Description
Product Overview
single and three-phase pad-mounted transformers are powerful, dependable, and designed with the environment in mind. With the ability to function indoors and outdoors, these transformers offer enhanced reliability and protection against critical equipment failure. The lower operating costs and heat emissions of these transformers make them an ideal choice for a wide range of applications.

Benefits
Pad mount transformers are protected against tampering and the weather, so they can be safely placed where people are present. All enclosures are made from heavy gauge sheet steel and powder painted with a baked-on coating to make them tamper-resistant. Our pad mount transformers come in live-front and dead-front designs, along with radial or loop feed. Our transformers are made of premium materials and typically support residential, commercial, and industrial loads in cities and rural areas. They are filled with sustainable and biodegradable dielectric fluid, which offers excellent fire protection and a longer lifespan. This transformer provides owners with substantial energy savings and offers environmental benefits. Higher efficiency extends the transformer’s lifespan and turns into significant cost savings in the form of lower energy bills and reduced ownership costs. This 50 KVA transformer from meets current efficiency standards for the United States and Canada. This transformer provides owners with substantial energy savings and offers environmental benefits.

Transformer Features
This 50 KVA pad-mounted transformer comes in single and three-phase configurations with a voltage rating of 2,400 – 46,000 V on the primary side and 208Y/120 V to 14,400 V on the secondary side. This unit’s cores are made from cold-rolled silicon steel laminations using state-of-the-art technology. This transformer is highly energy efficient with lower heat emissions, resulting in fewer cooling requirements. The unit also features mineral oil as an insulating fluid with a 65°C temperature rise. With its NEMA Type 3R enclosure, this pad-mount unit can be used for indoor or outdoor applications. This transformer is primarily used in Electric power distribution, stepping down primary voltage, energy management systems, and underground industrial power distribution.
FAQs
Our recommendation is that you buy a purpose-built step-up transformer instead of reverse feeding when possible.

The DGA has long been the most reliable and accurate method for determining the internal health of oil-filled transformers. The analysis requires drawing an oil sample from the unit, extracting the gasses from the sample, and analyzing the gasses through gas chromatography. The results of the chromatography tell the lab about different problems that may be arising inside the transformer. Some modern transformers have gauges on them that read levels of dissolved gasses in the oil in real time. But usually, the oil must be drawn and sent to a lab.
If you are unsure if an autotransformer is compatible with a particular piece of equipment, we recommend contacting the equipment manufacturer. However, as a general rule, this issue goes beyond the scope of an equipment manufacturers’ specifications since it is largely dependent on the existing electrical system configuration, where the equipment is installed, and local code requirements.
One hard and fast rule around autotransformer use: If the machine requires a neutral, and your system does not have one, an isolation transformer is required to create that neutral. Autotransformers do not create their own neutrals.
If your primary concern is lead time, repair is almost always quicker than buying a new unit—and this is especially true given the current supply chain crisis.
However, replacing the damaged unit with a reconditioned one can sometimes be just as fast or faster than repairing or replacing with a brand new unit. If an available reconditioned unit matches the dimensions of the unit in need of repair, you can sell the failing one and replace it with the reconditioned one.
Maddox has thousands of reconditioned, ready-to-ship transformers in stock for most common voltage configurations. These are typically available with a warranty comparable or identical to the warranties of newly manufactured units.
