FIELD: physics; electricity.
SUBSTANCE: two consecutive voltage measurings are carried out at connection of measuring body with different input resistances, control resistor and divider between general minus busbar of radiants and case. The equivalent resistance and voltage between the minus busbar and the case are calculated on the measured two values of voltage calculate taking into account divider and the control resistor, then the equivalent resistance of voltage between the minus busbar and the case is calculated taking into account the control resistor after that calculate insulation resistances of busbars. The calculated insulation resistances of radiants are compared with Rk the busbar with the underestimated insulation resistance is determined by the results of comparison. Delivery of commands, inquiry of the measured voltages, evaluation and formation of effects of the control are carried out by means of the program module.
EFFECT: determination of real values of insulation resistance of busbars of independent radiants having one general busbar.
