Abstract

An electrical power system including an electrical power connector, a contact configured to electrically connect a power supply to a load, a first sensor configured to sense a first characteristic of the electrical power connector, a second sensor configured to sense a second characteristic of the electrical power connector, and an electronic controller. The electronic controller configured to receive the first and the second characteristics, analyze the first and second characteristics, and determine an abnormal condition based on the analysis.

First claim

The invention claimed is:

1. An electrical power system comprising:
an electrical power connector;
a contact transformer module including a contact and a contact core, wherein the contact is configured to electrically connect a power supply to a load, and the contact core is configured to receive the contact;
at least one toroidal transformer winding integrated into the contact core, the at least one toroidal transformer configured to sense a current of the electrical power connector;
at least one selected from a group consisting of a temperature sensor configured to sense a temperature of the electrical power connector and a voltage sensor configured to sense a voltage of the electrical power connector; and
an electronic controller configured to
receive a first signal indicative of the current and a second signal indicative of at least one selected from a group consisting of the temperature and the voltage,
compare the first and second signals to one or more thresholds, determine an abnormal condition based on the comparisons, and
dynamically adjust the one or more thresholds based on at least one selected from a group consisting of a measured or calculated parameter, an installation condition, an operational limit, a known operational behavior, and parameter threshold information.

2. The electronic power system of claim 1 , wherein the sensed temperature is a temperature of a core of the electrical power connector.

3. The electronic power system of claim 1 , wherein the threshold is a default value based on an application of the electrical power system.

4. The electronic power system of claim 1 , wherein the electronic controller is located within the electrical power connector.

5. The electronic power system of claim 1 , wherein the electronic controller is located on at least one selected from the group consisting of an external communication device, an external wiring device, a remote server, and a cloud network.

6. The electronic power system of claim 1 , wherein the controller is partially located within the electrical connector and partially located on at least one selected from a group consisting of an external communication device, an external wiring device, a remote server, and a cloud network.

7. The electronic power system of claim 1 , wherein at least one of the first signal and the second signal is based on an installation condition.

8. The electronic power system of claim 7 , wherein the installation condition is at least one selected from a group consisting of an expected/allowed temperature range, an indoor versus outdoor use, a degree of climate control or non-climate control, a level of moisture/humidity, a natural temperature variation, a geographical location, and an installation location.

9. The electrical power system of claim 1 , wherein the controller is further configured to provide a maintenance schedule tracker.

10. The electrical power system of claim 1 further comprising a load, wherein the controller is further configured to determine an abnormal condition of the power system based on information received from the load.

11. The electrical power system of claim 1 , wherein the controller is further configured to utilize machine learning and artificial intelligence algorithms to perform or improve prediction or diagnostic capability based on the information received from at least one selected from the load.

12. The electrical power system of claim 11 , wherein the controller is further configured to utilize machine learning and artificial intelligence algorithms to further improve prediction capability based on the information received from the load.

13. The electrical power system of claim 1 , wherein the abnormal condition is further based on one or more installation conditions and one or more parameter thresholds.

14. An electrical power system comprising:
an electrical power connector configured to receive AC power;
a contact carrier including one or more power terminals and a contact
transformer module, wherein the contact transformer module includes one or more connector contacts and one or more contact cores, each of the one or more contact cores configured to receive one of the one or more connector contacts;
a transformer winding integrated into each of the one or more connector contacts, the transformer winding configured to sense a current traveling through the respective connector contact; and
an electronic controller configured to compare the current to a threshold, wherein the electronic controller is further configured to dynamically adjust the threshold based on at least one selected from a group consisting of a measured or calculated parameter, an installation condition, an operational limit, a known operational behavior, and parameter threshold information.

15. The electrical power system of claim 14 , wherein the contact carrier further includes one or more contact transformer modules.

16. The electrical power system of claim 15 , wherein the transformer winding is integrated into the one or more contact transformer modules.

17. The electrical power system of claim 14 , wherein the transformer winding is one selected from the group consisting of a Ragowski helical coil and a biased winding toroid.
