Requirements for Relay Protection Management

Basic protection relay knowledge

Protection is needed to detect electrical faults and abnormal operating conditions. Protection is also needed for protecting people and property around the power network. The protected zone is the part

Life cycle services for protection and control relays

By storing the protection settings and configuration files online through our cloud service, they can be easily restored in the event of malfunction, repair or replacement of the relay.
