Efficient Transformer Testing with Full Automation and Precision
The TTS1000L series delivers a flexible and scalable transformer test platform for routine and advanced testing of low voltage power transformers and power chokes. Fully automated operation, precise measurement technology, and comprehensive reporting enable reliable test execution with minimal manual intervention and full result traceability.
Sine Inverter Power Supply for Transformers up to 2MVA
The innovative and efficient frequency converter technique generates a sinusoidal output voltage with low harmonic distortion.
The output frequency range of 50-400 Hz allows for AC-induced voltage testing. The wide voltage and current range, as well as the precise regulation, make this the ideal solution for routine power transformer testing.
Key Benefits
TTS1000L System Overview
Safety First
The system features an EN 50191–compliant, modular safety solution that provides reliable protection for operating personnel against hazardous voltages while flexibly adapting to individual test setups and workplace conditions.
A broad range of accessories enables optimal configuration of the system to meet specific application, layout, and safety requirements.

Comfortable Operation and Reporting
The TTS1000L series, powered by Solfas Test Suite 2 software, provides a highly automated and flexible test environment that minimizes operator interaction and optimizes overall test efficiency.
All tests are performed remotely via a dedicated control unit PC after the transformer is connected, enabling safe, fast, and comfortable operation. Standardized and user-defined test plans support fully automated test sequences, while detailed, professionally formatted reports ensure complete documentation and traceability of all measurement results.

All Routine Tests in One System
The following tests are performed in accordance with IEC 60076:
Automated Test Report Generation
Test reports are automatically generated after each test and stored on a file server for long-term traceability. They can be accessed directly from any authorized workstation, allowing fast review, analysis, and documentation.
Each report provides a complete and transparent record of the test sequence, including all measured values and evaluation results. This ensures consistent, professional test documentation for efficient quality assurance and reporting.
