We have NABL/ILAC accredited testing facility at our sister company M/s Tesla
Transformers (India) Limited. The approval process for NABL Testing Lab is
currently underway for Tesla Power Equipments & Projects Private Limited.
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 laboratory)
◙ 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 sound 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
