causes can be anything from a loose connection, equipment failure, wildlife, weather related (wind, flooding, hurricanes, etc.) human error (accidental contact of lines, automobile accident, etc.) high demand, i could go on forever on this one. Since power companies are inter-connected with one another, loads must be maintained and balanced in order to keep service provided, any fault occurring on one of these lines, especially an EHV (extra high voltage) line would immediately force other lines within that grid to compensate for the load unbalance possibly causing those lines(circuits) to lock out as well and in doing so worsening the scenario that much further.

it can be prevented by designing independent system relays in each of the generating units so that when one fails the system will automatically cut off the sudden loss on the transmission this would prevent the domino effect in the circuit

If the power generation system fails it will trip the substations where ever it supplies because of the undervoltage occurring in the system.
