Power line communication and power distribution parameter measurement system and method

A system, device, and method of providing information for a power distribution system is provided. In one embodiment, a method of using a device that receives power from the low voltage power of the power distribution system and experiences a power loss during a local power outage may perform the processes of monitoring a voltage of the low voltage power line, detecting a voltage reduction below a threshold voltage for a predetermined time period, storing information of the voltage reduction in a non-volatile memory prior to the power outage, and transmitting a notification to a remote computer system prior to the outage. The monitoring may comprise making a plurality of measurements of the voltage during a time interval and averaging the plurality of voltage measurements. In addition, the method may include transmitting an alert message upon power up after the outage to indicate a power restoration local to the device.

The object of the invention is to provide a slotted current acquisition coil according to the Rogowski principle in which the printed circuit board base of the measuring coil can be opened to insert an electrical conductor to be measured without having to interrupt the latter. To this end, the two printed circuit board segments linked together by a hinge are opened. Twisting a single-piece printed circuit board also opens the arrangement for inserting the conductor to be measured.
