200 kVA Transformer – Reliable Power for Industrial and Commercial Applications

Summary

A 200 kVA Transformer is an essential component in modern electrical infrastructure, ensuring efficient voltage regulation and reliable power distribution across various sectors. Whether used in industrial plants, commercial complexes, or institutional facilities, this transformer helps maintain a stable power supply, reduces electrical losses, and enhances overall operational safety. With growing energy demands, a high-performance 200 kVA transformer provides the balance between efficiency, durability, and cost-effectiveness—making it a preferred choice for medium-scale power systems.

Understanding the 200 kVA Transformer

A transformer is designed to step up or step down voltage levels based on specific application needs. In the case of a 200 kVA unit, its power rating indicates the amount of electrical load it can safely handle. This capacity makes it suitable for small to medium industrial units, schools, hospitals, residential societies, and office complexes. It helps distribute electrical energy efficiently from main power lines to the required voltage levels for operation.

A 200 kVA distribution transformer typically comes in both oil-cooled and dry-type models. Oil-cooled versions are preferred for outdoor installations where higher efficiency and cooling are needed, while dry-type transformers are ideal for indoor spaces with safety and minimal maintenance in mind.

Key Features and Benefits

It is designed to minimize energy losses and deliver optimal performance even under heavy loads. The transformer is made with high-grade copper or aluminium windings, ensuring consistent performance and a longer service life. Its advanced core construction helps reduce operational noise, making it ideal for commercial and institutional settings. Furthermore, it is equipped with protective relays and temperature sensors that provide overload protection, preventing overheating or potential damage. The compact design and accessible terminals make installation and maintenance simple, while the eco-friendly build supports energy efficiency and reduced carbon emissions.

Applications of a 200 kVA Transformer

The 200 kVA transformer is versatile and widely used across industries for various applications. In manufacturing plants, it efficiently powers industrial machinery, motors, and heavy equipment. In commercial complexes, it provides reliable electricity for offices, malls, and retail stores. Educational institutions and hospitals rely on it for uninterrupted power supply to ensure smooth operations. Residential societies use it to distribute electricity safely across multiple buildings, while renewable energy systems such as solar and wind farms benefit from its ability to stabilize voltage levels and manage power effectively.

Technical Specifications

While specifications can vary based on manufacturer and configuration, a typical 200 kVA transformer includes a rated power of 200 kVA with a primary voltage of 11 kV or 33 kV, which can be customized as per requirement. The secondary voltage is usually 433 V or 415 V. Cooling options include ONAN (Oil Natural Air Natural) for oil-cooled transformers or air-cooled variants for dry-type units. The transformer operates at a frequency of 50 Hz and can come with insulation classes such as A, F, or H, depending on thermal requirements. Most models use the Dyn11 vector group to ensure optimal phase displacement and performance consistency. These specifications ensure that the transformer operates effectively under diverse load and environmental conditions.

Maintenance and Efficiency Tips

To ensure long-term performance, regular inspection and maintenance are crucial. Checking oil levels, insulation resistance, and temperature variations helps identify issues early. Cleaning the core, inspecting bushings, and monitoring load performance are essential practices that prevent sudden breakdowns. Timely servicing not only increases the transformer’s efficiency but also reduces operational costs and downtime. A well-maintained 200 kVA transformer can last for decades while maintaining stable and efficient power delivery.
