Legacy Arc Flash Issues
Legacy Arc Flash Issues
(OP)
Would be interesting to know what transmission utilities are doing about legacy arc flash issues relating to old switchboards that have long fault clearance times due to grading with downstream protection and simple protection schemes such as no bus zone or differential protection.

Certainly most will be providing for remote open/close of the breakers and implementing motor-operated breaker racking.
A lot will depend on the installation (indoor vs outdoor), and the age of the equipment.
