Secondary protection of power plant relay protection

POWER SYSTEM PROTECTION

Backup protection relays provide secondary protection in case primary protection relays fail to operate or if there''s a delay in their operation. They help ensure the reliability and safety of power systems.

Power System Protective Relays: Principles & Practices

As the protected components of the electrical systems have changed in size, configuration and their critical roles in the power system supply, some protection aspects need to be revisited (i.e. the use of
