Control and Relay Panel Testing

At GK Expertise, we deliver complete Control and Relay Panel Testing Services to ensure your protection and control systems operate safely, accurately, and as designed. Our qualified engineers support projects across Oman and Gulf countries with professional testing, verification, and commissioning of control panels and relay panels for substations, switchgear, and industrial power systems. We support new installations, upgrades, shutdowns, and maintenance projects with detailed testing procedures, certified test reports, and on-site technical expertise.

Our Scope of Control & Relay Panel Testing Services
control and relay panel testing

We provide end-to-end testing and commissioning solutions, including:

  • Control and relay panel testing
  • Panel wiring inspection and continuity testing
  • Point-to-point wiring verification
  • Scheme check as per approved drawings
  • Secondary Injection Testing of protection relays
  • Primary Injection Testing of current and protection circuits
  • Functional testing of control, alarm, and trip circuits
  • Interlock and logic verification
  • Pre-commissioning and final commissioning
  • Testing and commissioning (T&C) for substations and switchgear
  • Our systematic approach helps detect wiring errors, logic mismatches, configuration issues, and protection malfunctions before energization.

    Panel Wiring & Continuity Testing

    We verify that every wire is connected correctly according to the approved drawings. This ensures there are no open circuits, wrong terminations, or loose connections that could cause failures during operation.

    Scheme Check

    Scheme check confirms that the control and protection logic matches the design intent. Our engineers review drawings, terminal connections, relay logic, and interlocks to ensure the system will operate correctly under normal and fault conditions.

    Secondary Injection Test

    In secondary injection testing, test signals are injected directly into the protection relays to verify settings, logic, timing, and tripping functions. This confirms that the relay responds correctly to simulated fault conditions.

    Primary Injection Test

    Primary injection testing applies current to the primary circuit to validate the complete protection path, including CTs, wiring, relays, and trip circuits. This test confirms the real-world performance of the protection system.

    Functional Testing

    Functional testing verifies the complete operation of control circuits, alarms, indications, interlocks, tripping, and communication signals. This ensures all equipment works together as intended before energization.

    Commissioning

    Commissioning confirms that all tested systems are ready for safe energization and operation. We support pre-commissioning checks, final commissioning, and handover documentation.
