Voltage relays perform oversight functions on voltages, and shield a system from a preset threshold being crossed. 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. A voltage protection relay is defined as electrical equipment that is employed for protecting an electrical system against over-voltages, under-voltages, or voltage unbalances.
