M201

Precision High Voltage Capacitance Bridge

Precision High Voltage Capacitance Bridge M201 measures the capacitance and dissipation factor (tanδ) with high accuracy

Measuring using M201 requires the use of the external high voltage standard capacitor

Maximum test voltage is limited higest voltage value of standard capacitor

FEATURES AND BENEFITS

  • High measurement accuracy C&tanδ testing: up to ± 0,002 % (Cx) and ± 0,00002 (tanδ)
  • Measurement of C&tanδ at test current up to 50 A
  • Easy handling
  • Small size and low weight

APPLICATIONS

M201 is used for:

  • Precision C&tanδ measurement of standard capacitors
  • Precision C&tanδ measurement of capacitors and HV cables with large capacitance
  • C&tanδ testing on rated voltage of: Instrument Transformers, Power Transformers, Bushings, Switches, Surge Arresters, Capacitors, Cables
  • Metrological research
