ABSTRACT:
A method and device for detecting and localizing fault in electrical installations includes performing partial discharge measurements and high-frequency measurements at least at one location in the electrical installation and optionally in all phases, selectively comparing the measurement values with each other and with calibration signals, drawing conclusions from the measurements regarding the location and the type of the fault, selectively continuously and periodically performing the measurements at least at three measuring points while the installation is in operation, simulating the electrical installation in a computer as a high-frequency network, while simulating fault with the signals originating therefrom at the measuring points, comparing any measurement values which indicate fault with the simulated signal values for different fault types and fault locations, and determining the type and location of the fault from the simulated signal values which best agree with the measurement values and from the corresponding simulated fault.
