Protection for Electrical Machines Training System
Squirrel-cage motors were designed to operate with constant loads. Load changes as well as high start-up currents lead to excessive overheating of the motor. Sensors are used to monitor the temperature and the motor current consumption. These activate protective devices such as motor circuit-breakers, protective relays or thermistor relays.

Power Classes Available: 0.3 & 1 kW
Training Concepts:
  • Selection, installation and adjustment of various motor protection systems
  • Motor circuit-breaker
  • Motor protection relay
  • Thermistor protection
  • Influence of various operating modes on the heat build-up of the motor
  • Tripping characteristics of the protective systems
  • Protection against impermissible loads
