The digital protective relay or numeric relay is a protective relay that uses a microprocessor to analyze power system voltages, currents or other process
Using the advanced microprocessor technology the relay meets the most demanding reliability and availability specifications, and it is intended for application in distribution and industrial plants.
The PCS-9613 relay is a current differential protection and overcurrent protection, control and monitoring unit with auto-reclosing function for distribution feeder lines in solidly grounded, impedance
OverviewTypes according to constructionOperation principlesRelays by functionsPower source
Electromechanical relays can be classified into several different types as follows: "Armature"-type relays have a pivoted lever supported on a hinge or knife-edge pivot, which carries a moving contact. These relays may work on either alternating or direct current, but for alternating current, a shading coil on the pole is used to maintain contact force throughout the alternating current cycle. Because the air gap between t
The types of protective relays that exist are overcurrent, electromechanical, directional, distance, pilot, and differential relays. The circuit diagram of the protective relay is made up of current
