摘要

The article deals with problems of research and analysis of voltages induced in protective shields of three phase shielded conductor in modes of asymmetric short circuits external to generators of power station. The paper presents a method for calculating the field induced by a power frequency current from a generator at a power station. The calculation is made to determine protective measures to ensure electromagnetic compatibility of power equipment with control and measuring cables connecting measuring current and voltage transformers with microprocessor terminals.
