Checking ground electrode impedance for commercial, industrial
... Most facilities have grounded electrical systems, so that in the event of a lightning strike or utility overvoltage, current will find a safe path to earth. A ground electrode provides the contact between the electrical system and the earth. To ensure a reliable connection to earth, electrical codes ...

Insulation monitor - GMWISO 1.05
... − GMWISO insulation monitors have been conceived for altemators with a largely sinusoidal output voltage. lf altemators with a high relative harmonic content or very asymmetric courses of the curves are used, an influence on the response level is possible. In such cases the usability must be checked ...
