Field issues are rare, and when they happen it seems like they come out of nowhere. You look into the matter and find out the problem was with something as simple as a mounting bolt. We at Hill Tech have been examining these issues and providing solutions to keep assemblies and configurations running smoothly without easily avoidable hiccups. Today, we’re examining commonly looked over installation issues with toroidal transformer set ups.<\/p>\n\n\n

Types of Toroidal Transformer Failures<\/h2>\n\n\n\n

We recently had a situation that involved toroidal transformer failures, and at first it seemed as if the malfunction was happening at random. When we looked closer, we found that the problem was linked to excessive torque being applied to the center bolt during its assembly.<\/p>\n\n\n\n

When using disc-style mounting hardware to install toroidal transformers, it is essential to apply the correct amount of torque. We\u2019ve seen issues arise whenever the installer unintentionally over-tightens the center bolt, especially in designs where the primary winding is made from a thinner gauge wire than the secondary one. With this added pressure, the internal windings can become too compressed. This leads to installation breakdown and, ultimately, a short in the primary.<\/p>\n\n\n\n

What makes this especially difficult is that these issues are hard to find. They can start and build up in ways that are easy to miss. The problems might only reveal themselves when the unit is in operation. And these invisible difficulties can create catastrophic problems: if the primary fuse isn\u2019t fast enough to blow, the insulation could completely melt down, creating a massive disaster.<\/p>\n\n\n\n

Let Us Help<\/h2>\n\n\n\n

We at Hill Tech want to avoid invisible issues that build up like this. That\u2019s why we aim to do more than just supply components- we want to inform about best practices, too.<\/p>\n\n\n\n

To prevent toroidal transformer failure, we provide them pre-marked with the recommended torque specifications. We can even label the mounting plate with a clearly visible \u201cDo Not Exceed\u201d torque rating. Simple preventative measures can make a massive long-term difference.<\/p>\n\n\n\n

If you\u2019re assembling toroidal transformers and want to make sure you\u2019re maintaining precision and care, let us help! We\u2019ll get you set up with the right components and supply options for your design and assembly process.<\/p>\n\n\n\n
