Introducing the Small Power Transformer Test Set (SPTTS) series by Haefely, the ultimate solution for routine testing of power transformers. Designed to conform to international standards including IEC 60076 and IEEE/ANSI C57.12.90, the SPTTS system is equipped with advanced features to ensure optimal performance and accuracy.

At the heart of the system is a frequency converter-based power supply that utilizes our special control algorithm and a noise filtering circuit, making it ideal for transformer testing. With the SPTTS system, load loss measurements, no-load loss measurements, induced voltage tests, and temperature rise tests can be performed with ease and precision.

The modular design of the frequency converters allows for scalability in terms of power, ensuring that the system can adapt to the changing needs of your testing requirements. The Electronic Power Supply (EPS), frequency converter cabinet, EMC filter cabinet, and Logic Control cabinet are built into robust skids, providing durability and portability.

For even greater flexibility, the EPS can be built in containers, enabling testing in remote locations and harsh environments. With the SPTTS system, you can trust that your power transformer testing needs will be met with accuracy, reliability, and ease of use.
