The Megger BM11D and BM21 5 kV Insulation Resistance Testers are portable, battery-powered
The Megger BM11D and BM21 5 kV Insulation Resistance Testers are portable, battery-powered, high-voltage instruments that use the latest electronic design and technology. The instruments have user-friendly keypads with push-buttons to select test voltages of 500, 1000, 2500, and 5000 V dc. In addition to the standard test voltages, a variable voltage feature on the BM21 selects test voltages between 25 and 5000 V dc in 25-V steps.
 
Features
  • Analog/digital display
  • Multiple test voltages
  • Integral timer
  • Automatic discharge of equipment under test
  • Comprehensive battery state indicator
 
Applications
  • High-voltage power cables
  • Large motor/generator windings
  • Line and substation transformers
  • High-voltage buses
