High frequency grounding
Webresistance using a frequency between 500 Hz and several kHz. The 3143 uses a frequency between 100 kHz and 1.5 MHz, close to that of a lightning surge. Therefore, measurement errors can result if the 3143 is used in situations such as the following. In these instances, we recommend using Model 3151. • Electrical grounding or mesh … WebHigh-frequency grounding Leonid Grcev 10.1 Introduction High-frequency and dynamic behaviour of grounding has been the subject of extensive theoretical and experimental …
