A universal smart energy transformer module (USETM) that uses an array of sensors to monitor and measure characteristics of the electrical power delivered and utilized at a location, along with other conditions in the area surrounding the location. The invention then uses the data from these sensors to determine the condition and performance of the transformer (for example, its input and output, power quality etc.) and also to identify any anomalies detected within the local power system that could threaten reliable electric supply on the electric grid, or pose a danger to people. A notification of such condition may be distributed using the secure, uninterruptible communications system.

A method detects an error in a meter having a current transformer, a burden resistor unit and a resistive path switchably connectable across the burden resistor unit. The method includes obtaining in the processing circuit a first value representative of the voltage magnitude across the burden resistor unit while the resistive path is operably decoupled across the burden resistor unit. The method also includes closing a switching element to operably couple the resistive path across the burden resistor unit, and obtaining in a processing circuit a second value representative of a voltage magnitude across the burden resistor unit. The method further includes determining in the processing circuit whether an error exists based on the first value, the second value, and at least one predetermined stored value.
