Контроль ізоляції в системах електропостачання з ізольованою нейтраллю напругою до 1000 В

Abstract

In the work, a study of existing insulation control methods in power supply systems with an isolated neutral voltage up to 1000 V was conducted. The proposed method is based on the principle of creating a certain asymmetric mode, involves alternate testing of the network phases, during which the voltage on the tested phase, the current in the choke and the power are measured.
