Testing facilities available as per IEC:60076 / IS:2026 Standards
ROUTINE TESTS
- Measurement of voltage ratio and check
of phase displacement - Separate – source AC withstand voltage
test (applied voltage) - Induced AC over voltage withstand test
- Measurement of no load loss and current
- Measurement of winding resistance
- Measurement of impedance voltage, short-circuit impedance and load loss
- Partial discharge measurement (At third party labotary)
- Function- and insulation test of control wiring, auxiliary operation, tests on on-load tap changers, where appropriate
TYPE TESTS
- Lightning impulse (LI) test
- Temperature-rise test
SPECIAL TESTS
- Determination of sounds levels
- Measurement of zero-sequence impedance(s) on three-phase transformers
- Measurement of the harmonics of the no load current
- Measurement of insulation resistance to earth of the windings, and between the
windings
