ABSTRACT:
The present invention relates to a protection device for detecting at least one faulty phase in an electrical network. The device comprises a band exclusion filter for each phase for filtering away the signals which have the same frequency as the nominal frequency of the network, amplifiers, rectifiers and peak value forming means for each phase. In addition, the different phase signals are fed to a function element which delivers a signal to a level and comparison device for each phase, where the signal is compared with the signals in the respective phase.
