Abstract: The objective of the project is to design protection panel for three phase induction motor using numerical relay .Our project is based on the protection of three phase induction motor. A modern numerical motor-protection relay is designed to offer a wider range of function and more user-related possibilities for motor protection, supervision and control. The numerical relay can perform a full range of motor- protection function based on load current such as thermal overload, short-circuit, excessive start time, locked rotor, unbalanced, earth fault, loss of load. This protection panel includes a combined protection approach for three phase induction motor such as over current, short circuit, phase unbalancing ,earth fault and also single phasing fault.

Keywords: Numerical relay, three phase induction motor, overloading, phase unbalancing.
