Natural Electric Field Measurements Applied as a Predictive System Against Lightning in Power Systems

Natural electric field, field mill, lightning detection and lightning protection.


This paper presents a study of application the electric field measurement to power systems. The natural earth electric field is disturbed when a thundercloud is present, the evolution of the electrification before a lightning discharge gives enough time to do actions against possible lightning damages. The different orography and nearby objects disturb the natural electric field so that any place has a particular behaviour to evaluate the risk.
