings the insulation between these parts and earth.
  • Withstand the temporary over voltages and switching over voltages to which over voltages and switching over voltages subject to the transformer during its lifetime.

  • Ensure that the transformer is not cut into one of the electrical supply lines.
  • This causes the resonant effect to occur, causing high vibration voltage waves that may damage the transformer if there is a weak isolation.

  • Discovering the air gaps between the layers of the windings to find out the efficiency of insulation between these layers and other layers and high voltage high-frequency we use will detect these air gaps.
