Quality and customer satisfaction are our focus: staring with order reviews, all engineering phases, supplier quality programs, inspections in all manufacturing steps, which includes incoming material, in-process and finished product; shipping and all the way to customer handshake after field installation.

Our quality assurance programs ensure product quality and reliability in all phases of engineering and manufacturing.  Because quality is of the utmost importance to us, we have created what we like to call, the “VA Way” Five Star Quality System:


  • Knowledgeable and dedicated leadership with “Quality first Mindset”
  • Critical to Quality (CTQs) control plans, design standards and shop operating procedures developed from over 45 years of experience
  • Training, audit and skill certification program which assures the product reliability and craftsmanship
  • Experienced Technical leaders embedded in all areas of manufacturing
  • Final assurance program which strives to achieve customer satisfaction at all stages of project execution from order receipt to transformer installation on the pad

Engineering Quality Assurance

  • Customer order reviews and design control plan for each order
  • Design validation plan with failure mode effect analysis (FMEA) for new designs, new components and new technology
  • Engineering Process Audit (EPA) and inspection plan for engineering process assurance

Vendor Quality Assurance

  • AQL quality control plan for incoming material inspection
  • New component evaluation and testing plan
  • New Vendor Evaluation and Vendor performance score card
  • Vendor quality surveillance audits and vendor rating system

Process Assurance in Manufacturing

  • Training and skill certification programs for operators
  • Statistical Process Controls (SPC) for critical processes of transformer manufacturing
  • Three tier quality control plan for process adherence to assure product quality

Final Quality Assurance
