Electrical cabinet infrared monitor
First Claim
1. A monitoring system for a cabinet, the system comprising:
- an infrared camera configured to capture thermal images of at least a portion of monitored electrical equipment positioned in an interior cavity of the cabinet;
a communication interface configured to transmit the thermal images from the infrared camera for external viewing by a user;
an electromagnetic coupler configured to be disposed adjacent to at least one conductor of the monitored electrical equipment within the cabinet and receive a magnetic field generated concentrically to a current passed by the at least one conductor of the monitored electrical equipment within the cabinet;
an energy harvesting circuit coupled to the electromagnetic coupler and configured to provide electrical power in response to a change induced in the electromagnetic coupler by the magnetic field; and
a battery configured to store the electrical power and to power the infrared camera.

Abstract
Various techniques are provided to monitor electrical equipment. In some implementations, a monitoring system for a cabinet may include an infrared camera configured to capture thermal images of at least a portion of electrical equipment positioned in an interior cavity of the cabinet. In some implementations, the monitoring system also includes a communication interface configured to transmit the thermal images from the infrared camera for external viewing by a user. In some implementations, the thermal images may be provided through various wired and wireless communication techniques. In some implementations, the infrared camera may receive electrical power through a physical coupling to an electrical connector within the cabinet and/or through electromagnetic energy harvesting techniques. Other implementations are also provided.

20. A method of monitoring an interior cavity of a cabinet, the method comprising:
-
capturing, by an infrared camera, thermal images of at least a portion of monitored electrical equipment positioned in the interior cavity of the cabinet; transmitting, by a communication interface, the thermal images from the infrared camera for external viewing by a user; receiving, by an electromagnetic coupler disposed adjacent to at least one conductor of the monitored electrical equipment within the cabinet, a magnetic field generated concentrically to by a current passed by the at least one conductor of the monitored electrical equipment within the cabinet; providing, by an energy harvesting circuit coupled to the electromagnetic coupler, electrical power in response to a change induced in the electromagnetic coupler by the magnetic field; storing, by a battery, the electrical power; and powering, by the battery, the infrared camera. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
