Is relay protection debugging difficult

Explore why relay protection testing is becoming more complex with IEC 61850 systems, and discover practical steps to streamline your protection workflows. If you've been in protection testing for a while, you'll know the job has changed – not always for the better. Where once you could trust. In the actual operation management process, it is required to form a different debugging and management scheme with the corresponding relay protection device, and regularly check its operation status, so as to achieve the concept of fault detection and timely treatment.
