Transformer losses and regulation

Copper and total losses, loading and voltage regulation.

Electrical engineering

Transformer copper loss

P꜀ᵤ = I₁²R₁ + I₂²R₂→Electrical engineering

Transformer total loss

Pₗ = P꜀ᵤ + P𝒇ₑ→Electrical engineering

Transformer voltage regulation

ΔU = (U₀ − U) / U × 100%→Electrical engineering

Transformer load factor

k = S / Sₙ × 100%→
