Auxiliary transformers (Single-phase and 3-phase)

Introduction

Auxiliary transformers are indispensable components in modern power systems, especially in critical installations like substations, industrial plants, and renewable energy facilities. Unlike main transformers used for power transmission, auxiliary transformers supply power to secondary systems, including control circuits, protection devices, and lighting. For Binary Engineering and Services, a leading manufacturer of low-voltage transformers below 415V (three-phase) and 230V (single-phase), these transformers represent a perfect blend of reliability and efficiency. Designed with outputs up to 750KVA, Binary Engineering and Services’ auxiliary transformers cater to diverse applications, ensuring operational excellence.

Working Principle

Auxiliary transformers operate on the principle of electromagnetic induction, stepping down voltage from a higher input level to a lower output suitable for auxiliary equipment. Binary Engineering and Services’ auxiliary transformers handle customer-specific custom input voltages and transform them to 415V (three-phase) or 230V (single-phase) to power control circuits and other auxiliary systems.

Three-Phase Auxiliary Transformers

These are used where balanced power across three phases is essential, such as in large industrial facilities. They ensure stable and efficient voltage transformation for systems with higher power requirements.

Single-Phase Auxiliary Transformers

Ideal for smaller setups, single-phase auxiliary transformers are compact and efficient for applications needing lower power, such as lighting or isolated control systems.

Both types enhance safety by providing electrical isolation between high-voltage systems and auxiliary systems, reducing the risk of faults or failures.

Design Considerations

The design of auxiliary transformers requires careful attention to ensure optimal performance and safety across applications. Key factors include rated power, which determines the transformer's capacity to handle auxiliary loads, and voltage ratings, ensuring compatibility with system requirements. The choice of winding configuration, such as star (Y) or delta (Δ), is critical for achieving the desired operational efficiency. Additionally, cooling methods, whether dry-type or oil-filled, must align with the installation environment and safety standards. Incorporating robust protection features like fuses and circuit breakers enhances reliability and safeguards against electrical faults, ensuring the uninterrupted operation of auxiliary systems.
