Have you ever noticed that Transformers, generators have power rating in kVA but Induction motors and Home appliances have power ratings in kW? Before answering this question “why transformer is rated in kVA not in kW”, we...

In this post we will discuss Definition of Transformer and its working principle A transformer is a static device, it means it has no rotating parts like the other electrical machines such as synchronous machines and induction...
As we have already discussed about working principle of a single phase transformer in the previous section. We discussed that whenever a conductor is placed in a changing magnetic field then according to faraday’s law, an...
In this particular section we will talk about ideal transformer and we will also see it’s phasor diagram with proper steps. We have already seen Transformer and it’s working principle. Definition an properties of...
In this blog we will discuss Ampere-turns relation. After going through this topic we will get an insight of how the mutual flux sets-up in the core of a transformer and also we will see why the mutual flux ɸM remains almost...
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...
A Relay is a sensing device, which is used to sense the faults in the system. If any fault occurs in the system then the relay will send the signal to the circuit breaker to trip the circuit. The same concept applies with the...
