Import Digital Detector Partial Discharge Test — Buy in wholesale FOB from Supplier in China

The Digital Detector Partial Discharge Test from Wuhan GDMK Electric Co., Ltd. is a portable analyser designed to locate and characterise partial discharge activity inside power transformers. It provides four independent measurement channels together with a separate external trigger input, allowing simultaneous monitoring of multiple signals. The device samples at 200MSa/s with a 12‑bit analogue‑to‑digital converter, giving sufficient resolution to capture fast discharge transients. Its 6.5‑inch touchscreen hosts two USB ports, an Ethernet port and a VGA output for flexible data handling.

The instrument employs advanced signal‑processing algorithms and offers a synchronous frequency range of 30Hz - 1MHz, covering the typical spectrum of transformer partial discharge phenomena. Measurement parameters include discharge magnitude (Q), phase and density (N), and the system records amplitude‑time, magnitude‑phase and discharge‑count relationships every second. Power can be supplied from an internal lithium battery or from an external 220V 50Hz AC source, a configuration common to field‑portable test equipment. Designed for more than ten years of operation, the unit follows standard environmental tolerances of -10°C to 50°C for industrial electronics.

Typical buyers are utility companies, transformer manufacturers and maintenance contractors who need on‑site diagnostics to assess insulation health. The analyser is shipped as a complete system including the sensor, software and battery pack, and can be ordered under standard FOB terms from the Wuhan port. Prospective importers should confirm the exact MOQ, lead time and accepted payment method directly with the supplier before finalising the contract.

Wuhan GDMK Electric Co., Ltd. is located in the Jiangxia District Economic Development Zone of Wuhan, China, postal code 430200. The company holds a harbour‑level trust tier on the platform, although its reported response rate is currently zero and no average response time is recorded. Its registered address places it within a recognised industrial park that hosts several electrical equipment manufacturers. The listing for the Digital Detector Partial Discharge Test confirms that the firm offers this analyser as part of its product portfolio.

The supplier states that the detector is equipped with lithium‑battery operation and optional AC power, but it does not disclose certifications such as CE or IEC, nor does it specify minimum order quantities or production capacity. Prospective buyers should request a current factory audit report and a copy of the device’s calibration certificate to verify compliance with relevant safety standards. Communication with the company is required to obtain detailed trade terms and after‑sales support arrangements.
