一般說明

The Electrical Machines Relays Protection Unit, "AEL-EMRP" has been designed by EDIBON to study the elementary protections for three phase squirrel cage induction motors.

In order to study the behavior of the electrical machines protections, this unit consists of a three-phase induction motor of squirrel cage coupled to a servomotor. On this way, the user can control the servo machine and modify the loads condition of the motor to be studied. With the servomotor the user can increase the current consumption by the induction motor and provoke overcurrent and overheating to study the electrical protections performance.
