Abstract
A method for obtaining an improved transformer design for a power plant, including the steps of defining one or more critical temperatures (θ, θ, θ, θ) in the operation of the transformer, determining a limit (θ, θcontingency, θh, θ) for at least one of the critical temperatures and obtaining an adjusted design of the transformer by using a data set of transformer loading, the data set comprising the amount of time (H) at a specific load level (κ) for a specific ambient temperature (θ). The method further includes the step of producing a transformer having the adjusted values of the design parameters (Δθ, Δθ, R, x, y) and/or using a transformer having the adjusted values of the design parameters (Δθ, Δθ, R, x, y) in the power plant.
