Увод
Conductive noise is electrical noise spreading from various paths. It spreads from the transient overvoltage (lightning strike surge), electrostatic, high-order harmonics, итд. through the power supply, signal and grounding cables. Такође, noise generated by magnetic fields is called “radiation noise”.
Проблем
- Equipment malfunction or damage
- Receiving problems with TV and radio signals in the neighborhood
Анализа
Conductive noise is often high frequency noise. As such, the following measurement scan be effective. Додатно, you can cover up to 100MHz of frequency by using HIOKI Model 3144-20 Noise Search Tester or 3145-20 Noise HiLogger.
- Пролазни пренапона – Generated by lightning strikes, switching from generation to consumption, grid switching, итд. This can cause malfunction to equipment and solar power generation systems, итд.
- Секундарне фреквенције, Високи реда хармоници
- Таласни облик изобличења
