This paper presents the design and implementation details of a control system that detects an island condition in an industrial facility and executes a multi-tier load shed based on the load-generation balance.

This paper shows that bushings and tap changers are critical as the active part in terms of the root cause of failure. Action steps are described to prevent from failure and ensure electrical power reliability.
