The automatic capacitance and inductance tester features low measurement workload, quick and simple operation, stable performance, accurate measurement, and high fault detection rate; it can also measure the inductance of reactors, discharge resistance measurement function, measure the current and capacitance of coupling capacitors under live conditions, calculate the capacity of the measured capacitance; synchronously display voltage and current waveforms and phase; automatic range conversion, data storage; large-screen LCD display, Chinese output, and printing capability.
Due to the adoption of synchronous sampling technology for standard capacitors and capacitors under test, it is not affected by power supply voltage fluctuations; moreover, the measurement process is fully automatic
, avoiding errors caused by manual operation, thus featuring good stability, repeatability, accuracy, and reliability.
Main Functions
“Technical Measures for Preventing Capacitor Device Accidents” stipulates: For high-voltage shunt capacitor sections, the capacitance of individual capacitors in capacitor banks should be measured regularly, and it is recommended to use measurement methods that do not disconnect connecting wires to avoid faults such as oil leakage from bushings caused by stress during wire disconnection and reconnection.
It is specially developed to address the problems existing in measuring the capacitance value of individual capacitors in shunt capacitor banks and SCV devices at substation sites. It has the following functions:
* Measure the capacitance of individual or entire bank of shunt and integrated capacitors without disconnecting wires.
* Measure the inductance of reactors and line traps without disconnecting wires.
* Measure the entrance capacitance of transformers and generator entrance capacitance, etc., without disconnecting wires.
* Has the function of measuring parallel (discharge) resistance values.
* Can compensate for the problem of low fault detection rate caused by low output voltage of capacitance meters.
* Synchronously display voltage and current waveforms and phase, and calculate the power loss of the capacitor under test.
