● When measuring a single capacitor on site, it is necessary to remove the connecting wire, 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.
● Measure the inductance of reactor.
The instrument has the characteristics of small measurement workload, rapidity and simplicity, stable performance, accurate measurement and high fault detection rate. In addition, 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.
The Technical Measures for Preventing Accidents of Capacitor Devices stipulates that the capacitance of a single capacitor of a capacitor bank should be measured regularly for the part of high-voltage parallel capacitors, and it is suggested that the measurement method should be adopted without disconnecting the connecting wires, so as to avoid the failure of casing oil leakage caused by the stress caused by disconnecting the connecting wires.
