How to Read Transformer Specifications: kVA, Voltage, Insulation & More

Transformer specifications can seem confusing for non-professionals. Understanding key parameters is essential to choose the right model and avoid mismatches.

kVA represents the rated capacity and determines the maximum load the transformer can support. Voltage parameters include primary and secondary voltage, which must match your power grid.

Insulation class determines thermal stability and safe working temperature. Common classes include B, F, and H, with higher classes supporting higher temperatures.

Connection group label affects phase sequence and is essential for parallel operation. Vector group labels must be correct to avoid phase conflicts.

Protection level (IP code) indicates dustproof and waterproof performance. Higher IP ratings are required for outdoor, humid, or dusty environments.

By learning these basic parameters, buyers can quickly compare models, communicate with suppliers accurately, and make better purchasing decisions.
