HIGH VOLTAGE INSTRUMENT TRANSFORMER AND METHOD FOR PARTIAL DISCHARGE RECOGNITION

摘要

The present invention relates to a high voltage instrument transformer (1), with measuring assembly (3, 4) and isolator (5), and with at least one sensor (9) for partial discharge measurements. A method for partial discharge recognition in high voltage instrument transformers (1) according to the present invention comprises a detection of a signal from at least one sensor (9) for partial discharge measurements, particularly a Transient Earth Voltage sensor.
