By a self-transformer with voltage regulating device, characterized by being constituted by a self-transformer, which carries in its housing a good eye, so that it can indicate a white light, or red light, with automatic voltage regulator and relays , for the combination of colors, replacing the voltmeter as the white light indicates normal current and red light, bad contact or excessive current flow, because when turning a hand when starting the auto-transformer , due to the effect of exceeding the regulated voltage, said device is disconnected, since the regulator pin jumps when the current is broken.
