Portable DC Ground Fault Locator

This cost-effective DC ground fault locator, model A0E10003, features easy and convenient operation, high resolution signal sampling and direct current clamp meter. It performs fault testing for indirect grounding, non-metal grounding, loop grounding, positive and negative grounding, positive and negative balance grounding, and multipoint grounding in DC systems efficiently. It displays system voltage, voltage to ground, and grounding resistance. This high-performance ground fault locator also detects sensitive ground leakage and indicates direction of ground point. In addition, an insulation alarm threshold value can be set by users.

This portable DC ground fault locator belongs to GAO’s family of Earth Ground Testers. The line includes two similar products: Double Clamp Earth Resistance Tester and Single Clamp Earth Tester. They are widely used to test soil resistivity and leakage current of grounding systems under different conditions. The line also includes Handheld Earth Ground Tester which conducts 2-pole, 3-pole and 4-pole earth resistance tests and also measures AC voltage and soil resistivity. This line of earth ground testers is widely used in detecting reliable ground connections and measuring earth ground resistance.
