摘要: A partial discharge charge amount measuring method includes generating a partial discharge in a sample by applying a voltage from a voltage impressing device connected to the sample, the voltage being higher than a partial discharge inception voltage, continuously measuring and recording terminal voltages of a capacitor connected in series between the sample and a ground at least until a breakdown of the sample occurs by alternately operating at least two data loggers connected to the capacitor at intervals of a predetermined time, calculating an amount of electric charge discharged from the sample and remaining in the capacitor by multiplying a difference in the recorded terminal voltages of the capacitor by a capacitance of the capacitor, and calculating an accumulated discharge amount by accumulating the discharged amount of electric charge at earliest until the breakdown of the sample occurs.

摘要: A noise suppression cable includes an electrical wire, a first magnetic material including a pair of first surfaces formed along an axis direction of the electrical wire and a convex portion projecting from the first surfaces, and a second magnetic material including a pair of second surfaces disposed on a periphery of the electrical wire, the pair of the second surfaces contacting the pair of the first surfaces such that a tubular shape is formed by the first and second magnetic materials. The first magnetic material and the second magnetic material are configured to generate a compression stress in the convex portion of the first magnetic material by receiving an external force so as to reduce a relative permeability of the convex portion.
