Measuring Lightning Grounding Resistance and Analyzing Its Deviation from Truth Value
Yan Li, DU Zhan-hui · Petroleum Engineering Construction · 2009
In allusion to unstable,deviant,even negative reading values of grounding resistance in lightning protection detection for station site or valve chamber,this paper expatiates on the detection methods of lightning protection devices based on the working principle of grounding resistance meter,analyzes several reasons of grounding resistance reading deviation from its truth value,and provides the methods to avoid or reduce the deviations.
