The working of a protective relay is based on continuous monitoring of electrical quantities such as current, voltage, frequency, and power. A typical protective relay circuit is shown
They provide a visual representation of the electrical and mechanical components of relays, illustrating how they work together to protect power systems from over-current and short circuits.
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
Distance relays, also known as impedance relay, differ in principle from other forms of protection in that their performance is not governed by the magnitude of the
Protection relay is an electromechanical monitoring safety device which senses fault and provide trip signal to the breaker as per set value in LT and HT panel.
Protection relays are used in power systems to maximize continuity of supply and are found in both small and large power systems from generation, through transmission, distribution and utilization of
