APPAREIL ET PROCÉDÉ PERMETTANT DE METTRE EN OEUVRE DES TESTS INSTANTANÉS DE COURT-CIRCUIT SUR UN GÉNÉRATEUR SYNCHRONE POLYPHASÉ

摘要

An apparatus for performing instantaneous short- circuit tests on polyphase synchronous generators includes : a switch (5) having first terminals (5a, 5b, 5c) connected to respective stator terminals (2a, 2b, 2c) of an electric generator (2) and second terminals (5d, Se, 5f) connected to one another; an acquisition module ( 18 ), configured to acquire electric signals (VR', VS', VT' ) representative of output voltages (VR,VS, VT) on the stator terminals (2a, 2b, 2c) of the electric generator (2), respectively; and a processing module (20), configured to cause the switch (5) to close as a function of the output voltages (VR, VS, VT) of the electric generator (2).
