An induction generator is also called an asynchronous generator. An induction machine can work as a generator. For working as a generator initially, the three-phase induction motor is started as a motor. During motoring operation, it draws reactive volt-amperes from…
The dielectric strength of transformer oil is known as BDV or break-down voltage. A Transformer Oil BDV test is performed to find the dielectric strength of transformer oil. BDV is the minimum voltage to withstand the capacity of transformer oil…
Grounding wire running over the tower or substation provides good protection to the electrical system against direct lightning stroke but they fail to provide protection against traveling high voltage or current waves that reach terminal equipment. The lightning arrester or…
A fuse is a small wire connected between two terminals that are mounted on an Insulating base and connected in series with a circuit. A fuse is the simplest and cheapest current interrupting device used to protect equipment from overload…
What is DOL Starter? DOL Starter is the simplest and cheapest method used for starting a three-phase induction motor. DOL starter is used for up to 5 HP motors. this starter is more popular due to the low price. Different starting methods…
Function and Principles of Synchroscope Synchronizing A synchroscope is an essential device used for synchronizing AC power systems. It measures and displays the frequency difference and phase angle between two AC power sources. The device typically features a dial with…
A star delta starter is a type of motor starter that is used to control the starting and stopping of three-phase induction motors. It is commonly used in industrial applications where motors of large power ratings are used. Here is…
Types of insulators are used in an overhead transmission and distribution line to provide insulation to power conductors from the ground and tower or supporting structure. like Pin type of insulators, Suspension, and Strain type insulators. There are 5 types of insulators…
The armature will draw a very high current due to the small resistance of the armature winding to avoid this heavy starting current 4 Point starter is used. Here we are going to discuss the 4-point starter it’s working principle and…
What is Soft Starter? Soft Starter is starting device, used for the acceleration, deceleration, and protection of the three phase electrical induction motors through the controlling applied voltage to 3 phase motor.Induction motor is the most frequently used motor for…
