TSR – AC Resonant Test System

HAEFELY HIPOTRONICS’ tank type series resonant test systems are designed for testing power cables, power factor correction caps, generators and more. Allowing for multiple taps the TSR systems can provide voltage and current for many applications.



  • Patented reactor drive mechanism
  • Pure AC sine wave at output
  • Mobile via forklift or crane
  • PD free (down to 2pC, with necessary measures
  • 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
  • Low input power requires
  • Series or Parallel mode Applications


  • Cables
  • Generators
  • Power Factor Correction Capacitors
  • Bushings
  • CTs, PTs and CCVTs
  • Partial Discharge Testing
  • C & tan delta measuring
