Import 3 Phase Capacitance And Inductance Tester — Buy in wholesale FOB from Supplier in China

The Wuhan GDMK Electric 3 Phase Capacitance and Inductance Tester is a field diagnostic instrument designed to measure capacitor capacitance and reactor inductance without requiring cable disassembly, addressing a known pain point in substation and industrial maintenance. The unit operates from a 220 V, 50 Hz mains supply with a rated output of 2V to 20V at 500 VA, sufficient to energise test objects while maintaining measurement stability. Its bridge-circuit architecture employs synchronous sampling against an internal standard capacitor, theoretically eliminating power supply voltage fluctuation errors and reducing the manual operation mistakes associated with traditional bridge methods.

The instrument measures 370 x 260 x 220 mm and weighs 15 kg, placing it in the portable category for site-based work rather than laboratory bench use. A Chinese-character LCD display and panel-mounted high-speed printer provide local result readout and hard copy generation, though the protocol for data export to external systems is not specified in the source. The automatic measurement process includes object identification and short-circuit protection, with the bridge structure comparing current through the standard capacitor and the tested capacitor to derive capacitance value via processor-controlled signal acquisition.

Target buyers include power utility maintenance departments, industrial plant electrical engineers, and electrical testing service contractors who perform periodic capacitor bank and reactor diagnostics. Applications span substation capacitor unit testing, power factor correction system maintenance, and reactor inductance verification in filter circuits. The source indicates operating ambient limits of -10°C to 50°C and relative humidity up to 90 percent, though calibration certification, measurement accuracy specifications, and traceability to national standards are not provided and must be requested from Wuhan GDMK Electric directly before purchase commitment.

Wuhan GDMK Electric Co., Ltd. is located in Jiangxia District Economic Development Zone, Daqiao New District, Huangjiahu Avenue, Wuhan, Hubei Province, China. The supplier holds harbor trust tier status, though like the first listing it shows a zero percent response rate and zero average response hours on platform channels, indicating no recent messaging activity through the host system. The company name suggests specialisation in electrical measurement and high-voltage equipment, with 'GDMK' likely an abbreviation or brand marker, though its meaning is not explained in available data.

No establishment year, employee count, factory size, R&D credentials, ISO certification, or client reference list is present in the source profile. The product description is technically detailed regarding operating principle but omits calibration traceability, warranty terms, after-sales service network, and whether the Chinese-character interface supports English language switching, critical for non-Chinese operators. Buyers should treat this as an unverified supplier profile requiring direct due diligence, factory visit, or third-party audit before significant financial commitment, particularly given the technical specialisation of capacitance and inductance measurement equipment.
