Testing and commissioning of substation equipment

We have dedicated team of experts for Testing Commissioning services of all types of Protection System, Control & Relay Panels, Switchgear Panels, Transformers, Motors and Sub-stations up to 400KV.

  • Testing and Commissioning of Protection Systems of all types of Relays including Electromechanical to Numerical Relays of all Manufacturers
  • Third Party Inspection Services for Pre-commissioning activities.
  • Sophisticated Testing Instruments for Testing of Power System Equipments and Numerical Testing Kit for Testing of Protection Relays.

Services offered for Testing and commissioning of substation equipment (testing CIRCUIT BREAKER)

1. Test the HV/EHV class Circuit Breakers of various makes like ABB, BHEL, CGL, ALSTOM, SIEMENS, NGEF Etc. for following tests:

  • Circuit Breaker Operation times, like C, O, C-O, O-C-O…
  • Travel Characteristics of breaker contact / mechanism
  • Trip & Close Coil Current characteristics
  • Static Contact Resistance
  • Dynamic Contact Resistance (DCRM)
  • Tan Delta of Grading Capacitors and Dew Point Measurement of SF6

2. Testing a particular breaker at any location using our equipment for above parameters.

3. Testing a group of circuit breakers in a substation using the customer’s equipment.

4. Test data is handed over to the customer in the form of a hard copy – wherever the customer has access to a computer, we provide help to record the data in its soft format through SCOPE’s “CPLOT” software.
