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.
