Abstract
Systems for testing a protective arrangement for an electric power delivery system without disconnecting merging units from a protective device are disclosed herein. For example, an intelligent electronic device (IED) may receive, via a monitoring port, one or more operating measurements of an electrical characteristic of the power delivery system while in an operating mode. The IED may change from operating in the operating mode to operating in a test mode. In the test mode, the IED may receive, via a test port, one or more test measurements that represent measurements of the electrical characteristic. The IED may provide test results based at least in part on the one or more test measurements.
