.Explain Explain with neat diagram the application of Merz price circulating current principle for the protection of alternator. 10.Write the theory of induction relay torque. IEEE Transactions on Industry Applications, vol. PART-B *What is a protective relay? Is the protection in which the fault occurring in a line will be cleared by its own relay and circuit breaker. Lewis Blackburn, Protective Relaying: Principles and Applications, Third Edition retains the fundamentals of protection relays and power system protection while incorporating new developments in the field. Describe the operating principle, constructional features and area of applications of reverse power or directional relay. .Describe the construction and working of a Buchholz relay. Protective Relaying Theory and Applications By Walter A. Discuss the recovery rate theory and energy balance theory of arc interruption in a circuit breaker. .Derive the equation for torque developed in an induction relay. In practice, the transformer would need to be derated to . Explain its function in an electrical system. Continuing in the bestselling tradition of the previous editions by the late J. *Explain the functional requirements of protective relay. A non unit system is a protective system which is activated even when the faults are external to its protected zone. G., Bishop A., Effect of voltage harmonics on the operation of solid-state relays in industrial applications. As before, the calculations are based on the theoretical values from Figure 1.
