Product descriptions from the supplier
Description of Aux Transformer
An Auxiliary Transformer (Aux Transformer) is a specialized low-to-medium voltage transformer designed to supply reliable power to auxiliary systems in industrial facilities, power plants, substations, and large commercial complexes. Its core function is to step down high-voltage electricity (typically 10kV–35kV) from the main grid or generator to low-voltage levels (380V/220V) suitable for auxiliary equipment, such as pumps, fans, lighting, control systems, and communication devices. These auxiliary systems, though not directly involved in primary power generation or transmission, are critical for maintaining the overall operational efficiency, safety, and stability of the facility.
In normal condition the standing by transformer stays in hot condition, i.e. high voltage side is charged. Once any problem happens to the main transformer, the standing by transformer will be put in operation, which is for internal use only.

Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?In substations, equipment such as power and distribution transformers, transmission lines, voltage transformers, current transformers, and disconnect switches all require grounding. Beyond grounding, we will now explore in depth why gravel and crushed stone are commonly used in substations. Though they appear ordinary, these stones play a critical safety and functional role.In substation grounding design—especially when multiple gr01/29/2026 -
Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
