Transformer Tester / Inductance Tester Parameters Automatic Capacitance Bridge / Inductance Tester Parameters
Product Application:
It is specially developed under the guidance of the expert working group for reactive power compensation devices, aiming at the problems existing in on-site measurement of the capacitance of individual capacitors in shunt capacitor banks at substations. It mainly solves the following problems:
(1) On-site measurement of individual capacitors requires disconnecting connecting wires, which not only involves heavy workload but also easily damages the capacitors;
(2) The low output voltage of capacitance meters leads to a low fault detection rate.
(3) Measuring the inductance of reactors. This instrument features small measurement workload, quick 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 CVTs and arresters, providing multi-functionality in one instrument.
