Parameters of Automatic Capacitance Bridge / Inductance TesterParameters of Automatic Capacitance Bridge / Inductance Tester
Product Application:
It is specially developed under the guidance of the expert working group of reactive power compensation devices to address the problems existing in measuring the capacitance of individual capacitors in parallel capacitor banks at substations. It mainly solves the following problems:
(1) On-site measurement of individual capacitors requires removing connecting wires, which is not only heavy workload but also easy to damage capacitors;
(2) The low output voltage of capacitance meters leads to low fault detection rate.
(3) Measuring the inductance of reactors. This instrument has the advantages of small measurement workload, fast and simple operation, stable performance, accurate measurement, and high fault detection rate.
In addition, its current measurement unit can also be used for measuring electrical equipment such as CVT and arresters, providing multi-function capability.
