CONDITION ASSESSMENT UTILIZING ANALYTICAL TESTING TECHNIQUES

摘要

Analytical testing of mineral oils used in oil circuit breakers is a cost effective way to identify necessary condition-based maintenance. Failure and forced outages can be minimized by implementing an effective oil circuit breaker maintenance program resulting in significant savings. This paper presented information on the key analytical tests used to identify abnormal conditions within oil circuit breakers and as detailed by the three case studies. Strong correlation exists between analytical testing techniques and findings in the field. By examining analytical test data, effective inspection and maintenance intervals can be established along with resampling frequencies.
