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 Burden
The burden of a CT is measured as complex impedance.
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 Ratio V
Determining CT ratio by the ratio of two voltages.
CT Rogowski Coil Ratio and Polarity
Measuring unconventional current transformers, such as Rogowski coils.
Voltage Withstand Test
A voltage withstand test of up to 2000 Volts.
VT Ratio and Polarity
Obtain ratio error in percent and an assessment of the polarity of a VT.
VT Burden
Display burden as apparent power in VA with the power factor cosine phi.
Polarity Check
Correct polarity of CTs and VTs with respect to their secondary wiring.
Electronic VT
Precisely measure electronic VTs with small output voltages.
Power Transformer Winding Resistance Continuity of Tap Changer
Measure impedance of power transformer windings and diagnose the tap changer.
Power Transformer Ratio per Tap
Measure the ratio of power transformers of any vector group.
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 CT Ratio Measurement
Measure a CT with a ratio of 400/5 Amps.
Quick CB Contact Resistance Measurement
Measure the contact resistance of a circuit breaker.
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.
Reporting
An interface to an external PC allows uploading of saved test results.
