FIELD: electricity.
SUBSTANCE: method is carried out by the electric signals substantially different from the known formation methods thereof, compared in the measuring device. The time function is used on the basis of the formation causing the measuring protection body failure, which is the operation line reflection of the measuring body in the period interval T=1/f, and herewith the instantaneous time function value is functionally associated with the integral AC voltage parameter on the electrical object, and short-time pulses , causing the measuring body actuation, have an amplitude, that is associated with the integral AC parameter in the electrical object input.
EFFECT: expansion of the measuring protection body functionality .
