In a single phase transformer, there is a primary winding and a secondary winding. The winding to which AC voltage source is connected is known as Primary winding, and the winding to which Load is connected is known as Secondary...
In this section we will discuss about the basic definitions and formulas of electromagnetic field theory which will be helpful for you. This section is very much important for you to understand this subject. x,y,z represents...
In this section we will discuss about definition of control system and types of control system, also about the features of a good control system. As we all know, control system plays a very important role in our day to day...
In this blog we will discuss about the sensitivity of control system. We will also talk about sensitivity function. Later we will derive sensitivity expression for close loop control system as well as open loop control system for...
In this modern era, Switchgear and protection become a important aspect of power system, as demand of electrical energy has increased very much. Electrical energy is much needed in almost every field and purposes like heating...
In this particular section, we will discuss about fuses, types of fuses and their uses, so lets start with the definition. A fuse is a short piece of metal, inserted in the circuit which melts and breaks the circuit when...
As the name itself suggests that a circuit breaker is used to break the circuit. Now, in this particular post we will see that How it breaks the circuit? When it breaks the circuit?and Why it breaks the circuit?I have also...
Oil circuit breakers are very important part of power system, they are responsible to make the system healthy. The classification of circuit breaker is based on the medium which is used to quench the arc. In this section we...
Introduction Air blast circuit breaker is used to interrupt heavy currents and for the extinction of arc with the help of blast of air. Air blast circuit breakers employ high pressure air blast as an arc quenching medium...
In a SF6 circuit breaker, the SF6 gas is used as an arc quenching medium. SF6 gas or sulphur hexafluoride gas has one atom of sulphur and six atoms of fluorine. The physical and chemical properties of the gas are listed...
