Protection Grading

Protection Grading is an important requirement in the electrical network to ensure discrimination and selectivity of downstream faults.
It is of vital importance that the protection system on any distribution network operates swiftly, correctly and that all the various relays grade to ensure that in the event of a fault the affected part of the network is isolated swiftly. The speedy operation of the protection system minimizes the stress which the network is subjected to and limits the damage which can be caused to the network resulting from the flow of fault current.
