High voltage direct current (HVDC) converter stations generate radio frequency (RF) electromagnetic (EM) noise due to valve firing. The noise propagates into the AC and DC switchyards and along their corresponding transmission lines. This noise can affect the performance of adjacent communication, control and computer equipment, and can interfere with carrier system operation. Therefore, it is important to measure, predict, and mitigate the EM noise and interference. Information related to major station equipment impedance values in a broad frequency range is important for EM noise calculations. All power system components can be characterized as frequency dependent impedances. The paper describes the instrumentation, improved measurement procedures, a systematic measurement program, and equipment representation concepts. Transformer related examples are used to illustrate the more relevant features of the paper.
