Description

Course Information

This is a two-day course.

Course Base Fees: $1,000 USD

This two-day course provides hands-on application and step-by-step settings guidance for the SEL‑787 Transformer Protection Relay. APP 787 includes applying simplified calculation methods and recommendations and using data from real-world transformers to develop protection settings. Students (in groups of two) will work directly with an SEL-787 Relay to configure system data and determine protection settings.

Audience

APP 787 is intended for utility and industrial protection engineers and power system consultants.


Agenda

Day 1

  • Product Overview
  • Differential (87) Element Settings
  • Commissioning Assistant
  • Relay Logic Settings
  • Through-Fault Event Monitor

Day 2

  • Restricted Earth Fault (REF) Element Settings
  • Overcurrent Elements
  • Overexcitation Volts/Hertz (24C) Element Settings
  • Over- and Undervoltage (59, 27) Protection
  • Frequency (81) Protection Settings
  • Event Report Retrieval and Analysis

Course Objectives

At the conclusion of this course, students can:

  • Use acSELerator QuickSet SEL-5030 Software to read and send settings to the relay.
  • Determine system and transformer winding data and configuration settings.
  • Calculate CT compensation, operate and restraint, and harmonic blocking settings.
  • Test high- and low-voltage CT configuration settings using Commissioning Assistant.
  • Determine settings for through-fault element protection and monitoring.
  • Apply effective protection for REF, overexcitation, undervoltage, and underfrequency.
  • Test settings by observing relay operation after current/voltage is applied.
