Abstract
Disclosed is a watt/watthour meter which is capable of automatically correcting incorrect connections between the apparatus and a multiphase AC system. Each power line of the multiphase system is connected to the watt/watthour meter by means of a voltage input line and a current sensing coil. The apparatus is able to determine whether a given voltage input line is connected to the same power line as a given current sensing coil by determining whether the voltage applied to the given voltage input line has the same phase as the current running through the given current sensing coil. If the current and the voltage are the same, this information is stored, and the given voltage input line may be taken as being connected to the same power line as the given current sensing coil.
