A power distribution transformer is used to step down medium voltage (for example, 11-33 kV) to low voltage levels suitable for end users, such as 400/230 V in many systems. It is installed on poles, pads or inside kiosks near load centers. Distribution transformers are designed for high efficiency at light to medium loads since they are energized continuously and often lightly loaded. They typically have fixed or limited tap ranges, simple protection and focus on robustness, low no load losses and minimal maintenance in everyday service.

Utility designs reflect grid code requirements, contingency loading, maintenance philosophy, remote monitoring, and interoperability with protection and SCADA systems.

International-spec power transformers are used wherever equipment or projects span multiple grid standards: global EPC projects, export-oriented manufacturing, offshore platforms, shipping, cross-border interconnectors, and multinational industrial groups. These transformers are designed to comply with IEC/IEEE and various regional codes, enabling deployment in Africa, Middle East, Asia, Europe, and the Americas without major redesign, thus serving diverse industrial and utility customers worldwide.

Hammond Power Solutions transformers are often used in heavy duty industrial sectors such as metal processing, mining, automotive manufacturing, chemical plants and large HVAC systems. They also serve data centers, oil and gas, renewable projects and commercial buildings that need robust dry type or liquid filled units. Their control and isolation transformers are common in motor control centers and automation panels. Customers value rugged construction, multiple voltage options and compliance with North American safety standards.

There is no single fixed drying time for a 5 MVA transformer in a vacuum oven, because it depends strongly on initial moisture content, insulation thickness, and the applied temperature and vacuum level. In practice, for a mid-size 5 MVA unit, a typical drying cycle ranges from 48 to 120 hours. Well-prepared transformers with moderate moisture may be dried in 2-3 days, while heavily wetted insulation can require 5 days or more. The end point is defined by moisture evolution rate and insulation resistance, not by time alone.

132/33 kV transformers are used to step down transmission voltages for distribution feeders supplying cities, industrial clusters, and commercial loads.
