Palm Kernel Oil Cake as an alternative to earth resistance-reducing agent

This paper presents a study on palm kernel oil cake (PKOC) as an earth resistance-reducing agent. The PKOC is a derivative of palm kernel nut after extraction of oil. Significant earth resistance reduction is obtained by means of replacing soil within ´critical resistance area´ of an earth electrode with the PKOC.The properties of PKOC as an earth resistance-reducing agent is investigated. Among the important properties considered are moisture content, moisture holding capacities, pH (acidity) level, and its resistivity. The paper presents and discusses the techniques in the PKOC application and reports the results achieved which demonstrate effectiveness of the PKOC.
