Practical Considerations for Fault Current Split Computation in Power System Grounding
Practical considerations for fault current split calculations are presented. Scenarios involving various transformer types such as delta-star connected, star-star connected, auto-transformer with a delta tertiary, and zigzag grounding transformers are analyzed. It is shown that the fault current going into the grounding system can be overestimated or underestimated if the actual situation is not modeled correctly. Proper examination of various fault current paths involving different transformer types is also presented. The examples given in this paper can be used as a reference by power engineers to carry out fault current distribution calculations accurately and therefore avoiding inappropriate designs in grounding studies.
