Electric power system phase detection systems and methods. One or more line mounted intelligent electronic devices (IEDs) measure voltage at various points of a power system. The measured voltage is timestamped with a reference signal and compared with a timestamped voltage at a location where a phase on each conductor of the power system is known. Pattern matching using the measured voltage may be used to determine the phase at locations where the phase is unknown.

A database stored electrical signatures of mounting points for generic modules within a vehicle model. Software for programming each mounting point is mapped to the mounting points. For a production unit of the vehicle model, generic modules are placed at the mounting points without being programmed to perform a specific function. The generic modules measure the electrical signature of the mounting point at which they are mounted. The generic modules then coordinate with a server to identify a matching electrical signature in the database and programming the generic modules with corresponding software for performing specific functions.
