UR Advanced Applications

What is my take-home:

This course comes to expend on the UR family platform and teach the Electrical engineer the depth of the applications provided by the UR relay.

Traditional agenda is provided bellow. ( G60, F35/60, B30/90, T35/60, D30/60, L30/90 )

We will tailor into the course content to fit your specific relay needs. (M60, C30,C60, C70, N60)

Who should attend?

Electrical design engineers System managers

Senior protection engineering staff responsible for relay selection and overall network design.

Recommended Prerequisites:
Industrial/Utility Relay Protection Fundamentals course
UR Family Platform level-1course
Recommended Duration
5 days
