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 Analyser help to detect faulty transformer windings as well as defective tap positions.


Features:

  • Dissipation Factor (tanδ) and Power Factor (cosΦ )
  • Short Circuit Impedance and Excitation Current
  • Additional measuring capabilities like Capacitance, Quality Factor, Frequency, Voltage, Current, Power, Losses, Impedance, Inductance, Reactance, Spectrum Analyzer, Digital Scope and Data Logger
  • Frequency Response Analysis (optional; built-in or external remote controlled unit)
  • Turns ratio, voltage ratio, phase displacement (optional; built-in or external remote controlled unit)
  • Trending Analysis function – get a first graphical on-site assessment
  • Manual and Automatic (Sequencer) test operation.
  • Built-in high voltage supply up to 15kV, 4kVA
  • Built-in, long-term stable standard capacitor
  • Rugged, reliable and safe construction
  • State-of-the-art integrated PC running actual Windows platform with advanced user interface
