FIELD: electricity.
SUBSTANCE: tuning device, comprising amplitude or phase detector of unsymmetry vector, additionally includes an element for measurement of own frequency of controlled circuit, which determines signal of arc-quenching reactor inductance control. Device arrangement is provided with auxiliary generator of artificial excitation pulses, and it may also be connected into circuit of controlled loop.
EFFECT: increased accuracy of tuning in wide range of control and expansion of area of application of device, which is insensitive to unstable vector of unsymmetry and may be operated in networks with reduced Q-factor.
