| Zusammenfassung: | The equipment has two switches (S1, S2) such as relay switches, to produce a current path between one of positive or negative terminals and a ground point to determine total resultant insulation resistance during occurrence of isolation errors with arbitrary potential supply. A microcontroller measures the insulation resistance by two successive measurements, where the switch (S1) is closed and the switch (S2) is opened during one measurement, and vice versa in the other measurement. |
