Non-intrusive power quality sensor
View Patent ↗A non-intrusive power quality sensor for to provide a simple solution for monitoring the quality of the power behind the meter. 80% of the quality issues happen behind the meter. Current power quality monitoring solutions are intrusive: they require the intervention of an electrical qualified person. The non-intrusive power quality sensor generally includes a device that can be plugged into a regular power outlet and acts as a power quality sensor.
1. A non-intrusive power quality sensor device that is plugged into a regular power outlet and acts as a power quality sensor, the device comprising:
a power quality sensor;
a base unit;
the base unit is a logic device that hosts one or multiple sensors that are connected in a wired or wireless connection to it;
the base unit transforms the data so that it is processed by other systems, devices, or applications; and
the base unit monitors the sensor metrics and generate alerts using multiple digital or analog alerting capabilities;
a sensor cable;
the sensor cable connects the power quality sensor to the base unit; and
the sensor cable transmits data and power;
a display;
a power cable;
the power cable is plugged into the power quality sensor on one end and on the other end, the power cable is plugged into a power socket or outlet; and
wherein the power quality sensor is plugged into a power socket or outlet and acts as a non-intrusive power quality sensor.
2. The device of claim 1 , wherein
the power quality sensor is a device that analyzes the quality of the power in respect to the voltage quality and the total harmonics voltage distortion of the power coming from the connected power cable.
3. The device of claim 2 , wherein
the data is shown on a display on the device and/or made available using digital or analog communication protocols to other devices, applications or systems.
4. The device of claim 1 , wherein
the sensor is programmed to monitor other power elements.
5. The device of claim 4 , wherein
the sensor is programmed to monitor power failures.
6. The device of claim 1 , wherein
the base unit is a logical unit in a sensor platform that receives data from sensors, processes it and makes it available to other platforms.
7. The device of claim 6 , wherein
the base unit; manages alerts including: email, SNMP, SMS, and voice calls.
8. The device of claim 1 , wherein
the display shows the power quality as sensed and as performed per industry standards.
9. The device of claim 1 , wherein
the display enables a user to see the status of the quality of the power, the most recent power abnormalities that were found; and
the messages on the display are designed in such a way that they are easy to understand without requiring special electrical knowledge.
10. The device of claim 1 , wherein
the power cable is either modular or part of the device.
11. The device of claim 1 , wherein
the device is plugged directly into a power socket.
12. The device of claim 1 , wherein
the power cable is plugged into a wall socket or any other type of socket.
13. The device of claim 1 , wherein
the power cable is a regular power cable that either is embedded or simply connected to the device and the power socket.
14. The device of claim 1 , wherein
the power cable is either directly or indirectly connected to the device.
15. The device of claim 1 , wherein
the power cable is connected using a power connector.
16. The device of claim 1 , wherein
the power cable is connected to a wall socket.
17. The device of claim 1 , wherein
the power cable is connected to a power switching board to a power cable, either directly or indirectly.
18. The device of claim 1 , wherein
the power cable is connected to an AC power source or a DC power source, where it monitors the same and/or other power quality metrics relevant to the monitoring requirement.
19. The device of claim 1 , wherein
the functionality of the base unit is integrated into the power quality sensor to form a single unit; and
the power quality sensor with an integrated base unit is connected to one or more additional base units.
20. The device of claim 1 , wherein
the connection from the power quality sensor to the base unit is wired by using a cable or it is connected in a wireless configuration between the power quality sensor and the base unit or any combination thereof.
21. The device of claim 1 , wherein
the non-intrusive power quality sensor computes the power quality and monitors if it is within defined thresholds; and
those thresholds are based on either industry standards, user set metrics, or any combination thereof.
