PARTIAL DISCHARGE MEASURING SYSTEM USING REPEATED IMPULSE VOLTAGES AND PARTIAL DISCHARGE MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a partial discharge measuring system using repeated impulse voltages in which work by a user can be reduced as much as possible.SOLUTION: A partial discharge measuring system using repeated impulse voltages comprises impulse voltage application means, impulse voltage control means, and partial discharge count means. The impulse voltage application means generates a plurality of impulse voltages and applies them to a measuring target. The partial discharge count means counts how many times partial discharge occurs on the basis of a detection signal outputted from partial discharge detection means which detects the partial discharge in the measuring target. The impulse voltage control means controls the impulse voltage application means to apply a specific number of impulse voltages having the same peak value to the measuring target. The partial discharge count means counts how many times the partial discharge occurs each time the specified number of impulse voltages are applied to the measuring target.SELECTED DRAWING: Figure 1
