据印度《动力和河谷开发》1977年10月号报道:彭奇水电站厂房建在地面以下约100米处,开关站则建于地面。根据工程的电网分析,最大的地面漏失电流约1万安培。这将发生显著的升压,会危及厂房附近工作人员的生命安全。因此,将电站加上接地格栅结构作为保护措施。 According to India’s “Power and River Development” October 1977 report: Peng Qi hydropower plant built about 100 meters below the ground, the switch station is built on the ground. According to the project’s grid analysis, the largest ground leakage current of about 10,000 amperes. This will result in a significant boost and will endanger the lives of staff near the plant. Therefore, the power grid plus grounding grid structure as a protective measure.
