Various diagnostic techniques are used by utilities to carryout circuit Breaker diagnostic with a view to determine earlier failure probability. The present paper describes the result of on-sight measurement of various parameters for breakers from 11 kV to 800 kV. The measurement includes several tests like timings, coil currents, contact resistance, velocity & dynamic contact resistance. Significance of the tests in light with the experimental results have been discussed in the paper. © 2015, Central Board of Irrigation and Power. All rights reserved.
