Tests of Shunt Reactor

As per IS 5553 the tests performed on an EHV or UHV shunt reactor can be categorized in three different groups.

  • Type tests
  • Routine tests
  • Special tests.

Type Tests of Shunt Reactor

The following tests are essentially performed on a shunt reactor as type tests

  1. Measurement of Winding Resistance.
  2. Measurement of Insulation Resistance.
  3. Measurement of Reactance.
  4. Measurement of Losses.
  5. Dielectric Withstand Tests
  6. Temperature Rise Test

Routine Tests of Shunt Reactor

The following tests are essentially performed on a shunt reactor as Routine tests

  1. Measurement of Winding Resistance.
  2. Measurement of Insulation Resistance.
  3. Measurement of Reactance.
  4. Measurement of Losses.
  5. Dielectric Withstand Tests

Special Tests of Shunt Reactor

The following tests are essentially performed on a shunt reactor as special tests

  1. Measurement of Zero Sequence Reactance.
  2. Measurement of Mutual Reactance.
  3. Measurement of Acoustic Sound Level.
  4. Measurement of Vibration and Stress on tank.
  5. Measurement of Magnetizing Characteristics
  6. Measurement of tan delta of winding.
  7. Dissolved Gas Analysis of Insulating Oil.
