GUILDLINE – AC High Voltage Capacitance and Inductance Bridge

Guildline Instruments 9910A High Voltage Capacitance Bridge is a measurement standard employing the AC Current Comparator principle. The Current Comparator principle is applied to the measurement of ratio and dissipation factors of high voltage capacitors in a similar manner to the classical Schering Bridge but with greatly improved accuracy and resolution.

Categories: ,
  • Better than 15 ppm accuracy
  • Permanent Direct reading
  • Six-digit measurements
  • Capacitance Range:100 pf to 1000 μF
  • Dissipation factor up to 11.1 percent
  • Working Voltage to 50 kV with 9911
  • Safe to operate, even into megavolt region.
  • Bridge components remain at ground potential.
