In a world where cost control is gaining importance, this CT tester not only lowers testing costs by being simple, fool-proof and fast. It also allows utilities to pursue the very important (yet at many times forgotten) task of testing installed CTs for detecting tampering, and minimizing losses due to faulty CTs.
It features the following offline test capabilities:
– Burden based CT ratio and phase error measurements
to an accuracy of 0.02%
– Excitation measurements for most metering Class CTs
– CT secondary winding resistance
– CT 1.6 kHz Admittance test
– CT and PT Burden test
– CT and PT polarity check
– Batch testing of metering CTs
– No name plate CT Class Estimation
– Record download to USB Flash or optionally via Bluetooth to an
Android tablet or phone.
– Remote control via Bluetooth
– Multitap, option for a 5 ratio metering CT
