Overview

Distribution transformers step down medium-voltage power to the lower voltages used by homes, businesses and local grids. They come as oil-filled or dry-type units, with features like on-load tap changers, conservators and cooling systems. Buyers look for capacity (kVA/MVA), voltage ratings, insulation condition and transportability when selecting used units for substations or commercial sites.

FAQ

What should I inspect when buying a used distribution transformer?

Check the nameplate ratings, kVA and voltage class, manufacturing date, oil condition or insulation status, tap changer condition, bushing integrity, maintenance and fault records, and results of recent electrical tests (insulation resistance, turns ratio, winding resistance, and DGA if oil-filled).

How do I ship a distribution transformer safely?

Use heavy-equipment carriers with proper lifting gear and blocking. For oil-filled units confirm local rules—some jurisdictions require draining or special containment. Secure and protect bushings and tap changers, use skid or frame supports, and arrange permits/escort for oversized loads.

What regular maintenance does a distribution transformer need?

Perform periodic visual inspections, oil testing (DGA, moisture, acidity) for oil-filled units, check and service tap changers, clean and tighten bushings and connections, monitor temperature and load, and repair leaks or corrosion promptly. Follow manufacturer intervals and keep detailed records.
