On-Site Current Transformer Testing
Current Transformers (CT’s) are used for both Measuring and Protection purposes connecting high power switchgear to the secondary device.
We have now invested in a state of the art CT Analyser which can be used both in the factory for CT tests at the manufacturing stage or on site to provide tests to confirm the specification of the installed CT – either measuring or protection CTs. The CT Analyser (manufactured by Omicron) automatically determines all the relevant CT values and can compare the results with the selected standard.
The following values can be tested using the CT Analyser
- CT Ratio
- CT Phase Angle
- CT Excitation & Saturation
- Burden Impedance
- Winding Impedance
- Saturated Inductance
- CT Polarity
Instrument Transformers Limited can provide these tests using this CT Analyser typically throughout the UK with their experienced test engineers. Whether it is an industrial or commercial installation – we provide the customer with a test report to support the specification of the installed CT, in addition a full test report showing CT characteristics – checked against the standards. We recommend periodic retesting to maintain the validity of the CTs operation.
