Abstract :
The principles of how DC fields can be measured using an isolated probe coupled by fiber optics to a separate receiver are discussed. The construction of some practical systems is described, with attention given to induced current, voltage, power, and dipole systems. The electric fields around a full size wall bushing energized to 600 kV in rain were measured. The results of this measurement and other measurements are presented, demonstrating the usefulness of isolated DC field measurements
