Fault statistics suggests that earth faults are the dominating fault type. Therefore, earth fault protection is of great importance in electrical networks. The type of earth fault protection used depends primarily on the type of earthing method. This course describes protection principles for solidly (effectively), reactance, high resistance and resonance grounded electrical systems.
This 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
Upon completion of this course, participants will be able to:
- Describe fault protection for solidly earthed systems.
- Explain restricted earth fault (REF) protection.
- Describe directional comparison schemes.
- Explain current reversal in earth-fault protection.
- Describe fault protection for reactance-earthed systems.
- Explain fault protection for high-resistance-earthed systems.
- Describe fault protection for resonance-earthed systems.
Certificate of Completion
You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 20 questions. PDH credits are not awarded until the course is completed and quiz is passed.
