Abstract
Improvements in devices for detecting the cut of a phase in a polyphase system, which include sensors each of which is associated with one of the aforementioned phases and which are capable of each providing an electrical signal representative of the presence of the corresponding phase, characterized on the one hand, that each sensor is capable of generating a pulse at each alternation of a certain polarity, the same for all, of the phase associated with said sensor and, on the other hand, that they comprise at least one monostable scale whose input is connected to the output of all the sensors and whose tipping time is at least equal to the normal phase difference between two consecutive phases of the system.
