Input Output Interfacing Techniques: The most of the microprocessors support isolated I/O system. It partitions memory from I/O, via software, by having instructions that specifically access (address) memory, and others that specifically access I/O. When…
Input Output Interfacing 8085 Microprocessor: Any application of a microprocessor based system requires the transfer of data between external circuitry to the microprocessor and microprocessor to the external circuitry. User can give information to the…
Influence of Static Protective Relays: Influence of Static Protective Relays on the associated equipment like current transformers, voltage transformers, etc,. Let us discuss one by one. Current Transformers: Burdens on current transformers have a great…
Infinite Impulse Response Filters Interview Questions and Answers: 1. Give any two properties of Butterworth lowpass filters Ans. The magnitude response of the Butterworth filter decreases monotonically as the frequency Ω increases from 0 to…
Inductively Coupled Circuits: Inductively coupled multi-mesh circuits can be analysed using Kirchhoff s laws and by loop current methods. Consider Fig. 10.17, where three coils are inductively coupled. For such a system of inductors we…
Induction Type Overcurrent Relay(Non-Directional): This Induction Type Overcurrent Relay works on the induction principle and initiates corrective measures when current in the circuit exceeds the predetermined value. The actuating source is a current in the…
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 in the primary winding provided…
Induction Type Directional Power Relay: This Induction Type Directional Power Relay operates when power in the circuit flows in a specific direction Unlike a non-directional overcurrent relay, a directional power relay is so designed that…
Induction Type Directional Overcurrent Relay: The directional power relay is unsuitable for use as a directional protective relay under short-circuit conditions. When a short-circuit occurs, the system voltage falls to a low value and there…
Induction Relay Torque Equation: In Induction Relay Torque Equation, Two magnetic fluxes Φ1 and Φ2 differing in time phase penetrate through a disc. These alternating fluxes induce emfs e1 and e2 in the disc which lag their…
