Precision Monitoring for Reliable Protection
Successful power system operation starts with accurate data. Current Transformers are the “eyes” of your protection and metering systems. At GS Green Energy, we provide essential testing and commissioning services that help you meet your operational goals by ensuring that high-line currents are translated into precise measurable values for relays and meters.
Managing CT Health Requires:
- A comprehensive understanding of the transformation ratios under both normal and abnormal operations.
- Knowledge of a wide variety of equipment from different manufacturers.
- The successful application of industry codes and standards to ensure system sensitivity.
Our Specialized CT Analytical Services Include:
- Magnetization (Knee Point) Analysis: We identify the saturation limits of the core to prevent relay maloperation during heavy fault conditions.
- Ratio and Phase Error Verification: Utilizing high-precision injection to ensure transformation accuracy matches your billing and protection requirements.
- Winding Resistance & Polarity: Essential checks to ensure directional sensing for protection relays and to detect internal winding short-circuits.
- Insulation Resistance (IR): Verifying the dielectric strength between primary/secondary windings and the ground to prevent catastrophic failure.
