| 摘要 |
A combined measuring and detection system which comprises an electronic evaluation unit (4) for analyzing a broad frequency spectrum of measured quantities and one or more measuring devices for measurement of one or more of a magnetic field, an electric field, a current, and a voltage (22, 23). The measuring devices (22, 23) are operatively connected to the electronic evaluation unit (4), which is provided with at least one frequency splitter for dividing the measured quantities into a low frequency component and into a high frequency component. Low frequency components are used for measurement and protection analysis and high frequency components are used to detect partial discharges activity. |
