Earth Fault Protection

COURSE NO: E03-038
Earth Fault Protection
Course Highlights

This online engineering PDH course describes protection principles for effective reactance, high resistance and resonance grounded electrical systems. The presented details cover issues related to ground protection technical implementation.


Fault statistic suggests that earth faults are dominating fault type. Therefore, earth fault protection is of great importance in electrical networks. The type of the used earth fault protection depends primarily on the type of the earthing method.


This 3 PDH online course is suitable for electrical engineers and technicians with a desire to understand the fundamentals of earth fault protection. Upon successful completion engineers will be able to address key earth fault protection concepts, terms and schemes.
Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Learning about solidly earthed system fault protection
  • Learning about restricted earth fault protection (REF)
  • Understanding directional comparison schemes
  • Learning about current reversal
  • Learning about reactance earthed system fault protection
  • Learning about high resistance earthed system fault protection
  • Learning about resonance earthed system fault protection
Course Document
In this professional engineering CEU course, you need to review the document titled, “Earth Fault Protection” by Velimir Lackovic, Char. Eng., which is based on widely used generator protection theory and practice.
