Lightning surge current
WebIt is important to understand the difference between class 1 current (lightning) and class 2 current (surge). The following figure 2 illustrates the difference which lies in the time duration of the transient which will determine the power or amount of energy in the transient.

WebWhen lightning strikes the ground or an object on the ground, the discharge occurs in and along the ground surface (not deep into the ground). This creates a dangerous and potentially deadly ground current near the … WebThe peak current per line needs to be considered when selecting the surge current rating of components within the PD, including any surge protection devices (SPDs). The path of the surge needs to be understood to determine whether the component will see the current associated with one line or an additive current associated with multiple lines.
WebThis varies by insurer and how the damage occurred. Renters insurance typically covers damage caused by power surges that result from a lightning strike. Power surges that are generated by an artificial current may or may not be covered. Ask your agent or check your policy to see if certain types of power surges are excluded from coverage. WebApr 12, 2024 · Selecting a surge protection device is straightforward. The first thing is to remember the value of what you are protecting. Since the electronics in RVs are costly to repair or replace, err on the side of too much protection rather than not enough. For an RV with 30-amp connections, a minimum of 3000 joules and 6500 amps of maximum current …
Webthe lightning strike, while the security camera will be exposed to a much lower overvoltage event as the surge has largely dissipated by the time it reaches the camera. Surge current To calculate the surge current, divide the voltage waveform by the impedance of the connection between the originating event and the system.
