Zinc Oxide Arrester Tester Related Parameters
1. Zinc Oxide Arrester Tester Voltage Protection Level Up: The maximum value of the protector in the following tests: the flashover voltage with a slope of 1KV/μs; the residual voltage of the rated discharge current.
2, zinc oxide arrester tester response time tA: The main reaction in the protector of the special protection element action sensitivity, breakdown time, change in a certain period of time depends on the slope of du/dt or di/dt.
3.Maximum longitudinal discharge current of the zinc oxide arrester tester means the maximum surge current peak value to which the protector is tolerated when a standard lightning wave with a waveform of 8/20 μs is applied to each line and the ground.
4. Maximum lateral discharge current of the zinc oxide arrester tester: The maximum surge current peak value to which the protector is tolerated when a standard lightning wave with a waveform of 8/20 μs is applied between the finger and the line.
5. Zinc Oxide Arrester Tester On-line impedance: refers to the sum of loop resistance and inductive reactance through the protector under the nominal voltage Un. Often referred to as "system impedance."
6. The peak discharge current of the zinc oxide arrester tester is divided into two types: rated discharge current Isn and maximum discharge current Imax.
7. Zinc Oxide Arrester Tester Leakage current: Refers to the DC current flowing through the protector under the nominal voltage of 75 or 80.
8. Data transmission rate of zinc oxide arrester tester Vs: how many bits are transmitted in one second, unit: bps; it is the reference value of the lightning protector in the data transmission system. The data transmission rate of the lightning protector depends on the System transmission method.
9. Zinc Oxide Arrester Tester Insertion Loss Ae: The ratio of the voltage before and after the protector is inserted at a given frequency.
10. Zinc Oxide Arrester Tester Return Loss Ar: indicates the proportion of frontier waves reflected at the protection device (reflective point). It is a parameter that directly measures whether the protection device is compatible with the system impedance.
11. Zinc Oxide Arrester Tester Nominal Voltage Un: The rated voltage of the system to be protected corresponds. In the information technology system, this parameter indicates the type of protector that should be selected. It indicates the effective value of the AC or DC voltage.
12. The rated voltage Uc of the zinc oxide arrester tester can be permanently applied to the designated end of the protector without causing changes in the protector characteristics and activating the maximum rms voltage of the protective element.
13. Rated discharge current of the zinc oxide arrester tester Isn: The maximum surge current peak value to which the protector is tolerated when a standard lightning wave with a waveform of 8/20 μs is applied to the protector 10 times.
14. Maximum discharge current of the zinc oxide arrester tester Imax: The maximum surge current peak value to which the protector is tolerated when a standard lightning wave with a waveform of 8/20 μs is applied to the protector for one shot.
