CT PT Tester

Portable Current Transformer Test Equipment

 FB IMG 1672939596101
  • Test various CTs (including TP class) : excitation characteristics (volt-amps),  ratio, polarity, secondary winding resistance, secondary burden, ratio error and phase displacement.
  • Automatically measures CT, VT parameters, including knee point voltage / current, 10% error curve, the accuracy limit factor (ALF), instrument security factor (FS), the second time constant (Ts), remanence coefficient (Kr), saturated and  unsaturated inductance.
  • Tests meet IEC60044 GB1208 (-1)  GB16847 (IEC60044-6)
  • Based on the advanced principle of low-frequency testing methods that meet the CT test on knee voltages up to 30KV.
  • Store 2000 groups of test data that isn't lost when the power is turned off.
  • On completion of testing the data can be copied to a PC by USB disk for analysis and Word  reporting.
  • Tests are simple and convenient, one-click  completes testing of CT secondary resistance, excitation, ratio and polarity.
