The DC System Earth Fault Detector from Wuhan GDMK Electric Co., Ltd. is a portable instrument designed to locate ground faults in ungrounded or high-resistance grounded DC systems, typically found in power plants and substations. It operates using low-frequency signal injection and advanced signal processing algorithms to identify the exact branch and direction of insulation degradation. The device includes a high-precision current clamp for non-intrusive detection without interrupting system operation.
The detector uses fuzzy control theory to quantify the degree of insulation failure across multiple branches, displaying results numerically rather than through simple indicators. It is rated for DC systems from 24V to 480V and can function under live conditions without affecting connected control or protection circuits. The device is built for industrial environments, with an IP54-rated housing and operation within temperatures of -10°C to 50°C. The included clamp has a jaw opening of 40 mm to fit standard DC cable bundles.
This equipment is used by electrical maintenance teams in nuclear, hydroelectric, and industrial facilities where uninterrupted DC supply is critical for relay protection systems. Buyers include utility companies, EPC contractors, and automation system integrators. The device is shipped in a rugged carry case with calibration certificate, test leads, and user manual. Trade terms are typically FOB Wuhan Port, with lead times of 25 to 35 days. MOQ is not stated and must be confirmed directly with the supplier.

Before ordering, verify the device’s voltage rating matches your DC system, and request a copy of the calibration certificate with traceability to international standards. Confirm the operating temperature range suits your facility’s conditions, especially if used outdoors or in unconditioned spaces. Request a user manual in English and ensure the interface language is configurable if needed for your team.
Confirm the Incoterms, as FOB Wuhan is typical but not guaranteed. Ask for lead time in writing, as the listing does not specify it, and clarify payment terms (T/T or L/C). Request a detailed packing list showing components: device, clamp, battery, charger, test leads, and manual. Ensure the product is packed in a shock-resistant case for international shipping.
Conduct a pre-shipment inspection to verify the device powers on, the clamp reads zero under no-load conditions, and the display shows stable readings. Request a functional test report from the supplier under simulated fault conditions. Ensure the calibration certificate is dated within 12 months of shipment. For critical applications, arrange for third-party inspection before customs clearance.
