Testing of Relays, CRP Panels and Retrofit Solution Service

We specialize in the testing of Numerical Main Protection relays , Auxiliary relays and Control & Relay Panels (CRP) to ensure seamless functionality and integration within electrical systems. The process begins with functional testing of relays, verifying their response under various fault conditions.

This is followed by functional and scheme verification of panels, ensuring all components are properly integrated. We also carry out pre-commissioning and commissioning of panels to validate system readiness.

i)Retrofit & Revamping Solutions

We offer specialized retrofit solutions for substations, focusing on upgrading outdated systems with modern technology.

Replacement of old panels and relays with advanced systems.

Expertise in reverse engineering, enabling the creation of new retrofit schemes even when old conventional systems lack documented schemes.

Implementation of new retrofit schemes based on existing ferrules and connections.

As-built drawing modifications to reflect the updated system.

ii)Testing Activities:

✔ BOM verification and panel scheme checking

✔ Configuration & testing of numerical relays

✔ Functional checks for panel pre-commissioning

✔ Final commissioning of panels

iii)Retrofit Solutions:

Upgrading protection schemes for the proposed device

Dismantling of existing devices/panels and mounting new equipment with required accessories

 Retrofit scheme verification and device configuration
