Difference between Contactor and Relay
In this post, we will learn what is the difference between contactor and relay. We use contactor and relay in almost all electrical circuits. We
Power System
Classification of Relays | Different Types of Relays
In this post, we shall discuss different types of Relays like Latching Relay, Reed Relay, Solid State Relay, Differential Relay, Automotive Relay, Timer Delay Relay,
What is a Link Box?
Link box, a box in which a cable sheath braking system is made. Sheath breaking prevents circulating currents and limits induced voltage in the cable
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
Phase Fault Protection
Phase fault protection is used for the protection of induction motors. The protection relay trips the motor in the case of fault. Phase fault protection
What is Type 1 and Type 2 Coordination?
Type 1 and Type 2 coordination defines the short-circuit performance of motor starter components. Set out by the IEC 60947-4-1 standard, these levels describe 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.
Classification of Transmission Line
Classification of the transmission line is based on the voltage, length of the conductor and, types of current flow. We use the transmission line for
What is a Protective Relay? Principle, Advantages, Applications
A protective relay is an electrical device that monitors the voltage and current using CTs and PTs. Thus, the main function of the protective relay
