| Abstract: | Complete protection equipment is very important for the safe and stable operation of high-voltage motor. The paper analyzes a variety of operating state of asynchronous motor, and introduces the principles of time-overcurrent protection, thermal overload protection, motor starting protection, load jam protection of siprotec 4 relay. Combining with a practical example, this paper put forward the protection scheme and explains the requirement of the setting and configuration for these protection functions. |
