Abstract: In order to study the induced voltage problems encountered in the maintenance of live working in distribution networks, theoretical analysis and mathematical calculations are carried out by constructing typical working device scenarios. EMTP electromagnetic transient simulation software is used to build models for verification. The induced voltage magnitude of overhead wires and engineering cables under various working conditions of live working in distribution networks is calculated, and safety measures to be taken during the operation are proposed to ensure that high-altitude workers and ground cooperating personnel avoid the safety risks caused by induced voltage.
