Abstract

247,424. Rogers, F. H., (Zera). April 3, 1925. Transformers. - An apparatus for calibrating supply meters comprises a transformer a having subdivided primary and secondary windings p, s, the sections of which can be connected in series or parallel by switches b, c, d, and a variable secondary resistance e contained in a small closed casing fitted with sockets i to which the meter z to be calibrated and a standard watt-meter w are connected by plugs g, h.
