发布时间：2022-02-25

The capacitor–inductor tester employs a next-generation high-speed hybrid microprocessor, offering a highly integrated design. It simultaneously acquires the voltage and current signals of the device under test and automatically calculates parameters such as capacitance, inductance, and reactive power. On-site measurements of capacitors can be performed without disconnecting the connecting leads, simplifying the testing procedure, significantly improving operational efficiency, and preventing damage to electrical equipment. Upon completion of the test, the instrument automatically computes the capacitance of each phase and other relevant parameters, enabling easy identification of changes in capacitor quality and faults in inter‑component conductors. Additionally, the device features data storage and USB communication capabilities, eliminating the need for on-site data transcription and ensuring the integrity of measurement results.

The capacitor–inductor tester incorporates a three-phase AC test source and, without disconnecting the wiring, can directly measure the single‑phase capacitance of grouped parallel capacitors or the capacitance of three‑phase capacitors in various connection configurations. It can also measure the inductance of reactors. With simple wiring and convenient testing and data recording, it significantly enhances operational efficiency. Featuring a large‑screen color LCD display and menu‑driven operation with Chinese character prompts, it presents multiple parameters on a single screen. Its user‑friendly human–machine interface is intuitive and easy to use, making it a popular choice for power utilities at all levels.

The capacitor–inductor tester was specifically developed to address the challenges encountered when measuring the capacitance of individual capacitors within shunt capacitor banks at substation sites. It effectively resolves the following issues: on-site measurement of a single capacitor requires disconnecting its connecting leads, which is not only labor‑intensive but also risks damaging the capacitor; the low output voltage of conventional capacitance meters results in a low fault‑detection rate; and it can measure the inductance of reactors. This instrument features reduced workload, rapid and straightforward operation, stable performance, high measurement accuracy, and an elevated fault‑detection rate. Additionally, it can measure reactor inductance, includes a discharge‑resistor measurement function, enables live‑line measurement of coupling capacitor current and capacitance, calculates the measured capacitance value, displays voltage and current waveforms and phases simultaneously, offers automatic range switching, stores data, and provides a large LCD display with Chinese-language output and built-in printing capabilities.
