Analysis Of The Core Parameters Of Surge Protectors

Maximum discharge current Imax: The maximum peak surge current the protector can withstand when a standard lightning wave with a waveform of 8/20μs is applied once to the surge protective device.

Voltage protection level Up: The maximum value the protector can withstand in the following tests: sparkover voltage with a slope of 1 kV/μs; residual voltage at the rated discharge current.

Response time tA: This mainly reflects the operating sensitivity and breakdown time of the special protection element in surge protector. Its change over a certain period of time depends on the slope of du/dt or di/dt.

Data transmission rate Vs: Indicates the number of bits transmitted in one second, in bits per second. It is a reference value for correctly selecting a lightning arrester in a data transmission system. The data transmission rate of surge protection device depends on the system's transmission method.

Insertion loss Ae: The voltage ratio before and after the protector is inserted at a given frequency.
