Objectives Asset reports shall be produced at periodic intervals, typically each calendar month or other frequency set by the user. The content and format of reports may typically include: Graphical representation of pd activity on each switchboard Trending of pd activity with appropriate alarm thresholds for high rates of change in activity Summary of circuit breakers tripped and plot of dc trip current profile for each event Representation of the cumulative energy (I2t) interrupted by each circuit breaker Graphical representation correlating pd activity and environmental conditions The project success criteria are defined as follows: Successful installation of circuit breaker condition monitoring equipment and partial discharge monitoring equipment at 7 substations with a total of 96 panels Successful collation of data from installed equipment Production of asset performance reports to inform Maintenance Policy and asset replacement/refurbishment decisions Initiation of remedial work or other intervention to improve circuit breaker performance Improvement of circuit breaker performance in relation to Failure on Demand, slow opening, etc. Prevention of an incident relating to circuit breaker failure by triggering intervention Trending of partial discharge for specific circuit breakers and circuit breaker by manufacturer and type Establish appropriate alarm thresholds for each circuit breaker type Demonstrate trends in dc trip coil profile for specific circuit breakers and circuit breaker by manufacturer and type Establish acceptable profile envelope for each circuit breaker type Trigger post fault maintenance by I2t measurements Demonstrate the relationship between environmental operating conditions and the level of partial discharge activity Demonstrate the relationship between environmental operating conditions and dc trip coil profile
Abstract The reliable operation of circuit breakers is crucial to the dependability and safety of the distribution network, where failure of a circuit breaker to function causes the next zone of protection to operate, resulting in a greater number of customers off supply and consequently a greater financial impact on the business through IIS penalties. 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 several common types of switchgear. The method proposed is an Integrated Substation Condition Monitoring system (ISCM) comprising: Monitoring of partial discharge activity DC trip coil profiling including battery voltage monitoring Operating/breaking currents & times (I2t)Operating environment - temperature & humidity The majority of sensors proposed are already used by Northern Powergrid, the key area of development is the integration of all the sensors into one system, allowing the correlation between variables to be explored and trends in circuit breaker performance to be identified.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
