The Revolution in Current Transformers Testing
CT Analyzer - Current Transformer Testing
OMICRON`s CT Analyzer automatically measures all relevant CT parameters and compares the results with the selected standard. Thus the equipment can deliver a complete assessment to the standard within seconds by the push of a button.
The CT Analyzer provides fast and cost-efficient on-site testing and verification of current transformers for protection and metering applications. Supplier of CTs, HV transformers and switchgears also use the CT Analyzer for testing during development and manufacturing.
For automated testing of multi-ratio CTs without re-wiring, the CT SB2 Switch-Box is available for the CT Analyzer.
Features and Benefits
- Highest accuracy: typically 0.02% ratio and 1 min in phase for field verification
- Extremely small and lightweight (< 8kg/17 lb), unmatched portability for on-site testing
- Automated assessment according to defined IEEE or IEC standards
- Reduced commissioning time due to fully automatic testing (test cycle typically < 1 min)
- High level of safety - testing at low voltages (max. 120 VAc)
- Integration of the CT Analyzer into automated test environment possible via remote interface
Applications
A wide range of measurement functionalities can be provided:
- CT ratio and phase-angle accuracy with consideration of nominal and operational burden
- CT polarity
- CT winding resistance
- CT excitation / saturation
- Burden impedance
- Saturated and unsaturated inductance
