Abstract

Described is a transformer end-of-life thermal transmitting indicator (thermal transmitting indicator) that is configured and well suited for monitoring the health of a transformer and communicating the health of the transformer to an end user by way of a cellular transceiver. The thermal transmitting indicator can be configured to alert nearby people of an impending transformer explosion if the transformer fails. The thermal transmitting indicator is also arranged to transmit any problems or impending danger from the transformer to the end user who can then respond by preemptively dealing with the failing transformer.

Claims (30)

1. A transformer end-of-life thermal transmitting indicator comprising:

a housing essentially comprised of a cover and a base, the cover and base connected together to form an interior space;

in the interior space is a power supply adapted to provide electrical power to a cellular transmitter and a temperature sensor, the temperature sensor is external to the interior space;

an antenna connected to the cellular transmitter adapted to link to a cellular network, the thermal transmitting indicator configured to obtain a plurality of temperature values from the temperature sensor to transmit a digital representation of one of the temperature values, via the cellular transmitter, to an end user linked to the cellular network, the thermal transmitting indicator is configured to intermittently transmit the digital representation of the temperature values at a predefined time interval; and

an on/off button connected to the housing, when in an on state the thermal transmitting indicator is configured to intermittently transmit a first subset of the temperature values at a shortened time interval that is less than the predefined time interval, when in an off state the thermal transmitting indicator is configured to intermittently transmit a second subset of the temperature values at the predefined time interval.

2. The transformer end-of-life thermal transmitting indicator of claim 1 wherein the on state lasts between 0.5 hours and 2 hours before changing to an off state associated with the temperature values intermittently being transmitted at the predefined time interval.

3. The transformer end-of-life thermal transmitting indicator of claim 1 further comprising a light indicator configured to indicate when the on/off button is in the on state.

4. The transformer end-of-life thermal transmitting indicator of claim 1 wherein the temperature sensor is adapted to read temperature values from a transformer and the transformer end-of-life thermal transmitting indicator is configured to specifically work with the transformer.

5. The transformer end-of-life thermal transmitting indicator of claim 1 further comprising an audible alarm.

6. The transformer end-of-life thermal transmitting indicator of claim 1 further comprising non-transient memory configured to retain a history of the temperature values.

7. A method comprising:

providing a transformer end-of-life thermal transmitting indicator that possesses a housing essentially comprised of a cover and base that form an interior space, an antenna extending from the housing, a temperature sensor that is externally connected to the housing, the interior space including a power supply, a cellular transmitter connected to a controller and a computer processor;

attaching the temperature sensor an electrical device;

the thermal transmitting indicator receiving a first temperature value from the temperature sensor while the temperature sensor is attached to the electrical device;

transmitting the first temperature value to a consumer of data via a cell tower from the cellular transmitter;

after transmitting the first temperature value, receiving a second temperature value from the temperature sensor while the temperature sensor is attached to the electrical device;

transmitting the second temperature value from the cellular transmitter to the consumer of data via the cell tower at a predefined time interval that is defined between the first temperature transmission and the second temperature transmission;

after transmitting the second temperature value, receiving a third temperature value from the temperature sensor while the temperature sensor is attached to the electrical device; and

transmitting the third temperature value from the cellular transmitter to the consumer of data via the cell tower at the predefined standard time interval.

8. The method of claim 7 further comprising providing an on/off switch externally located on the housing; toggling the on/off switch to an on state.

9. The method of claim 8 wherein the on/off switch further possesses a light that indicates when the on/off switch is in the on state.

10. The method of claim 8 further comprising after the toggling step and while in the on state, receiving a fourth temperature value from the temperature sensor while the temperature sensor is attached to the electrical device;

transmitting the fourth temperature value from the cellular transmitter to the consumer data via the cellular tower;

after transmitting the fourth temperature value, receiving a fifth temperature value from the temperature sensor while the temperature sensor is attached to the electrical device;

transmitting the fifth temperature value from the cellular transmitter to the consumer of data via the cell tower at a shortened time interval that is defined between the fourth temperature transmission and the fifth temperature transmission, the shortened time interval is less than the predefined time interval.

11. The method of claim 10 wherein the thermal transmitting indicator continues transmitting ensuing temperature values from the temperature sensor to the consumer of data via the cell tower at the shortened time interval for a defined period of time after the toggling step.

12. The method of claim 7 further comprising triggering an audible alarm adapted to warn people of danger when one of the temperatures exceeds a preset limit.

13. The method of claim 7 further comprising transmitting a history of the temperature values to the cell tower, the history of the temperature values retained in non-transient memory in the interior space.

14. The method of claim 7 wherein the transmitting steps are accomplished automatically from the thermal transmitting indicator.

15. The method of claim 7 wherein the temperature sensor is adapted to read temperature values from a transformer and the transformer end-of-life thermal transmitting indicator is tailored to specifically work with the transformer.
