Commercial & Industrial Transformer Services

Orth Electric transformer and panel work

Transformers step voltage up or down so a facility's electrical system can safely deliver the power its equipment needs, and when one fails or is undersized, it can take down an entire building or production line. Orth Electric installs, replaces, troubleshoots, and repairs transformers for commercial and industrial customers throughout Butler and Warren County and the surrounding area. That includes step-up and step-down transformers, general dry-type units common in commercial buildings, and pad-mount considerations for facilities with outdoor equipment. We also handle the load calculations and service upgrades that go hand in hand with a transformer change, so the new equipment is matched correctly to the building's actual demand rather than guessed at.

Load Calculations Come Before Equipment Choices

Transformer work sits at the point where utility-level power meets a building's internal distribution, and getting it wrong is not a small mistake. We calculate loads before recommending transformer capacity, verify that dry-type or pad-mount equipment is appropriate for the location and application, and coordinate any related service upgrade so the transformer, the panel, and the feeders all match. Our team works across the full voltage spectrum, from 480-volt three-phase industrial distribution down through standard commercial and residential voltages, which means one licensed crew can handle the transformer and everything downstream of it on the same project.

Frequently Asked Questions

How do I know if my facility's transformer is undersized?

Common signs include voltage that sags under load, breakers tripping when multiple pieces of equipment run at once, or a facility that has added equipment or expanded since the transformer was installed. We can evaluate your current load against the transformer's capacity and tell you whether an upgrade is actually needed.

What is the difference between a dry-type and pad-mount transformer?

Dry-type transformers are air-cooled and typically installed indoors or in an electrical room, common in commercial buildings. Pad-mount transformers sit outdoors on a concrete pad, often oil-cooled, and are typical for larger facilities or where a utility service enters the property outdoors. We can evaluate which fits your building.

Does replacing a transformer mean I also need a service upgrade?

Not always, but the two are often connected. If a facility is adding equipment or increasing its electrical demand, the transformer, the main panel, and the service feed may all need to be sized up together. We calculate the actual load first so you are not paying for more than the building needs.

How long does a transformer replacement take?

It depends on the size of the unit, whether it is dry-type or pad-mount, and whether utility coordination is required. We will give you a realistic timeline during the estimate and plan the work to minimize downtime for your operation.

Can you troubleshoot a transformer that is causing intermittent power problems?

Yes. Intermittent issues, humming, overheating, or unexplained voltage problems can often be traced back to a transformer or its connections. We test the unit and the surrounding circuits to find the actual source before recommending a repair or replacement.
