Current transformers are used for relaying and metering purposes in electrical power systems. They connect the high power primary side to the protection and metering equipment on the secondary side. Depending on the application they are used for, current transformers are designed differently.
The Omicron CT Analyzer is the most complete testing system for protection and metering CTs according to IEEE and IEC standards.
It allows all types of single and multi-ratio current transformers to be tested on-site in power system grids. Manufacturers of CTs, transformers or GIS use the Omicron CT Analyzer in their production facilities and test / development labs.
The Omicron CT Analyzer offers a wide range of measurements, such as:
- CT-ratio and phase-angle accuracy with consideration of nominal and operational burden for various currents
- CT winding resistance
- CT excitation / saturation (unsaturated and saturated)
- ALF and FS (direct and indirect)
- Burden impedance
- CT residual magnetism
Protec also offers the Omicron CT SB2 for rent, as an accessory to the CT Analyzer.
