1. A method of determining which phase of a three-phase power supply a load meter is connected to, the method comprising the steps of:

  • transmitting a timing pulse;

    receiving the timing pulse at the load meter;

    determining a time delay at the load meter from receipt of the timing pulse until a landmark value of a single phase voltage of the three-phase power supply feeding the load meter; and

    determining the phase of the three-phase power supply the load meter is connected to based upon the determined time delay.
