Voltage regulation of a large transformer is mainly influenced

Home » Electrical Machines » Electrical machines miscellaneous » Question

Voltage regulation of a large transformer is mainly influenced by

1. no-load current and load power factor
2. winding resistances and load power factor
3. leakage fluxes and load power factor
4. winding resistances and core loss

Correct Option: B

% Regulation =	I(R_e₂cosθ ± X_e₂sinθ)
	V₂

cos θ is power factor
