We have dedicated team of experts for Testing & Commissioning services of all types of Protection Relays, Control & Relay Panels, Switchgear Panels, Transformers, Motors and Sub-stations up to 220KV.

The testing of protection equipment may be divided into four stages :

- Type tests

- Routine factory production tests

- Commissioning tests

- Periodic maintenance tests
