Title:
【発明の名称】広域パスバンドを有する導体電流強度測定用装置
Document Type and Number:
Japanese Patent JP2001521629
Kind Code:
A
Abstract:
The current to be measured (I) passes in a conductor (1) enclosed with a Rogowski coil (4) and in the proximity thereof are arranged several magnetic field detectors (3). The sum of the signals from these detectors, formed in the device (2), and the signal supplied by the Rogowski coil are applied to a signal processor (7). The processor (7) comprises, for example, a first order delay device connected to the Rogowski coil output and means for amplifying/reducing the signals followed by adding means, the delay time constant and the amplifying/reducing factors being selected so that the device output (8) signal is proportional to the intensity of the current to be measured in a very wide frequency range, i.e. from 0 to more than 10 MHz.
