3 terms and units of measure the following terms and definitions apply to this specification.

3.1 Burst burst

A limited number of clearly identifiable pulse sequences or oscillations of limited duration.

3.2 coupling clip couplingclamp Coupling the disturbance signal to the test line in a common mode without any electrical connection to the line under test, an equipment with specified dimensions and characteristics.

3.3 Coupling network A circuit used to transfer energy from one line to another.

3.4 Decoupling network Used to prevent electrical fast transient voltages applied to the device under test from affecting other devices, equipment, and systems that are not being tested System circuit.

4 Overview

Electrical fast transient burst simulator (hereinafter referred to as burst simulator) includes electrical fast transient bursts , coupled decoupling network and capacitive coupling clips. The pulse group simulator is mainly used to simulate propagation along the power grid or from signal line coupling.

The impact of the electrical fast transient burst on the electronic equipment, and the resistance of the tested electronic equipment the ability of a fast transient burst. Electrical fast transient pulse group generator (hereinafter referred to as pulse group generator) is mainly composed of high voltage
