Power line communication monitor
View Patent ↗A method of deployment of a power monitor system includes: coupling a monitor device that has a measurement component to a power line communication device for communicating a physical quantity measured by the measurement component across a power line; inserting a connection tap of an electrical access device into the power line through an insulation sheath to a conductor within the power line; attaching the electrical access device to the power line; and coupling electrically the electrical access device to the monitor device and the power line communication device.
1. A power monitor system, comprising:
a power line communication modem to communicate messages across a power line, wherein the power line communication modem communicates in accordance with a power line communication (PLC) protocol;
a monitor device having a measurement component coupled to the power line communication modem, wherein the monitor device is configured to monitor an electrical property as measured by the measurement component across the power line, and communicate, via the power line communication modem over the power line, the measured electrical property to an external computing device;
an electrical access device coupled to the power line, the electrical access device including a connection tap inserted into the power line to an electrical conductor within the power line, wherein the connection tap is electrically coupled to the power line communication modem and the measurement component; and
wherein the monitor device includes a processor configured by executable instructions to process one or more commands received by the power line communication modem and from the external computing device as a response to communicating the electrical property to the external computing device, wherein the processor is configured to execute the commands by controlling a facility device at or substantially proximate to an electrical load of the power line and said controlling includes enabling or disabling the facility device.
2. The power monitor system of claim 1 , further comprising:
an electronic switch operated by the monitor device to switch on or off power supplied to the electrical load of the power line; and
wherein the processor is configured to flip the electronic switch when a user command message is received at the power line communication modem after the measured electrical property is reported to a monitor terminal via the power line communication modem.
3. The power monitor system of claim 1 ,
wherein the connection tap has an extension inserted into an electrical interconnect through a second insulation sheath to a second conductor of the electrical interconnect; and
wherein the electrical interconnect is connected to the power line communication modem.
4. The power monitor system of claim 1 , wherein the measurement component is an electric current reader connected to a current transformer coupled to the power line separate from the electrical access device.
5. The power monitor system of claim 1 , further comprising:
an actuator coupled to a load of the power line;
wherein the processor is configured to activate the actuator when a command message is received at the power line communication modem.
6. The power monitor system of claim 1 , wherein the power line communication modem is attached to the measurement component.
7. The power monitor system of claim 1 , wherein the power line communication modem is attached to the electrical access device.
8. The power monitor system of claim 1 , further comprising an interference protector around the electrical access device.
9. The power monitor system of claim 1 , wherein the monitor device is coupled to an external measurement component located proximate to a load of the power line.
10. The power monitor system of claim 1 , further comprising a fan speed adjustment device coupled to the monitor device attached to a cooling fan proximate to a load of the power line.
