Self-test mechanisms measure and verify that power supply voltages are within range, validate checksums of data, check the ability to read and write to memory, ensure that analog-to-digital conversion is correct, and. Protective Relays - Technical Seminar Nov 2016 - Copyright: IEEE 2 Abstract: Protective relays and devices have been developed over 100 years ago to provide "lastline"of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers. Since the basic function of a protection relay is to correctly function under abnormal.
