At the start of operation of the device, the voltage at the output of the amplitude detector 3i is zero and the integrator 5 integrates the output voltage of the ammeter detector 1. With increasing / increasing at the output of the integrator 5, the voltage at the output of the amplitude detector 3 also increases; voltage STorq voltage is opposite to the polarity of the output voltage of the amplitude detector 1.
