What are high voltage circuit breakers and types? We all know that electrical transmission networks are now protected and controlled by high voltage which varies but the transmission of power work is usually taught to be 72.5KV or higher.  High voltage circuit breakers are nearly always solenoid-operated with current sensing protective relays operated through a current transformer.  In substations, the protective relays scheme can be the complete protection equipment and buses from various types or categories of overload or ground or an earth fault. High voltage circuit breakers are broadly classified by the medium used to extinguish the arc. There are mainly four (4) categories or types of high voltage circuit breakers and these types or categories are namely; Air Circuit Breakers Oil Circuit Breakers SF6 Circuit Breakers Vacuum Circuit Breakers Air Circuit Breakers These are the types or categories of high voltage circuit breakers that are protective electrical devices used ...

  Top 3 powerful categories of circuit breakers every electrical engineer/engineer must know before doing any electrical installation Before we start with our topic of the day, let us take a look at what circuit breakers or breakers are. What is a circuit breaker? circuit breakers are simply electrical protective device that trips off automatically whenever there is an available faulty electric current or leakages flow through an electrical circuit or a particular circuit to keep other circuits intact. In all, there are mainly three (3) powerful categories of circuit breakers and they are moving with their own functions, areas of work, working principles, rating, and many more. Here are our top 3 categories of circuit breakers listed below; Low voltage circuit breakers  Medium-voltage circuit breakers High voltage circuit breakers Low voltage circuit breakers These are the types of circuit breakers that are commonly or popularly known circuit breakers that are designed to be u...
