Abstract

180,662. MÚtallurgique Electrique. May 21, 1921, [Convention date]. Cut-out arrangements.-Where a series of relays adapted to operate in sequence is employed, each relay is energized from a current transformer whose core is adapted to become saturated so that a maximum is fixed for the induced current. This prevents a greatly excessive current operating all the relays simultaneously. Reference has been directed by the Comptroller to Specifications 100,892 and 102,335.
