A Multi-Sectional Arc Eliminator for Protection of Low Voltage Electrical Equipment

The paper presents a system of two oppositely connected multi-sectional thyristor branches. The system works as a multi-sectional arc eliminator (MSAE), protecting low-voltage electrical apparatus against the effects of an arcing fault. MSAE is designed to serve as a device cooperating with protected and secured electrical equipment. The use of thyristors in the proposed solution allows to obtain a high speed of operation, while multi-sectional...
