345kV Power Transformer Overview

345kV Power Transformer is configured for 345kV grid transformation supported by 250MVA/345kV KEMA-tested project records.

For 345kV Power Transformer, the approved single-line diagram and data sheet convert 345kV grid transformation supported by 250MVA/345kV KEMA-tested project records into defined ratings, interfaces, component scope, tests, dimensions, and delivery records.

The 345kV page is built around 250MVA, 345/34.5kV KEMA-tested project records, with the offered rating, ratio, insulation level, impedance, cooling, accessories, and test matrix checked against the order scope.

A new 345kV project is reviewed by power, voltage ratio, winding arrangement, insulation levels, impedance, cooling, accessories, and specified test matrix before the data sheet is released.

Project acceptance combines the approved data sheet with order-specific routine, type, special, witnessed, or third-party tests, while earlier KEMA files and new-unit records stay clearly organized in the dossier.

Transport and field planning cover the actual ordered outline, shipping mass, removable assemblies, oil condition, route and crane limits, field assembly, oil processing, protection checks, and energization sequence.
