Systems, methods, and devices are provided for controlling part of an electric power distribution system using an intelligent electronic device that may rely on communication from wireless electrical measurement devices. Wireless electrical measurement devices associated with different phases of power on an electric power distribution system may send wireless messages containing electrical measurements for respective phases to an intelligent electronic device. When wireless communication with one of the wireless electrical measurement devices becomes inconsistent or lost, the intelligent electronic device may synthesize the electrical measurements of the missing phase using electrical measurements of remaining phases. The intelligent electronic device may use the synthesized electrical measurements to control part of the electric power distribution system.

A test instrument can be coupled to a test point and measure signals in the network. The test instrument may determine whether the test instrument is connected to a cable of the network and provide notification if the test instrument is not connected to a cable. The test instrument may also detect when it is connected to a customer premises that has been previously been tested through reflected signal signatures.
