Load-side voltage sensing in a power meter

A metrology device comprising:

• a load-side voltage detection module, the load-side voltage detection module including:
• a plurality of first resistors electrically coupled to a first line-side terminal, the first resistors being in series;
• a plurality of second resistors electrically coupled to a second line-side terminal, the second resistors being in series;
• a voltage divider electrically coupled between a first line-side terminal and a second line-side terminal, the voltage divider creating a reference voltage for the load-side voltage detection module;
• and
• a pulse generator to generate a pulse based on detection of voltage, the pulse indicating a voltage on at least one of the first line-side terminal or the second line-side terminal, above at least one threshold.

A network, comprising:

• a metrology device communicatively coupled within the network;
• and
• a central office communicatively coupled to the metrology device at least in part over a power line,
• wherein the metrology device includes:
• a metrology unit, the metrology unit including a load-side voltage detection circuit, the load-side voltage detection circuit including:
• a plurality of first resistors electrically coupled to a first load-side terminal, the first resistors being in series;
• a plurality of second resistors electrically coupled to a second load-side terminal, the second resistors being in series;
• a voltage divider electrically coupled between a first line-side terminal and a second line-side terminal, the voltage divider creating a reference voltage for the load-side voltage detection module;
• and
• a pulse generator to generate a pulse based on detection of voltage, the pulse indicating a voltage on at least one of the first load-side terminal or the second load-side terminal, above at least one threshold.
