Resonance Grounding
Resonance Grounding
(OP)
What are the advantages and disadvantages of resonance grounding and when it is applied? I have encountered the same description in an IEEE handbook but it simply says..it very complicated to use. Are there any info on this? I am curious.

You could also try Google for arc suppression coil or petersen coil.

There is another application,used in some countries.A neutral reactor is connected to the neutral of three phase shunt reactor -I am told for reducing arcing on single phase to line fault. How this compares with ARSC?
You have said some users allow the line fault to continue indefinitely.Then will not the supply in that line get affected?

RE: Resonance Grounding
reactance current = due to the tuneable reactor
capacitance current = due to line capacitance
Other downside for this kind of grounding is the fact that the reactor has to be tuned everytime the system changes. And that faults on different parts of the system may result in different values of fault-current.
One reference given in the Green Book (142-1991 GREEN BOOK IEEE Recommended Practice for Grounding of Industrial and Commercial Power Systems):
AIEE Committee Report, "Application of Ground Fault Neutralizers,"
Electrical Engineering, vol. 72, July 1953, p. 606.
Regarding your last question: Ain't you refering to resistors? With reactance grounded systems (not resonant grounding) there can be problems with power frequency overvoltages under arcing earth fault conditions. The mining industry in South Africa experienced such problems in the mid 1970s, if I remembered correctly a Pretorius-guy where involved with it. Will have to check through some of my papers.
