PW-VP50 CT Polarity Checker
pv
PW-VP50 CT Polarity checker is the favorable meter which can be used for field CT and transformer polarity test in power plants, substations and any other application which may need to check the polarity.
Features

 

  • The master machine supports both single pulse trigger mode and cyclic pulse trigger mode. The sending period and current amplitude of pulse can be set freely, and three-phase output or single-phase output mode can be also selected.
  • The slave machine is connected to each secondary terminal of CT one by one, and the slave machine will automatically collect the waveform of induced pulse current for auto-judgment.
  • The test result, CT polarity, will be indicated through the indicator light and buzzer.
  • PW-VP50 adopts special design of constant current output mode so that it is with high load capacity.
  • Within built-in Li-Battery, The kits can work continuously for 8 hours with one full charging.
  • The test result of PW-VP50 will not be affected by the length of wiring, to ensure the stability and reliability of polarity test process.
  • The PW-VP50 adopts the hand-held structure design, small size, light weight,only 0.25 to0.5kg each unit.
