Temperature sensor of thermal monitoring system for use in power distribution systems

A thermal monitoring system for use in a power distribution system, the thermal monitoring system comprising:

• a controller for temperature monitoring;
• and
• a temperature sensor coupled to the controller, the temperature sensor including:
• a ceramic printed circuit board (PCB) having a first side and a second side,
• wherein the ceramic PCB including a temperature sensing element disposed on the second side of the ceramic PCB,
• a terminal having a first end and a second end,
• wherein the first end of the terminal is configured to be fixed directly in contact with a measured point of an electrical component of the power distribution system and the second end of the terminal is directly in touch with the first side of the ceramic PCB such that heat is conducted from the terminal, through the ceramic PCB and then to the temperature sensing element, and
• wherein the temperature sensing element is configured to generate an electrical signal in response to the heat sensed by the temperature sensor from the electrical component,
• a pair of lead wires, wherein the electrical signal generated by the temperature sensing element is sent through the pair of lead wires to the controller for monitoring a temperature, and
• an epoxy to seal a portion of the terminal, the ceramic PCB in its entirety and a portion of the pair of lead wires to ensure a desired physical strength and a desired dielectric strength.
