Different Faults in Three Phase Induction Motor & their Remedies
This article describes different types of faults and problems in 3-phase induction motor & their remedies. The induction motor is a very robust, reliable, and
Electrical
Impedance Triangle
Impedance Triangle is a right angle triangle whose sides represent the impedance. The base, perpendicular and hypotenuse represents Resistance, Reactance and Impedance respectively. It is
Nominal T model of a transmission line
Nominal T model of a medium transmission line has two components- series impedance and shunt admittance. In this post, we shall discuss the nominal T
What is a Step-up & a Step-down Transformer? Definition
Definition-step-up and step-down transformer: Step-up transformer step-up the primary voltage. On the other hand, the step-down transformer step-down the primary voltage. Thus, the secondary side
Phase Fault Protection
Phase fault protection is used for protection of induction motor. The protection relay trips the motor in the case of fault. We can call the
What is Winding Factor?
Definition: Winding Factor is the product of the Distribution factor (Kd) and the coil span factor (Kc). The main purpose of the winding factor is
3 Phase Induction Motor | Definition And Working Principle
3 Phase induction motor converts electrical energy into mechanical energy. The induction motor is the most popular choice. In industries, about 80 % of motors
What is Type 1 and Type 2 Coordination?
What is Type 1 and Type 2 Coordination? Type 1 and Type 2 coordination indicates the criteria of short-circuit performance of motor starter components. The
What is Through Fault?
Through fault occurs outside of the protective zone. In other words,occurrence of the external faults outside of the equipment protective zone is called through fault.
Single Phase Preventer Working Principle | Induction Motor Protection
In this post, we will learn the single-phase preventer working principle. We use a single-phase preventer to protect the induction motor from a single phasing fault.
