According to the measurement requirements of leakage current from the national standards such as Standard GB9706.1-2007, this article describes the existing problems of isolated power earthing during leakage current measurement. Aiming at improving the measurement accuracy and protecting the security of testing engineers, we analyses several methods for isolated power earthing during the leakage current measurement, and various reasons of possible differences among test values of leakage current. Based on the existing national standards, this article proposes alternative testing methods for discussion.
