This guide covers suggested test requirements for power system protection scheme testing@ system application tests@ the scope and level of tests based on the application@ and benefits of the overall protective schemes testing. This guide encompasses overall system testing procedures (generators@ line@ line reactors@ transformer@ capacitors@ special protection schemes@ end-to-end testing@ distributed application within substation@ etc.) and data collection requirements@ as well as the test procedure definitions. This guide describes the methods@ extent@ and types of system tests for protection applications at various voltage levels. Control functions inherent to the protective systems are included. Importance of line testing@ indirect trip applications@ open/closed-loop tests@ and dynamic onlinear tests are also covered. Purpose This guide is intended for power system protection professionals. It includes a reference list of type tests for protective devices as well as overall protection scheme performance tests for various types of protection schemes. The guide describes the methods@ extent@ and types of protection scheme tests. Interlocking and control functions inherent to the protective schemes are included.
