Web17 de mai. de 2024 · Figure 1 – Ground grid integrity test using a high current DC source (GGT series) GGT is a powerful DC current source that provides DC test currents up to 300 A. High output voltage enables testing with long cables (e.g., 60 m) and measurement of a wide range of resistance values. WebThe earthing system, in combination with protective devices such as fuses and residual current devices, must ultimately ensure that a person does not come into contact with a metallic object whose potential relative to the person's potential exceeds a safe threshold, typically set at about 50 V.
