Protection for electrical supply systems by directional comparison, involves isolating defect points in very small sections of sound network independently of network operating method

摘要

The method involves isolating defect points in very small sections of sound network independently of the method of operation of the meshed network. Transformers can also be included in this protection system. Protection is guaranteed for a network containing a so-called tripod arrangement or an arrangement with a greater number of legs. Independent claims are also included for the following: a circuit for directional comparison wear protection.
