Transformer loss calculation method

Transformer loss calculation method Transformer loss power is divided into iron loss and copper loss, iron loss, also known as no-load loss, is its fixed loss, the real is the loss generated by the iron core (also known as iron core loss, and copper loss is also called load loss). One Transformer loss formula (1) active loss: ΔP = Po + KT β2 Pk (2) reactive power loss: ΔQ = Qo + KT β2 Qk (3) Comprehensive power loss: ΔPz = ΔP + KQΔQ Qo ≈ Io%Sn, Qk ≈ Uk%Sn Where: Qo – no-load reactive power loss (kvar) Po – no-load loss (kW) Pk – rated load loss (kW) Sn–Transformer rated capacity (kVA) Uk% – short-circuit voltage percentage β–Load factor, the ratio of load current

About Transformer silicon steel

Commonly used transformer core is generally made of silicon steel sheet. Silicon steel is a kind of silicon (silicon is also called silicon) steel, its silicon content in 0.8 ~ 4.8%. The core of the transformer is made of silicon steel because silicon steel itself is a kind of magnetic material with strong magnetic conductivity, and it can produce large magnetic induction intensity in the energized coil, which can reduce the size of the transformer.
