Under the guidance of the expert working group of reactive power compensation device, the automatic capacitance bridge tester ED2008B is specially developed to solve the problems existing in the field measurement of capacitor capacitance in substation. It focuses on solving the following problems:
◆ It is necessary to remove the connecting wire for on-site measurement of capacitor, which is not only a heavy workload but also easy to damage the capacitor;
◆ Low output voltage of capacitance meter leads to low fault detection rate. The instrument has the characteristics of small measurement workload, rapidity and simplicity, stable performance, accurate measurement and high fault detection rate.
◆ Its current measuring unit can also be used to measure CVT, lightning arrester and other electrical equipment, which has the effect of one machine with multiple functions.
