Testing and commissioning of substation equipment

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.
