Abstract :
Functioning stability of a high-speed protection relays of powerful motors within serial commutations during starts essentially depends on current transformers errors, occurred due to DC-currents component flowing. This paper shows the results of analysis of a current transformers group influencing sets in two phases within saturation of one of them in the transient process.
