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.

 

The CT SB2 switch box is available as an accessory to the CT Analyzer for automated testing of current transformers with multiple taps, without the need for complex and time-consuming rewiring.

 

Key features

 

Highest measurement accuracy: 0.02 % / 1 min when calibrating on site

Very small and lightweight (< 8 kg / 17.4 lbs), easy to transport for on-site testing

Automatic evaluation according to IEC and IEEE standards

Short commissioning times (duration of the automatic test < 1min)

Excellent workplace safety - Tests run at max. 120 V

Integration into testing routines using Remote Interface Control

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
