HV/LV Protection Coordination Studies (Grading)

Appropriate power protection coordination of various elements ensures minimal disturbance in isolation of a fault event. Major shut downs caused by nuisance tripping and poor coordination costs money in lost production and possible spoiled product (as an example, a typical large mine may lose $100k to $150k per hour through an unscheduled power interruption, or about $1,600 to $2,500 per minute !

Through detailed cascading design considerations and system simulations from HV to LV protection coordination studies, achievement of the correct level of protection of each electrical area feeder can provide installation reliability, whilst maximising safety of operation, and minimising any downtime or potential equipment damage during faults.
