Introduction  

DC resistance meter (YR-20W type) is important for measuring DC resistance of transformers. It is used for current transformers, power & distribution, and more. It is also practical for temperature rise test. This instrument is designed for transformers, whose resistances of LV windings and HV winding have a great difference.   

Features:

  • Interval time: 10s / 30s / 60s, during test of temperature rise.  
  • Double power and constant current.
  • Easy operation with color touch panel.  
  • Test LV winding / HV winding effectively.
  • Handle the test data with temperature rise software.
  • USB port to download test data and 485 communication port.
  • Protection for 380V AC power supply.  
  • Discharge alarming.
