T&D Buyer's Guide

For nearly 50 years, SDT North America has helped the world’s most reliable companies achieve their operational objectives through better asset reliability. Our technology empowers maintenance and reliability teams to foresee failures, eliminate energy waste, and make smarter, safer decisions.

Ultrasound is often the first indicator of change in an asset’s condition. Its sensitivity to friction, impacting, and turbulence makes it one of the most versatile condition monitoring technologies available—capable of detecting subtle defects long before other methods.

At SDT, we harness this power across the 8 Pillars of Ultrasound:

• Bearing Condition Monitoring

• Precision Lubrication

• Compressed Air & Gas Leak Detection

• Steam Trap & Valve Testing

• Electrical System Inspection

• Hydraulic System Testing

• Tightness Testing

• Pump Cavitation Detection

Our portable ultrasound data collectors and acoustic imaging cameras are known for their accuracy, repeatability, and ease of use—trusted by industries across the globe to increase uptime, improve sustainability, and reduce operational risk.

Discover why SDT is known as The World’s Favorite Ultrasound Company—and how we help you bring reliability into focus.

Did you know 1 out of every 200 transformers experiences failure each year? The safety and cost risks of an unexpected failure can be catastrophic. Dynamic Ratings products and services provide real-time data to help you make smart asset management decisions. Online monitors give you the confidence to extend the life of existing assets using real-time data. Monitors evaluate the equipment in your substation (transformers, circuit breakers, switchgear, and more) and measure their performance to make sure everything is working properly. If something looks out of place, an alarm will notify you of the problem. This information allows utilities to optimize maintenance plans and the performance of their assets to changing system requirements. Learn how we can help at www.dynamicratings.com.
