I、Overview
According to the new State Power Corporation document (2002) No. 777 "Regulations for Preventive Tests of Power Safety Tools and Equipment", the required methods are used to more scientifically and reasonably complete the power frequency withstand voltage tests for common auxiliary insulation tools such as insulation gloves, insulation boots, and insulation rubber pads.
Auxiliary insulation safety tools refer to those whose insulation strength is not to withstand the working voltage of equipment or lines, but only to strengthen the protective effect of basic insulation safety tools, to prevent contact voltage, step voltage, and leakage current arcs from harming operators. They cannot be used to directly contact live parts of high-voltage equipment. Safety tools in this category include: insulation gloves, insulation boots, etc.
This instrument is mainly used for power frequency withstand voltage tests on safety tools such as insulation gloves and insulation boots, to determine whether these tools meet the conditions of use and ensure the personal safety of workers.
