Generator Inter Turn Fault Protection: Merz-Price circulating current protection system does not provide protection against turn-to-turn faults (short circuits between the turns) on the same phase winding of the stator…
Static Differential Relay Block Diagram and Working Principle: The differential relay measures the phasor difference between two similar electrical quantities (voltage-voltage or current-current). The rectifier bridge amplitude comparator is the…
Finite Impulse Response Filters Interview Questions and Answers: 1. What are the different types of filters based on impulse response? Ans. Based on impulse response the filters are of two…
Difference between Static Relays and Electromagnetic Relays: The conventional electromagnetic relays are robust and quite reliable, but are required to operate under different forces under fault conditions. This leads to…
Induction Type Negative Phase Sequence Relay: This type of induction type negative phase sequence relay has similar construction as that of an induction type overcurrent relay. The difference lies only…
Voltage Balance Differential Relay: In this voltage balance differential relay arrangement, two similar current transformers are connected at either end of the system element under protection (such as a feeder)…
Thermal Relay Construction and Working Principle: Thermal Relay can operate on the principle of thermal effect of electric current. It consists of bimetallic strips which are used in small sizes…
