FIELD: measuring technology.
SUBSTANCE: method includes measuring temperature fields of electric equipment, reduction of measured temperatures Tmaxk(ti) to common conditions for measurements of electric modes of operation of electric equipment and parameters of environment with consideration of heat transfer coefficient of heat-emitting element in the moment of measurement, extrapolation of dependence Tmax(t1i) by time t, and determining remaining resource on basis of whether condition Tmax(t1i)≥Tcrit is satisfied.
EFFECT: increased trustworthiness of results of estimation of electric equipment condition.
