Liquid Cooled Chokes

  • •By use of liquid cooling, the temperatures in the components can be reduced greatly-ie less stress for the insulation materials and longer life.
  • •Reduced increase of the coolant temperature and lower required flow rates
  • •water cooled reactor for wind frequency converter
  • •three phase line choke is used for converter in wind application.  On the one hand the choke has to smooth the current and on the other hand the choke is part of the line side filter to meet the power quality.

  • Measurement of voltage ratio and check of phase displacement
  • Measurement of short-circuit impedance and load loss
  • Measurement of no-load loss and current
  • Separate-source AC withstand voltage test
  • Induced AC withstand voltage test
  • Partial discharge measurement

Type test

  • Lightning impulse test
  • Temperature-rise test

Special test

  • Partial discharge measurement
  • Measurement of sound level
