DEVICE FOR THE PREVENTION OF SERIOUS FAULTS IN ELECTRICAL MAINS SUPPLY NETWORKS |
摘要 |
The invention relates to a device for the prevention of serious faults in electrical mains supply networks by spectral analysis of the network voltage. The spectrum determined by a voltage A/D converter and a spectral analysis device is subjected to a classification by frequency intervals. The values for the frequency interval classes are correlated in the comparator with frequency interval class reference patterns for corresponding determined faults.
