Thus, the organic nature of the PKOC makes it a promising candidate in the earth resistance-reducing agents.
A natural method of reducing earth resistance will be replacing all soil in the effective resistance area with the PKOC. However this method may not in general make sense economically.
Chemical properties of the PKOC were tested in a Soil Research Institute.
Sodium and Potassium were determined by taken 5ml of 1:1 nitric acid concentrate + perchloric acid, 5ml of concentrated sulphuric acid and 1g sample PKOC mixed in a digestion flask and placed on electro-thermal heater for an hour.
To determine the effectiveness of the earth resistance reduction technique, a 100% PKOC was applied as a backfill in a critical resistance radius of earth electrode at selected sites and resistance behavior at the sites monitored over period of three years.
