Padmounted Transformers: An Efficient Solution for Modern Electrical Systems

1. Introduction to Padmounted Transformers

Padmounted transformers are essential electrical devices in power transmission and distribution systems, particularly in urban areas, industrial zones, and regions with high safety and aesthetic requirements. With a compact and modern design, padmounted transformers are installed on the ground within a sturdy metal enclosure, protecting the equipment from environmental factors and ensuring human safety.

2. Structure and Working Principle

Padmounted transformers consist of key components such as the core, windings, and cooling system. This structure allows the transformer to perform its function of converting high voltage to a lower voltage suitable for the electrical needs of the serviced area. Notably, padmounted transformers typically use insulating oil for cooling and insulation, enhancing the device’s efficiency and lifespan.

3. Advantages of Padmounted Transformers

• High Safety: Padmounted transformers are fully enclosed, minimizing electrical safety risks and preventing accidents due to contact with live parts.
• Aesthetic Appeal: With a compact design and underground installation capability, padmounted transformers do not interfere with the surrounding landscape, making them suitable for modern urban areas.
• High Reliability: Efficient insulation and cooling systems ensure the transformer operates stably and durably in all weather conditions.
• Ease of Installation and Maintenance: The convenient design facilitates easier installation and maintenance, saving costs and time for power utility managers.

4. Applications of Padmounted Transformers

Padmounted transformers are widely used in urban areas, industrial zones, and regions with high aesthetic requirements, such as resorts and upscale residential areas. Additionally, these devices are ideal for areas with limited space where installing traditional transformers can be challenging.

5. Considerations When Choosing Padmounted Transformers

When selecting a padmounted transformer, it is important to consider factors such as capacity, voltage, environmental conditions, and maintenance requirements. Choosing reputable manufacturers ensures the quality and durability of the equipment.

Meet standards according to quality management systems

•  Measurement of winding resistance
•  Measurement of voltage ratio and check of phase displacement
•  Measurement of short-circuit impedance and loss
•  Measurement of no-load loss and current
•  Dielectric routine tests
•  Tests on on-load tap-changers, where appropriate
•  Leak testing with pressure for liquid-immersed transformers(tightness test)
•  Tightness tests and pressure tests for tanks for gas-filled transformers
•  Check of the ratio and polarity of built-in current transformers
•  Check of core and frame insulation for liquid immersed transformers with core or frame insulation
