Its core function is to apply a high voltage (typically several hundred to several thousand volts) to detect the resistance value of insulating materials, determine whether they meet safety standards, and prevent accidents such as electric leakage, short circuits, or even fires caused by insulation failure. It is widely used in fields such as electric power, electronics, chemical engineering, and construction, and is one of the core tools for electrical safety testing."}
