Delta Star power transformers are individually designed and manufactured to exceed the highest industry standards and the exact specifications for the particular application.
Delta Star specializes in engineering and manufacturing of high quality transformers up to 315 kV, 300MVA in both single and three phase configurations up to 1175 BIL. Utility applications include power, distribution, generator step up, unit auxiliaries (UAT), grounding units, voltage regulators and auto transformers.
|Type||MVA (Top Rating)||HV kV|
|Generator Step-up||Same Ratings as Type 1 & 2|
|Skid Mounted Substations||100||15-230|
Delta Star’s engineers use reliable, accurate and state-of-the-art special transformer design software (TDS). TDS includes optimization package (TRDO) for all types of designs, 3D magnetic field analysis (ELMAG 3D) for calculation of the losses and temperature rise of metallic components, 2D electrostatic field analysis (2D TELAX) for optimization of windings insulation structure and WELDINST for short circuit analysis (forces and stresses) including Dynamic Mode for axial forces and displacement of each section of the windings.
