Operation, maintenance, and field test procedures for protective relays and associated circuits (photo credit: Omicron) The protection circuits
These cover the mechanical performance of relay such as tendency to vibrate, effect of shocks, balancing of rotor, endurance tests, deviability of springs etc. Special test equipment is necessary to
Protective relays are devices designed to detect electrical faults and initiate actions that protect both the equipment and the integrity of the power system. As an electrical technician working within the
To test the protection function with injected signals (current and voltage) PC controlled electronic test equipment is available nowadays which provides almost fully automated test sequences.
Since type testing of a digital or numerical protection relay includes software and hardware testing, the type testing procedure is very complex and more challenging than a static or electromechanical relay.
Okusha Engineering has since become the service provider of choice in the Electrical Protection Business, working at various sites across South Africa and
