In and Imax 8/20 µs Waveform of Type 2 Surge Protective Device SPD
Sensing the Surge: When a surge occurs, the voltage in the system rises above the normal operating level. The Type 2 arrester is connected parallel to the electrical system, constantly monitoring the voltage.
Redirecting Excess Energy: Once the type 2 SPD detects that the voltage has exceeded a predefined threshold (the clamping voltage), it activates and quickly diverts the excess energy to the ground, preventing it from reaching connected devices.
Suppressing the Voltage Spike: The type 2 SPD reduces the magnitude of the overvoltage by limiting it to a safe level for the electrical installation and equipment.
Resting State: After redirecting the surge energy, the type 2 SPD returns to its normal state and continues monitoring for any future surges. It doesn’t interrupt the power supply during normal operation, allowing the system to function as usual.
