OMICRON Video Series:
Intensive testing of CTs, VTs and power transformers.
CT Ratio Polarity and Burden
Measures ratio error and - for Inom - also the burden. Assesses the polarity of the CT.
CT Current Booster
For applications requiring up to 2000 Amps, the current booster CP CB2 can be used.
CT Winding Resistance
Knowing secondary winding resistance allows determination of accuraccy limit factor and CT time constant.
CT Excitation Curve
The excitation curve is recorded with high accuracy according to ANSI or IEC standards.
CT Rogowski Coil Ratio and Polarity
Measuring unconventional current transformers, such as Rogowski coils.
Power Transformer Winding Resistance Continuity of Tap Changer
Measure impedance of power transformer windings and diagnose the tap changer.
Contact Resistance Measurement
Measure low-ohmic contact resistances, such as switching contacts or clamp connections.
Quick Standard Test Card for multiple applications
Quick mode allows manual controlling of all basic functions of the CPC.
Quick Measuring the Threshold of a Primary Relay
Increase the current until the switch trips and measure the current when the contacts open.
Quick Primary Testing of IDMT Relays without Trip Contact
Determine the current tripping characteristic of a switch.
Quick Power Transformer Short Circuit Impedance Measurement
Measure the short-circuit impedance of a power transformer at different frequencies.
