Relay protection distribution network cascade busbar
Literature review has shown that small distribution substations used for medium voltage make use of overcurrent relays to provide busbar protection and large substations make use of differential protection schemes. The relay can also be utilized. These types of protection are typically applied on distribution busbars, where fault current magnitudes are lower and speed is generally less critical than with transmission busbars. In the case of a fault, current on the busbar becomes high, resulting to mechanical destruction which would affect all feeders.
