The lightning protection surge protector, commonly known as the SPD (Surge Protective Device), is a critical piece of equipment used to protect electrical systems and equipment from lightning strikes and overvoltage effects. Working principle: The lightning protection surge protector mainly protects the connected equipment by transferring the overvoltage or overcurrent from the power line to the ground. It contains nonlinear components such as varistor MOV. Under normal voltage, these components have high impedance. Under overvoltage conditions, they will quickly conduct and transfer the surge energy to the ground. Additionally, it may also include discharge tubes. Other components may also be added to enhance its performance. Performance indicators: Key performance indicators include rated discharge current (Imax), nominal discharge current (In), voltage protection level (UP), and response time.
