Cheap circuit breaker in substation Factory

The preferred option for this business case is Option 2 – Risk Based Replacement. Under this option, substation circuit breakers and reclosers are considered for replacement once the benefits that result from their replacement outweigh the costs of doing so (assessed via a quantitative risk assessment process). 4.2 Scope of preferred option

Substation circuit breakers and reclosers are considered critical assets, given their important role in network protection. They are used in the network to open and close (i.e. switch) an electrical circuit under normal and fault conditions, providing safe operational control.

The purpose of circuit breakers is to provide a fast, selective and reliable fault clearing protection system. The substation consists of a main protection system and a back-up protection system if the main protection system fails.

Under this option, substation circuit breaker condition is to be monitored on an individual asset basis. Replacement is driven by a quantified risk assessment for each asset, which compares the cost of replacing the asset with the benefits realised by replacing the asset in terms of risk reduction.

The electronic transformer is also a switching power supply. It is actually an inverter. First, the AC power is converted into DC power, and then the electronic components are used to form an oscillator. What are the troubleshooting methods for transformer faults?
