a)Uch cho’lg’amli transformatorlarda reaktiv quvvatning keltigan isroflarinni aniqlaymiz.

I – variant:

II – variant:

b)Transformatorni salt ishlash vaqtidagi keltirilgan isrofni aniqlaymiz.

I – variant:

II – variant:

c)Ttransformatorning qisqa tutashuv revimidagikeltirilgan isrofni aniqlash.

I – variant:















=45+203,4*288.77.



=2*45+0,5 (203,4*211.88.

II – variant:

=75+265,5*194.09.



=2*75+0,5(265,5*209.54.

d)Uch cho’lg’amli transformator yoki avtotransformatordagi elektr energiya isrofini aniqlaymiz.

I – variant:



=2*45*8760+0,5*(*203,46*1816+*171*1816+*

146,93*1816)=1009801

II – variant:



=2*75*8760+0,5*(*265,5*1816+*179,5*1816+*149,5*1816)=1422141

bunda, -вн; сн; нн cho’lg’amlaridagi maksimal isroflar vaqti bo’lib, xissoblar uchun teng deb qabul qilinadi.
