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 of reactive power compensation devices, aiming at the problems existing in on-site measurement of individual capacitor capacitance in shunt capacitor banks at substations. It mainly solves the following problems:



(1) On-site measurement of individual capacitors requires disconnecting connecting wires, which is not only heavy workload but also easy to damage capacitors;



(2) The low output voltage of capacitance meter leads to low fault detection rate.



(3) Measuring the inductance of reactors. This instrument has the advantages of 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 CVT, lightning arrester, etc., with the function of one machine with multiple uses.
