-
DTTS Distribution & Traction Transformer Test System
Containerized integrated design, capable of independently conducting factory tests on single-phase and three-phase distribution transformers as well as traction transformers. Ideal for mobile inspection scenarios.
-
TLMS Transformer Loss Measuring System
A computer-controlled high-precision loss testing system that automatically measures load loss, no-load loss, impedance voltage, and other parameters.
-
MPTTS Mobile Power Transformer Test System
Vehicle-mounted integrated solution supporting on-site testing and diagnosis, with turnkey engineering services available.
II. High-Power Testing Category
- SEPS Energy Storage High-Power Test System
Single module power up to 300 MVA. Requires only 200 kW charging power to independently perform transformer short-circuit tests, current transformer dynamic and thermal stability tests, and circuit breaker breaking capacity tests. Fully isolated from the power grid during operation, causing no impact on the grid.
III. High-Voltage Test Power Supply Category
