High Resistance Grounding

What are the pros/cons of high resistance grounding versus solid grounding and low resistance grounding? What is the preference for different applications? What complications does high resistance grounding introduce in drive system applications?

Thank you.

Hi Chiv,

I found a Comparative Benchmarks for Various Grounding Methods in the internet this is the link http://www.postglover.com/highcompare.html

Hope it helps,

High resistance grounding reduced the magnitude of transient over-voltages, improved system and equipment fault protection, and safety for personnel during installation and maintenance. The main disadvantage of this system is the expenses and maintenance of high grounded facilities.

Solid grounding and low resistance grounding produces ground fault current which damages the equipments. It has an ease of maintenance since there are few components to be considered but it gives more electric-shock hazards to personnel that is caused by stray ground-fault currents.

You can have more detailed information with National Electrical Code

Good Luck
