Transistor Use in Static Relay: Transistor Use in Static Relay - In its simplest form, it consists of two pn junction diodes coupled together by a very thin common base,…
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…
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…
Bus Zone Protection: Bus Zone Protection includes, besides the bus itself the apparatus such as circuit breakers, disconnecting switches, instrument transformers and bus sectionalizing reactors, etc. Although bus zone faults…
Gas Actuated Relays: Gas Actuated Relays - When a fault occurs inside the transformer tank gas is usually generated, slowly for an incipient fault and violently for heavy faults. Most…
Pilot Wire Protection Relay: In this case the auxiliary Pilot Wire Protection Relay are provided to carry the information signals from one end to the other. Protective systems requiring the…
Overcurrent Protection of Feeders: Overcurrent relays offer the cheapest and the simplest protection for lines. The maximum load currents must be known to determine whether the ratio of the minimum…
