Automatic Class 0.02 China High Quality Current Transformer CT Analyzer

Product Description

GF106 PORTABLE 0.02% high accuracy DC method current transformer testing ct analyzer

GF106 portable CT analyzer is mainly used for field or lab testing, it can finish the measurements (M) and protection (P) class CT, PT and TYP class CT. Adopt 7 inch touch TFT LCD, self-equipped mini type printer supporting field printing; supporting to use USB flash disk to dump data. The CT PT Analyzer is the most complete and easy-to-use testing system for protection and metering CTs according to IEEE and IEC standards.

The CT Analyzer automatically determines all relevant current transformer values and compares the results with the selected standard. The device evaluates the current transformer as per the IEC or IEEE standard within seconds with the push of a button.

It facilitates fast and economical on-site testing and calibration of metering and protection current transformers. Manufacturers of current transformers, high voltage transformers and switchgear also use the CT Analyzer for tests during development and production.

Applications

The following values can be determined using the CT Analyzer:

Accuracy of the ratio and phase angle, taking into consideration the nominal burden and connected burden

CT excitation and saturation

Burden impedance

Winding resistance

Saturated and non-saturated inductance

CT polarity
