Auxiliary transformers are a type of transformer that is used in electrical power systems to provide low voltage power for control circuits and other auxiliary equipment. They are essential components of power distribution and transmission systems, responsible for the safe and reliable operation of the system. Auxiliary transformers are typically located near the equipment they serve and are designed to provide a reliable source of low voltage power. They are available in a wide range of sizes and capacities, depending on the application. The design and construction of auxiliary transformers are critical to ensuring the safe and reliable operation of the electrical power system. Auxiliary transformers must be designed to withstand high levels of electrical stress and to operate under a wide range of operating conditions. The core and coil assembly of an auxiliary transformer is designed to minimize energy loss and reduce heat generation. The coils are wound to precise specifications to ensure efficient energy transfer, while the core is carefully designed to minimize hysteresis and eddy current losses. Auxiliary transformers are designed to meet a range of industry standards and regulations, including the National Electrical Code (NEC) and the International Electrotechnical Commission (IEC) standards. They are also subjected to rigorous testing and inspection to ensure that they meet the required performance and safety standards. Overall, auxiliary transformers are critical components of the power distribution and transmission system, responsible for providing reliable low voltage power for control circuits and other auxiliary equipment. Their design and construction are essential to ensuring optimal performance and long-term reliability.

Earthing transformers are designed to protect a system against phase-earth fault currents for a given fault time duration. These transformers are used to get a neutral point and provide earthing for non grounding systems. For example, when delta windings between two transformers are connected, the system is not earthed. In such a system earthing transformer provides grounding and protection against earth faults. These transformers are commonly "inter-star" or even known as Zig-Zag connected transformers. We have the expertise in manufacturing a wide range of earthing transformers based on customer requirements.

The Unit Auxiliary Transformer is the Power Transformer that provides power to the auxiliary equipment of a power generating station during its normal operation. This transformer is connected directly to the generator out-put by a tap-off of the isolated phase bus duct and thus becomes cheapest source of power to the generating station. It is generally a three-winding transformer i.e. one primary and two separate secondary windings. Primary winding of UAT is equal to the main generator voltage rating. The secondary windings can have same or different voltages i.e. generally 11KV and or 6.9KV as per plant layout.

Auxiliary Transformers are ideally designed to be used in railway industry to fulfill the power requirements of the auxiliary equipment. This transformer type is also regarded as economical source of the power. In the constriction of the transformer, there are three windings provided that includes one primary winding and two separate secondary windings. Moreover, the primary winding voltage rating is same as a main generator. The other two windings may be of the same or different voltages may it be 11KV and or 6.9KV, according to the application area.Our wide range of Auxiliary Transformers is specially designed keeping in mind the requirement of different industries.
