Static relays are low burden, more accurate, low weight, easy testing & having higher range of setting than EM relays. Cost is more than EM relay.
Numerical relays are micro processor based relays and having the features of recording of parameter used as disturbance recorder flexibility of setting & alarms & can be used one relay for all type of protections of one equipment hence less area is required. Wide Range of setting, more accurate, Low burden hence low VA of CT is required which minimize the cost.
