2. Electronic Transformer Test Function

Introductions

Electronic transformer calibrator is mainly used to calibrate the electronic transformer that complies with IEC 61850-9-1, IEC 61850-9-2, IEC 61850-9-2LE standards. Calibration includes: ratio error, phase displacement, delay, polarity, etc. Equipped with small-signal input terminal, it can calibrate the small-signal output of the electronic transformer as well as the small-signal input merged unit, etc.

Display: TFT LCD touch screen with resolution 800x600 pixels.

Main features:
It can test for electronic voltage transformers (having an analogue output or a digital output): test according to IEC 61850-9-1, IEC 61850-9-2, IEC 61850-9-2LE standards.
