ABSTRACT
Now days the electricity is the main sources for running any devices. The power sources mainly derived from the hydro, thermal or from any methods now uses. So mainly the entire electrical system divided in to 3 different sections. Such as
1. Generation
2. Distributaries
3. Controlling
Generation
For the generation of electrical energy basically the generators are used. The generator is a such machine by which the electricity is generated. One coil moves in between 2 permanent magnet. It is called armature coil. Single phase generators has only one coil. Such generators in which more than one coil is made are called multi phase generators. AC power generated by these is multi phase and multi current supply.
Distributaries
Generally in this process the AC developed by the generator is send to different power grid through the transmission lines. This lines are called as “High Tension (HT)” line. Mainly 33KVA, 11KVA etc are send through over head towers. These are applied to the distribution transformer
Controlling
In system of the project focus on the types of controlling methods are used. They are
Over voltage protection
Under voltage protection
Transformer Protection
Earth fault detection system
