Abstract

An apparatus for connecting a pulsating voltage across a winding upon such inspection of an electric machine, in particular a three-phase machine, as aims at detecting a stator and/or rotor winding fault, is provided with a current source (2) and an oscillator (1) connected to aid current source via a switch (3). An ammeter (6) is connected in one output (4) of the oscillator (1) which is adapted to supply a pulsating voltage of variable pulse width, said pulsating voltage being intended for connection across the said winding, and said pulse width being variable to provide a suitable deflection of the ammeter (6) when the pulsating voltage is connected across the winding. <IMAGE>
