Transformer Installation
We handle transformer installations of all sizes, ensuring reliable power distribution throughout your facility.
Chapter 01
When the voltage on the wall is not the voltage the machine wants
A lathe, a welder, a pump motor or an ag fan may be built for a voltage the building does not supply. Connect it anyway and it runs hot, runs slow, or does not run at all. Industrial and commercial operations often require transformer installations to manage voltage requirements, and a shop in East Texas finds this out the day the new equipment arrives.
Justin Zimmerman starts with the nameplate on the equipment and the voltage at your service. He measures what is actually there, not what the drawing says, because three-phase and single-phase, delta and wye, and the utility side all behave differently. Getting this right is the difference between a clean start-up and a burnt winding.

Sizing, mounting, protection on both sides, and the ground
We handle transformer installations of all sizes, ensuring reliable power distribution throughout your facility. Sizing is the first step: the connected load, the starting current of motors, and some headroom. A unit that is too small sags under load and overheats. One that is too large wastes money and space. Justin works the numbers before anything is ordered.
Mounting and protection come next. The unit is set where it can breathe, with working clearance in front of it and protection upstream on the primary and downstream on the secondary, each sized to the conductors and to the transformer itself. Grounding and bonding are done carefully, because the secondary is its own system that has to be tied to earth correctly.
Chapter 03
Inspection, labeling, and leaving it safe to service
When the transformer is energized, the work is only partly done. Justin checks the secondary voltage with a meter, under no load and then under load, and compares both to the nameplate. Then he labels the disconnects, the voltage, and what each breaker feeds, so whoever services it next, at midnight or in five years, knows exactly what they are looking at.
A transformer should hum quietly and stay warm, not hot. If you hear it buzz louder than before, smell hot varnish, or see a breaker trip on the primary, call (903) 218-3632. Installations around Brownsboro, Van and Athens carry the five-year labor warranty, and Justin would rather look at a unit early than watch the rest of your equipment pay for it.
