<p>The invention relates to a voltmetric protection module for the occurence of an over voltage neutral-earthing, which may occurs at the consumer in the low voltage network, for the distribution of energy. According to the invention, the module is associated with the maximal voltage electromagnetic trip, and when said over voltage is discovered, the module controls the trip, the supply of the coil thereof from the previously stored energy in a capacitor being allowed, which leads finally to the disconnection of the consumer.</p> |
