MSR - AC Resonant Test System

Additional Product Information

Features & Benefits


  • Patented reactor drive mechanism
  • Oil temperature indicator(s)
  • Pure AC sine wave at output
  • Option for a mobile system via air pads
  • Low PD operation (e.g. < 2pc for cable test applications)
  • No transient over voltages generated during flashover
  • PC based controls hardened for industrial & laboratory applications (with remote assistance)


  • Provides a protective voltage collapse should the device under test fail
  • Multiple Q values to meet a variety of applications
  • Turnkey PD test solutions including engineering services
  • Negligible harmonic distortion
