Technical Measures for Preventing Capacitor Device Accidents stipulates: For high-voltage shunt capacitor sections, the capacitance of each capacitor in the capacitor bank should be measured regularly. It is recommended to use a measurement method that does not require disconnecting the connecting wires, to avoid leakage faults caused by stress on the bushing due to disassembly and assembly of connecting wires.

Specifically developed to address 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 capacitors or the entire bank in 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 generators 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 displays voltage and current waveforms and phase, and calculates the power loss of the capacitor under test.

Working Principle


Edit

The fully automatic capacitance and inductance tester uses standard capacitors and synchronous sampling technology for the capacitor under test, which 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, good repeatability, accuracy, and reliability.
