Protection Relay Testing Services

Protection Relay Testing Services

At Potential Power Services (PPS), we provide specialised high-voltage protection relay testing services to ensure the reliability, accuracy, and safety of your power systems. Properly tested protection relays are critical for preventing equipment damage, reducing downtime, and maintaining the stability of electrical networks.

Our experienced engineers use advanced testing equipment and industry-standard procedures to verify relay performance, detect malfunctions, and optimise protection settings. This ensures your systems operate safely and reliably under all conditions.

Key HV Protection Relay Testing Services Include:

  • Relay Calibration & Functional Testing – Verifies correct operation and response times.
  • Trip Testing & Simulation – Simulates fault conditions to ensure proper relay activation.
  • Timing & Pick-Up Setting Verification – Confirms relays operate within designed parameters.
  • CT & PT Ratio Verification – Ensures accurate current and voltage inputs to relays.
  • End-to-End System Testing – Checks coordination between relays, breakers, and other protective devices.
  • Digital & Numerical Relay Testing (IEC 61850) – Validates communication and automated protection functions.
  • Fault Analysis & Diagnostics – Identifies mis-operations or potential weaknesses in relay schemes.
