cascade tripping or failure is a failure in a system of interconnected parts in which the failure of part can trigger the failure of successive part.it means that failure in one part of system may quickly spread into entire system .

cascade tripping occurs for several reason

-when component of grid is over stressed

-generator shut down due to any reason

-if transmission line has too much current following on it, and it will heat up and conductor fails

-when tree are close to transmission line ,electric current from line will produce arc ,and circuit breaker disconnect line .

-natural climate like earthquake ,heavy rain etc ,in which pole are fall down.
