Abstract

The breaker has a summation current transformer with a soft magnetic core (2) made of nano-crystalline iron base alloy and with differential windings (4, 5) attached on the core. A relay (3) is connected with a measuring coil (7) of the transformer. The magnetic core exhibits a maximum permeability of more than 350 and a remanence ratio of more than 0.7, where the alloy has a structure, which consists of fine crystalline grains.
