With the expansion of global power, photovoltaic and telecommunication infrastructure, grounding performance is critical for facility safety. The 3-Point Ground Resistance Tester, adopting classic fall-of-potential principle, has been exported to the Middle East, Southeast Asia, Africa and other regions, widely used for acceptance and periodic inspection of substations, base stations and solar power plants.
Field sites usually feature uneven soil with stones and variable moisture. When operating the 3-Point Ground Resistance Tester, technicians shall drive two auxiliary ground stakes and naturally bury them two to three times at different spots. By comparing measured values from varied burying positions, operators can reduce errors caused by inhomogeneous soil and obtain credible test data. Built-in anti-interference filter circuit, 0.00Ω-2000Ω auto-ranging and real-time auxiliary-electrode resistance check help users identify bad stake-soil contact efficiently.
Equipped with backlit LCD screen for sunlight-readable display, dust-and-splash-proof housing and rechargeable lithium-ion battery, the unit fits long-time outdoor survey. Full package includes ground stakes, color-coded test leads, charger and hard carry case, together with English manuals and export calibration documents. The 3-Point Ground Resistance Tester delivers high-accuracy measurement for single independent grounding electrodes and complies with IEC field-test standards. It has been widely deployed in overseas new-energy and power-grid projects and gains positive comments from engineering contractors and third-party testing institutes.
