Weshine Electric Manufacturing Co., Ltd
Given the diverse functional requirements of the grid’s protection system, testing capabilities require a new level of sophisticated test hardware and software with which to analyse the entire protection system’s (or individual protection component’s) operation in "real life" situations. It is further necessary that these expanding testing capabilities be met with a similar improvement in the simplification of a test instrument’s user interface and software control.
