  4. H-SIP5LB - Description

ANSI 87 Line Differential Protection in SIPROTEC 5. (H-SIP5LB)

  • In this 1-day course, you will learn how to use DIGSI 5 to implement line differential protection as a protection function for monitoring lines and cables using two communication-linked SIPROTEC 5 line differential protections for the SIPROTEC 5 protections. This course focuses on the protection function itself, the settings that can be made and their meanings. It also covers how to practically test this function with an OMICRON test kit and how to handle the online display of the measurements.

Type Face-to-face training
Duration 1 day

    Prerequisites

    • Basic knowledge of the different types of protections as covered in the H-BM or H-BI course. Knowledge of SIPROTEC 5 and DIGSI 5 as covered in the SIPROTEC 5 Basic Course with DIGSI 5.

    Note

      • This course is based on the specific line differential protection within SIPROTEC 5 and contains a lot of theory. Therefore, it is more about following along rather than actively participating on your own or a training PC.
      • If you also want to actively program, we can add a separate practical day where you can work with a line differential protection and a training PC or your own PC, provided the correct software is installed.
      • For testing the line differential protection, a separate day for an additional session of the OMICRON course is recommended.
      • This course can be scheduled for groups of 4 or more people. For more information or special requests, please contact the Power Academy.
