Software

The programs HVCC writes for its own work.

A complete design system for large power transformers and a diagnostic database for transformer fleets. Both are used every day on real projects at HVCC, and both are supplied to customers together with the engineers who use them.

Lightning impulse calculation in Power Transformers Design: voltage and stress at every node of the series winding

Transformer design up to this class: 400 kV
Transformers in the example fleet: 137
Desktop, runs offline: Windows
Adaptation, validation, training: On site

The two programs

One designs the transformer. The other keeps it alive.

Design and diagnostics are the two ends of the same forty years of practice: the faults a diagnosis finds are the ones a design should have prevented.

Design software, version VS02

Power Transformers Design

Electrical, dielectric, short-circuit, thermal and mechanical design of oil-immersed power transformers, from nameplate to clamping drawings, with FEM and transient modules in one environment.

Nine design steps on one model: nameplate, regulation, core, windings, impedance and losses, short circuit, dielectric, thermal, mechanical
Short-circuit forces with buckling, tilting and the loads on the clamping structure
Lightning and switching impulse, induced voltage and partial-discharge stress node by node
Hot spot by IEC and by FEM, and the dimensioned drawings of the 23 clamping components

For regional manufacturers of 50 – 400 MVA units, factories being set up, and engineering, repair and review firms.

Diagnostic software

Oil Analysis & Maintenance

A diagnostic database for transformer fleets: dissolved-gas and oil-quality diagnosis of every unit by the methods of IEC 60599 and IEEE C57.104, with a verdict per transformer.

Owners, transformers and analyses in one database, with the whole history of each unit
Rogers, Doernenburg, key gas, Duval triangle, TDCG and furans, with the verdict in words
Oil condition gauges and a reconditioning or reclamation call
Included in HVCC condition-assessment contracts, or supplied with technology transfer

For utilities and generators, industrial plants and maintenance teams that own more transformers than diagnosticians.

Why HVCC writes its own software

Tools written by the people who sign the design.

Written on real projects

Every screen on these pages is a real design file or a real fleet database, not a demo. The rules inside come from transformers that were built, tested and, sometimes, opened after a failure.

Adapted, not sold as they are

Material catalogues, design rules, level limits and manufacturing constraints are set to the customer's own before delivery.

Delivered with the engineer

A validation project against test results, training on site and a maintenance agreement come with the licence. The program is the start of an engineering relationship, not the end of a sale.

Where they have been used
