To monitor an electrode lead composed of two lines in a bipolar HVDCT system, a balanced-to-ground pulse formed from an unbalanced-to-ground pulse in push/pull mode is fed into the lines and an actual echo curve is recorded from the echo signals and compared to a dynamic target echo
A method and a device for detecting and correcting a saturated current profile of a current transformer in a particularly simple and reliable way, initially uses a number of logic inquiries derived from sampled values of the present current signal profile to detect a start of saturat
