Abstract

1,216,691. Transformers. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. 19 Jan., 1968 [21 Jan., 1967], No. 3067/68. Heading H1T. An on-load (transformer) tap changing system comprises, for each tap selector, a number of series-connected main switches, as 1, 2, a number of series connected auxiliary switches 5, 6, in the changeover-resistance path, and a voltage dependent resistor 11, 12 in parallel with each main switch. The voltage dependent resistors ensure a uniform distribution of voltage between the series-connected main switches when they are open.
