Misoperations can occur when a relay engineer focuses on one limit without considering the other. This technical article will cover the gathering of information needed to calculate protective relay settings, the setting calculations for the various protective functions, typical generator/turbine withstand times for abnormal operating conditions, and the math associated with various types of impedance elements. If it is more the relay will take more time to operate and vice versa. We are accustomed to providing calculation and relay setting documentation in meticulous detail. In MHO type distance relay the major drawback is that resistive reach is defined by the impedance reach and line angle and hence it is not independently settable in the relay. Time Multiplier Setting used to change the value of operation of the relay.

Consider a simple radial system, which is fed from a single source. the relay by starting at the fault location and working back to the system or starting at the system and working toward the fault. This problem reduces the selectivity of the protection system and causes more than one relay to operate at a time to clear the fault.
