Abstract
A PD (partial-discharger) measuring device to improve on-site measurements has been developed that is based on a digital filtering algorithm. The adaptive filter reduces periodic interference, e.g. from broadcasting stations. The filter principle is based on a fast Fourier transform that it suppresses external sinusoidal disturbances effectively. Even partial discharges with an apparent charge less than the basic interference level can easily be detected.<>
