Overcurrent Protection Relay in Power System: The technique of Overcurrent Protection Relay in Power System is still widely used as a means of detecting faults on distribution system and on…
Basic Elements of Static Relay: The basic elements of a static relay are namely, Input Element: Mixing circuits are needed to sum the input signals in a convenient form. Semiconductor…
Hall Effect Relay Circuit: Hall Effect Relay Circuit is utilized to give a phase comparator. The effect is very predominant in certain semiconductors such as indium arsenide, indium antimonide, indium…
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…
Transductor Relay (Magnetic Amplifier Relay): Transductor Relay - Since relays now have to perform much more complicated functions, many types tend to become very complex mechanically, and hence costly, to…
Electronic Relays: Electronic Relays - These were the first to be developed in the series of static relays. They date back to early 1928 when Fitzgerald presented a carrier current…
Static Relays Basics and Classification: A Static Relays Basics refers to a relay in which the measurement or comparison of electrical quantities is done in a static network which is…
Percentage Biased Differential Relay: Percentage Biased Differential Relay - In order to avoid undesirable operation on heavy external faults due to CT errors and ratio change as a result of…
