HAEFELY / Tettex

The TMS 600 represents a modern, precision-driven solution for transformer measurement and testing applications. Designed to support high-voltage environments, it delivers accurate, repeatable data critical for validating performance, efficiency, and compliance across a wide range of transformer types. Built with robust components and advanced measurement capabilities, the system ensures dependable operation in both laboratory and field conditions.

The TMS 600 performs automated measurements of:

Load loss

No-load loss

Heat run

Induced voltage test

Zero sequence impedance

Loss measurement on shunt reactors

Harmonic analysis

With its integrated wattmeter and Haefely’s advanced CaMS™ software, the TMS 600 enables streamlined measurement and data acquisition without additional calculations. All test data is readily accessible for export and integration into external analysis and reporting systems.
