Relay Protection Fundamentals (URPF)
What
is my take-home:
This corner-stone Utility Relay Protection Fundamentals (URPF) course is a must
have for all engineers who enters into the Protection & Control field and
electrical technicians.
It
is the most popular course and the most comprehensive elevating
understanding of the principles of protection relaying and applications.
