CT (Ratio, Polarity & Knee-Point) Testing
CT (Current Transformer) Testing evaluates critical parameters like ratio accuracy, polarity, and knee-point voltage to ensure precise measurement and protection in electrical systems. This testing guarantees CT reliability for metering and protective relays in substations, industrial plants, and utility networks.
Ratio Accuracy Testing
Verifies the CT’s transformation ratio for accurate current measurement, billing integrity, and relay coordination.
Polarity Verification
Ensures correct phase alignment to avoid malfunctioning relays, misoperation, and measurement errors.
Knee-Point Voltage Testing
Determines the saturation point critical for differential protection, fault isolation, and system reliability.
Compliance and Detailed Reporting
Conducts tests per IEC/IS/IEEE standards with comprehensive reports, trend analysis, and corrective actions.
