Abstract
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 curve, a fault signal being generated when a tolerance band placed around the echo difference curve is exceeded. In this way, a monitoring method is achieved which is nearly independent of the sharply fluctuating ground conductance, which has a higher range with simultaneously lower dispersion of the echo, which radiates less electromagnetic energy and which requires no additional decoupling elements.
