Analysis of Disconnection Circuit Breaker Reliability

For the modern human, electricity has become anessential part of life. It is first when the power goes out that societystops and the need of electricity becomes obvious. The largestpower failures have been caused by broken devices in power grids.This project examined different ways to analyze the reliability, lifespan and number of failures over time for the device disconnectingcircuit breaker in power grids.Given data for the circuit breakers has been sorted intodifferent files and the main method used, was linear regression,which were applied on the sorted data. The result showed that thevalues of the circuit breakers deteriorated over time, and this willbe presented in more detail in this report. It can be concluded thatthe disconnecting circuit breakers ages like expected, except forone parameter that gave unexpected result
