While selecting an induction motor, Motor Duty Cycle must be considered to meet the induction motor application requirement. The duty types are indicated on motor nameplate data by S1, S2… In the absence of an indication of the rated duty…
The types of single phase induction motors are often classified by the names of the starting method used. Like Capacitor start Induction run motor (CSIR), Capacitor start capacitor run induction motor(CSCR), Permanent-split capacitor motor. A standard single-phase stator has two windings placed at an…
Classification of power system Buses In the power system, every bus is associated with four different quantities, real power, reactive power, bus voltage, and phase angle. In load flow, two parameters out of the four are specified and the remaining two…
The procedure of connecting an alternator to the infinite power grid or with a common bus to which the number of other generators are already connected in parallel is known as synchronizing of the alternator. Here we are going to…
The current transformer (CT) is a type of instrument transformer designed to measure high-value current in the power system. The primary has few numbers of the turn of heavy wire, and the secondary of the current transformer has many turns of…
When the current-carrying conductor placed in a magnetic field, it experiences a force due to the magnetic field on the other hand if the conductor moved into the magnetic field an emf gets induced across the conductor as per faraday’s…
The Bridge rectifier is a circuit that converts the alternating voltage into the direct voltage. Rectifiers are made up of diodes and thyristors, to convert AC supply voltage into DC. There are many applications such as electronic circuits, HVDC transmission…
Capacitor is a passive element in a circuit designed to store energy in the form of an electric field. besides resistor, capacitors are the most common electrical components. used mostly in electronics circuit, computers, power system. They are also used…
Some methods of reactive power generation, compansation and advantages of reactive power generation are describe below • synchronous alternators; • synchronous compensators (SC) • static var compensators (SVC) Reactive power using synchronous alternators Synchronous alternators are the main machines…
