FIELD: electrical mechanics, in particular, use of information processing means in electrical mechanics, possible use for determining parameters of longitudinal links of equivalent circuit of one-phased transformers.
SUBSTANCE: arrays are registered for momentary values of input current |i1(tj)|, input voltage |uin(tj)|, output current |i2(tj)|, output voltage |uo(tj)|, voltage on third winding |u3(tj)| for same time moments tj=t1,t2,...,tN, where N=T/Δt - number of divisions within period T and Δt - discontinuousness of arrays of momentary values. Then, arrays of momentary values of output voltage are formed |u'o(tj)|, output current |i'2(tj)|, voltage on third winding |u'3(tj)|, taken for primary network. Arrays of momentary values of voltage are found on first |u'1(tj)| and second |u'2(tj)| longitudinal resistances of equivalent circuit, as voltage differences |uin(tj)| and |u'3(tj)|, |u'3(tj)| and |u'o(tj)|. Differentiation is performed of input and output currents to produce arrays 
and 
. Time moments are recorded, when i1(tj)=0(time moment t1), 
(time moment t2), i'2(tj)=0(time moment t3), 
(time moment t4). Then values of longitudinal active resistances are determined as well as those of inductivenesses of transformer equivalent circuit in accordance to formulae 
Average values of aforementioned parameters during period are calculated, which are taken as final result.
EFFECT: possible determining of parameters of longitudinal links of equivalent circuit of one-phased transformer in working mode.
