In this paper, we report about the test result for Working Group 1 (WG1), which was established to make a Japanese guideline for spacecraft charging design. We investigated threshold conditions of sustained arc inception. The TJ (Triple Junction) GaAs solar cells were tested. Laboratory tests were carried out with an external circuit simulating a spacecraft power system. Solar array coupon panels simulating the hot and return ends of a string circuit were tested under various combinations of string voltage and string current. We revealed that the threshold conditions of sustained arc formation were different in string voltage even if the string current are same.
