WebbThyristor valve stacks for Pole 2 of the HVDC Inter-Island between the North and South Islands of New Zealand. The man at the bottom gives scale to the size of the valves. Each thyristor valve will typically contain tens or hundreds of thyristor levels, each operating at a different (high) potential with respect to earth. WebbLosses in HVDC thyristor valves are an important economic factor, but their verification by direct electrical measurement is not practical. The origin and method of dissipation of valve losses is described, and alternative methods for valve loss verification are reviewed.
