Abstract [en]

It is expensive to measure potential of a high voltage transmissionline by using the ordinary ways like voltage transformers, that is whyit is very important to find a new and a cheap way to measure thispotential. A worked out 3D‐ model finite element is used to estimatecapacitance values of capacitive sensor elements of a tentative nongalvanic voltage sensor for power lines. Appropriate capacitancevalues are one essential input to the algorithm that reconstructs thepower voltages. The sensor is contactless such there is no need forhigh voltage insulation which costs a lot of money. The whole systemcan be moved easily so the measurements can be done in any pointof a line.
