Features and Advantages
1. The tester with adjustable power output, both single-phase and three-phase transformer, can be used to complete all windings of the measurement only need connect the wire once time, testing and wiring simply; inside of the instrument uses a phase-locked loop technology, synchronous sampling AC 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.
