UR Family Platform

This course is offered:

  1. On customer site, on it's equipment and relays ( Money saver ! )
  2. On our site, using our relays, in small groups ( up tp 5 students ) for best results. ( Most popular ! )

We offer this course as a stand-alone or extended 1-2 days to include an application relay like: D60 and L90 (Line protection), F60 and T60 (Distribution protection), G60 and T60 (Generation protection) etc.


What is my take-home:

The Universal Relay platform including it's hardware, protection elements set, software and communications features is common to all UR family members. . The course will review the UR's specifications, hardware selection, installation and wiring procedures used in modern substation protection, control and data communication.

This course is applicable to all the UR models: B30, B90, C30, C60, C70, D30, D60, F35, F60, G60, L90, N60, M60, T35, and T60.

Who should attend?

  • Electrical engineers new to the UR family.
  • Electrical engineers refreshing their knowledge for substation design and maintenance
  • Managers, coming to understand better the protection using any UR relay
  • Electrical maintenance teams personnel

Recommended Prerequisites

  • Electrical professional credentials
