Technical measures to prevent accidents in capacitor devices stipulates: For high-voltage shunt capacitor sections, the capacitance of individual capacitors in the capacitor bank should be measured regularly, and it is recommended to use a measurement method that does not disconnect the connecting wires to avoid leakage faults caused by stress on the bushing due to disassembly and assembly of connecting wires.

It is specially developed for the problems existing in measuring the capacitance 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 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.

* Simultaneously display voltage and current waveforms and phase, and calculate the power loss of the tested capacitor.


Working Principle


Edit

The automatic capacitance and inductance tester adopts synchronous sampling technology for standard capacitors and tested capacitors, which is not affected by power supply voltage fluctuations; in addition, the measurement process is fully automatic, avoiding errors caused by manual operation, so it has the characteristics of good stability, good repeatability, accuracy and reliability.
