产品描述
执行标准：IEC 61730-2 Ed.2“接地连续性试验”
BR-PV-GCT Ground Continuity Test System
Implementation of standards: IEC 61730-2:2004 & Ed.2, UL 1703-2008
Test Purpose:
To demonstrate that there is a conductive path between all exposed conductive surfaces of the module, so that the exposed conductive surfaces can be adequately grounded in a PV system. This test is required only if the module has exposed conductive parts such as a metal frame or a metallic junction box.
| Procedure: 1. Select the manufacturer's designated grounding point and recommended grounding connection. Attach to one terminal of the constant current supply. 2. Select an adjacent (connected) exposed conductive component with the greatest physical displacement from the grounding point, and attach to the other terminal of the current supply. 3. Attach the voltmeter to the two conductive components attached to the current supply in proximity to the current leads. 4. Apply a current 2.5 times ± 10% of the maximum over-current protection rating of the module for a minimum of 2 min. 5. Measure the applied current and the resultant voltage drop. 6. Reduce the current to zero. Five times test in different connection position. Pass criteria: The resistance between the selected exposed conductive component and each other conductive component of the module shall be less than 0.1Ω . |
