Omicron CPC 100
Universal testing device for electrical diagnostics
Electrical tests on transformers, current transformers, voltage transformers, grounding systems, lines and cables, and circuit breakers can be performed with the CPC 100.
The patented test system replaces several individual testing devices and offers new, innovative testing methods.
The CPC 100 is the base for multiple accessories. These facilitate further applications, such as tan delta measurements, as well as line and ground impedance measurements.

Omicron CT Analyzer
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
