3 phase precision power analyzer is used for transformer loss measurement and motor testing. Model DXL780 is having 0.1% basic accuracy.


Three Phase Power Analyzer DXL780 is suitable for transformer & motor testing. It has 8 range of voltage & 8 range of current which is Auto or manually selectable. User interface by 22key become more easy and understandable. And the most efficient programming technique used to implement  FIR & IIR filter that gives steady result and option of selectable display update rate.

Three phase power analyzer DXL780 has harmonics measurement inbuilt. So user can check the harmonics of voltage or current upto 31th element. And also displays Total harmonics distortion THD value on the screen.

Three phase power analyzer DXL 780 is inbuilt memory to save the test results and later user can transfer it to excel by using software

Three phase power analyzer DXL780 is used for transformer testing, motor testing or any other electrical appliance testing. It is trusted by more than 3000+ customers all over the world. And we have state of the art manufacturing facility including inhouse fabrication and calibration lab.
