Integrated Substation Condition Monitoring (NIA_NPG_002)
The reliable operation of circuit breakers is crucial to the dependability and safety of the distribution network: in the event of a circuit breaker failing to trip and interrupt fault current, the next zone of protection is called upon to operate, resulting in a greater number of customers falling off supply and a greater financial impact on the business. Northern Powergrid is committed to making greater use of asset condition and performance data to inform asset management decisions. To facilitate more accurate intervention strategies and better supported investment decisions, greater and wider use of real time monitoring and diagnostics on the distribution system is needed.
This project aims to gather circuit breaker performance and operating environment data through the use of a real time monitoring system applied to 100 circuit breakers in seven primary substations
