The problems occurring in the relay protection vector testing for no -load and light-load lines during the startup of new power transmission equipment are discussed , the comprehensive solutions are analyzed , the points needing attention in the process of vector testing with load for new equipment startup are proposed , and a new testing method is put forward on this ba-sis.The new method not only improves the shortcomings that the protection vector cannot be tested in most no -load and light-load lines, but also significantly reduces the testing time , which ensures the safe and stable operation of power grid .
