Abstract
An electric field sensing system is characterized so that a signal processor may derive an output representative of an electric field intended to be measured, particularly established by high voltage on a power line, with enhanced accuracy. Characterizing parameters may be derived from signals representative of a pair of light waves derived from a light wave exiting an optical electric field sensing element in a electric field sensing head spatially positioned in the high voltage environment.
