Welcome to the JCL Energy Blog

Transformers are not a catalog purchase. The right unit depends on your voltage class, your lead time, your site constraints and what you can actually get your hands on this quarter — and most of what's written about them online is written by people who have never had to load one on a flatbed.

This blog is our attempt at the opposite: practical write-ups from the people who spec, recondition, test and deliver this equipment every week.

What you'll find here

• Field notes — what we actually see on real substation, padmount and dry-type jobs, including the failures
• Buying guidance — lead times, voltage classes, kVA sizing and the spec gotchas that cost people months
• Repair vs. replace — when a unit is worth saving and when it isn't
• Maintenance — the checklists and testing that keep units in service

Where to start

If you're sizing a unit, start with how to choose the right kVA rating. If you're comparing suppliers, read where to buy electrical transformers. If you're weighing new against reconditioned, we made the case for reconditioned.
