SDMyers Transformer Maintenance and Testing

Maximizing the effective, reliable life of your transformer equipment.

Since 1965, we have pioneered transformer management with the highest quality in service and products.  With our founder’s vision for life extension of the most critical asset in your electrical system – the transformer – we are committed to being an advocate for our customers. We hope you find the content of this site helps you connect your ever-growing needs with the right solution – our team.

To remain competitive in today’s economy, your organization needs RELIABLE, LOW COST and UNINTERRUPTED POWER. Due to aging equipment, increased load demands, and less time and money available for preventive maintenance, the risk of transformer failure will continue to increase. In addition, key personnel who understand this risk and who possess the knowledge and expertise to make a difference are a scarce commodity today. The need for planning and preventive asset management principles is more prominent than ever to reduce your company’s risk of lengthy downtime and significant revenue losses.
