Datasheet
Designed for testing at local power-line frequency (50Hz or 60Hz), MIDAS automatically measures and records dissipation factor (tanδ), power factor (cosΦ) and all other relevant values of impedances (capacitive, inductive and resistive). Damage or changes in the insulation material are detected rapidly and reliably. Furthermore the optional build-in 3 phase Transformer Turns Ratio Meter and/or Frequency Response Analyzer help to detect faulty transformer windings as well as defective tap positions.
 
Benefits:
  • Shortest Measuring Time
  • Easy to operate
  • Highest Accuracy
  • Advanced interference suppression
