ABSTRACT OF THE DISCLOSURE The invention relates to a method for overvoltage pro- tection of an HVDC transmission line system in which AC is supplied to the valves of a converter to convert the AC to DC. A surge arrester and resistor are connected on the DC side of the converter. The method includes supplying control pulses to the valves of the converter for operation thereof. The presence of overvoltage in the converter is detected by actuation of the surge arrester. The control pulses to the valve converter are blocked in response to actuation of the surge arrester to produce a misfire of the valve and zero output of the converter. Thus, the surge arrester becomes deactuated and the control pulses are then again supplied to the converter valves and the converter resumes normal operation.
