Faul voltage-protective device |
摘要 |
The circuit has a switching mechanism (7) that switches off a conductor network on reaching a defined fault voltage between a protective conductor connection (K) and an auxiliary earth connection (H) and an evaluation device (4) for controlling the change between a first operating state for measuring the fault voltage and a second for determining the impedance between the protective conductor connection and the auxiliary earth connection.
