TME High Power Lab

Thai Maxwell Electric's High Power Laboratory

Thai Maxwell Electric's High Power Laboratory (HPL), in collaboration with the Electricity Generating Authority of Thailand (EGAT), is a TIS 17025-2548 (ISO/IEC 17025 : 2005) accredited laboratory (issued by the Thai Industrial Standards Institute (TISI), Ministry of Industry, Kingdom of Thailand) capable of conducting the following type and routine tests according to IEC or IEEE standards:

Distribution transformers (up to 36kV)

Type tests

  • Short-circuit withstand test (up to 500kVA)
  • Impulse withstand test
  • Temperature rise test
  • Partial discharge test

Routine tests

  • Measurement of voltage ratio and check of phase displacement
  • Measurement of winding resistance
  • Insulation resistance test
  • Measurement of no-load loss and current
  • Measurement of short-circuit impedance and load loss
  • Measurement of reactance
  • Separate source AC withstand voltage test (applied potential test)
  • Short-duration induced AC withstand voltage test (ACSD)
  • Oil dielectric strength test

Instrument transformers (up to 36kV)

Type test

  • Short-time current test (for current transformer)
  • Short-circuit withstand capability test (for voltage transformer)
  • Temperature rise test
  • Lightning impulse test
  • Determination of errors

Routine test

  • Power frequency withstand test
  • Partial discharge measurement
  • Inter-turn overvoltage test
  • Determination of errors

TME's High Power Lab is the only such facility available in Thailand and offers its testing services to transformer manufacturers. Please contact us for more details.
