Step down transformer is an essential component of many electrical systems. They are used to convert high voltage, low current power into low voltage, high current power. This is important because many devices and appliances require lower voltage than what…
All electrical devices run on electrical power, the consumed energy is measured in terms of watts. the device used to measure consumed power is called a watt meter. to measure three-phase power mainly two methods are used namely two wattmeter…
Voltage control is performed by changing the transformer turn ratio. This is achieved by providing Tapping on the transformer winding. In a tap changing transformer, taping is either provided on the primary or on the secondary winding of the transformer.…
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…
