FIELD: electric engineering.
SUBSTANCE: suggested invention may be used for periodical control of different electric circuits condition. Suggested method of electric circuits testing consists in the fact that measurement facility is connected to load of tested circuit, current value of circuit voltage is measured in idle run mode as well as period of voltage change, at the moment of current value passing through "0" to tested electric circuit reference resistor is connected with resistance of R = 10 Ohm and current value is measured (voltage under load) and its period, by ratio of these values current in the circuit is calculated, afterwards value of circuit total resistance is determined, angle of phases shift between active and reactive voltages, then active and reactive resistances are calculated and module of complex resistance of tested circuit and short-circuit current.
EFFECT: facilitation of measurement process and expansion of functional resources of the corresponding measurement method.
