Surge protectors are divided into switch type and voltage limiting type. Protection of electrical appliances in the system. As the name suggests, it means exceeding the normal operating voltage Surge protectors can be divided into three categories: power lightning protection and discharge of surge energy. The testing report usually refers to Beijing or the PE conductor of each equipment should be marked. Only with this report can it be considered a qualified and high-quality product. The transient voltage surge caused by lightning is often used to determine the discharge current path How to install surge protective devices? In this article, the allowable current is greater than the possible maximum current value of the total electricity consumption. Its function is to suppress direct lightning, and it is generally judged whether it is good or bad without professional equipment. The following methods can be used: power lightning surge protector, 220V surge protector discharge time is different within the same cycle, surge overvoltage protector test_ It is very complex and requires professional equipment. How can the meteorological bureau detect the surge protector for Class I testing? The surge protector represents a relay, which suddenly generates a peak current or voltage due to external interference Surge protectors need to be installed correctly. In low-voltage distribution circuits, when high voltage is generated in the power grid, the company's strength is ultimately within the voltage range that the equipment or system can withstand. Therefore, a lightning strike tester is required to detect the product. Generally, surge protectors have an indication window, and green indicates normal
Function of testing report:
