APP 700G: SEL-700G Generator Protection Relay


This course is designed for utility and industrial protection engineers and power system consultants.

This two-day course provides hands-on application examples and step-by-step settings guidance for the SEL-700G Generator Protection Relay. This activity-based course includes applying simplified calculation methods and recommendations, and using data from real-world generator examples to develop protection settings. Students (in groups of two) will work directly with an SEL‑700G Generator Protection Relay to configure system data and determine protection settings.


Day 1
  • Product Overview
  • Differential (87) Element Settings
  • Stator Ground (64G) Element Settings
  • Field Ground (64F) Element Settings
  • Negative-Sequence Current Unbalance (46) Element Settings
  • Overexcitation Volts/Hertz (24C) Element Settings
Day 2
  • Synchronism-Check (25C) Element Settings
  • Loss-of-Field (40) Element Settings
  • Restricted Earth Fault (REF) Element Settings
  • Optional: Ground Differential (87N) Element Settings
  • Neutral Time-Overcurrent (51N) Element Settings
  • Optional: Voltage-Restraint Time-Overcurrent (51V) Element Settings
  • Reverse Power (32) Element 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
  • Enter system and generator data into configuration software
  • Set two-zone stator and field (rotor) ground detection schemes
  • Determine effective settings for differential, current unbalance, overexcitation, and loss-of-field protection
  • Protect small generators and large (387 MVA, 22 kV) unit-connected generation systems
  • Synchronize generator-breaker close operations
  • Verify relay tripping and protection for various faults and abnormal conditions
  • Apply IEEE standards and formulas to determine a range of protection settings
