Testing Transformers Should Be Efficient and Safe
Routine tests for distribution transformers are often time-consuming and require multiple manual steps. The TTS1000L Series reduces complexity through automated sequences, precise measurement technology, and a safe remote-operated workflow.
Sine Inverter Power Supply for Transformers up to 2000kVA
With the innovative and efficient frequency converter technique, a sinusoidal output voltage with low harmonic is generated.
The output frequency range is 50-400Hz, this allows AC induced voltage tests. The wide voltage and current range and the precise regulation are the ideal solution for routine testing of power transformers.

TTS1000L System Overview
The Distribution Transformer Test System Setup
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, operated with the Solfas Test Suite 2 software, is designed for maximum flexibility and fully automated test execution, minimizing manual intervention and significantly reducing overall test time.
Once the transformer is connected, the complete test sequence is safely and conveniently controlled from a remote control unit PC. This ensures reliable operation, high operator safety, and fast, comfortable testing. Predefined and customizable test plans allow fully automated execution of all standard and special transformer tests, while comprehensive reporting guarantees complete traceability and professional documentation of all results.
All Routine Tests in One System
The following tests are performed in accordance with IEC 60076:
One Transformer, One Test Report
Test reports are automatically generated after each test and stored on a central file server. Authorized users can access them directly for fast review and documentation.
This ensures consistent, professional test documentation for efficient quality assurance and reporting.
