Testing of Capacitor Bank

by

Type Tests on Capacitor Bank

  1. Thermal stability test
  2. Measurement of tanδ at elevated temperature
  3. AC voltage test between terminals and container
  4. Lightning impulse voltage test between terminals and container
  5. Short circuit discharge test
  6. Test of an external fuse in combination with a capacitor
  7. Disconnecting test on internal fuses.

Routine Tests on Capacitor Bank

  1. Capacitance measurement
  2. Measurement of tanδ
  3. Voltage test between terminals
  4. AC voltage test between terminals and container
  5. Test of internal discharge device
  6. Sealing test
  7. Discharge test on internal fuses.

Acceptance Tests on Capacitor Bank

The type tests and routine tests are repeated on samples as factory acceptance tests.
