CT PT Tester

Portable Current Transformer Test Equipment

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.
