which numerical relay is the best for electrical system protection Siemens or ABB or micom relay. we are using most of the relay from ABB and some are from Siemens. I think ABB relay configuration so much difficult but Siemens relay configure is easy. so if you have experience about those relay, please help me to make a decision which relay is the best rely.

 

I think that Siemens Relay are the best, Monostable fast acting electromechanical relay. The design, durability and quality of these relays guarantee their application in high responsibility controls such as power stations, substations, railway, industries of continuous processes (petrochemical, rolling mills, cement and chemical industries).
