Relaxation Time, Collision Time and Mean Free Path: The relaxation time is closely related to the mean time of flight between collision and also to the mean free path of…
Measurement of Physical Quantities: Measurement of Physical Quantities is given by Displacement Measurement Strain Measurement Force Measurement Torque Measurement Pressure Measurement Temperature Measurement Water-Level Indicator Measurement and Display of Speed…
No Load Test of Induction Motor: In this No Load Test of Induction Motor, the motor is run on no-load at rated voltage and frequency. The applied voltage and current…
Transistor Relays: These are the most widely accepted type of static relays, so much so that when we say static relays, we can safely infer transistor relays only. The transistor…
Prime Mover Protection: In the event of prime-mover failure the machine starts motoring meaning thereby that it draws electrical power from the system and drives the prime-mover. This condition imposes…
Single Phase Directional Relay: Single Phase Directional Relay - The general Eq. (4.8) suggests that for directional control the individual torques, viz. K |A|2 and K′ |B|2 should be eliminated. Considering a…
Relay Design and Construction: The Relay Design and Construction is normally divided into the following stages: Selection of the operating characteristics. Selection of proper construction. Design of the contact movement…
