  • Product Features
    1. This transformer tester has adjustable power output, single-phase and three-phase transformers. It can be used to complete all winding measurements. It only needs to connect the wires once, and the test and wiring are simple. The instrument uses phase-locked loop technology to synchronize sampling and communication. Signal, measurement data is accurate.
    2. Test and algorithm is to meet the<< DL/T1093-2008 power transformer winding deformation detection and judgment >>, and automatically calculate the short-circuit impedance, reactance and inductance value of each phase.
    3. Test data can be imported into the computer to facilitate further analysis or storage; support external power supply, expand the test power.
    4. Through the anti large screen liquid crystal, in the sun can be clearly displayed; all Chinese menu and operation tips, simple and intuitive operation.
