1. A system for detecting a fault in a distribution transformer of a power transmission system, the system comprising:
a current sensor positioned to sense a primary output current flowing from the distribution transformer; and
a processor operable to:
receive an output of the current sensor over time;
generate a time-varying output signal representing the received output of the current sensor;
compare at least the time-varying output signal to one or more transformer fault profiles to produce a fault analysis; and
generate an alert when the fault analysis indicates a transformer fault condition.
