Abstract

Example devices and methods for compensating for monitoring a surge protection device are provided. In some embodiments, a device is configured to couple to a surge protection device. The device comprises a processor that is capable of sending a DC current signal. A serial data interface is electrically connected to the processor and includes at least one shift register. The device also comprises a multiplexer coupled to the serial data interface. The serial data interface is operable to direct the DC current through the multiplexer. The device also comprises an analog to digital converter (optionally embedded within the processor) that is operable to output a digital signal corresponding to a voltage induced by the DC current signal. Returned DC signals represent surge protection device's health and a multitude of other surge module information.

First claim

What is claimed is:

1. A method comprising:
sending, from a monitoring device, a DC current signal to a surge protection device component of a surge protection device, wherein the DC current signal generates an induced voltage at the surge protection device component;
determining, by the monitoring device, a health of the surge protection device component based on the induced voltage; and
generating, by the monitoring device, an output capable of being displayed on a display device, wherein the output is based at least in part on the health of the surge protection device component.

2. The method of claim 1 , wherein the output provides an indication of a change in the health of the surge protection device component.

3. The method of claim 1 , further comprising determining, by the monitoring device, information relating to the surge protection device component, wherein the determined information comprises an identification of at least one of a surge protection device technology, mode setup, or calibration setting.

4. The method of claim 1 , further comprising determining, by the monitoring device, information relating to the surge protection device component, wherein the determined information comprises an identification of at least one of a surge protection device surge capacity or temperature.

5. The method of claim 1 , further comprising determining, by the monitoring device, information relating to the surge protection device component, wherein the determined information comprises an identification of a surge protection device component configuration.

6. The method of claim 5 , wherein the surge protection device component configuration comprises at least one of 7-mode protection or 10-mode protection.

7. The method of claim 1 , further comprising using, by the monitoring device, a database of a manufacturer of surge protection devices to determine information relating to the surge protection device component.

8. The method of claim 1 , wherein measuring the health of the surge protection device component comprises measuring a temperature of the surge protection device component.

9. The method of claim 1 , further comprising, selecting, by the monitoring device, a module of a plurality of modules that contains the surge protection device component.

10. A monitoring device comprising:
a processor; and
a memory including computer program code, which when executed by the processor, causes the monitoring device to:
send a DC current signal to a surge protection device component of a surge protection device, wherein the DC current signal generates an induced voltage at the surge protection device component;
determine a health of the surge protection device component based on the induced voltage; and
generate an output capable of being displayed on a display device, wherein the output is based at least in part on the health of the surge protection device component.

11. The monitoring device of claim 10 , wherein the output provides an indication of a change in the health of the surge protection device component.

12. The monitoring device of claim 10 , wherein the memory further includes computer program code, which when executed by the processor, causes the monitoring device to determine information relating to the surge protection device component, wherein the determined information comprises an identification of at least one of a surge protection device technology, mode setup, or calibration setting.

13. The monitoring device of claim 10 , wherein the memory further includes computer program code, which when executed by the processor, causes the monitoring device to determine information relating to the surge protection device component, wherein the determined information comprises an identification of at least one of a surge protection device surge capacity or temperature.

14. The monitoring device of claim 10 , wherein the memory further includes computer program code, which when executed by the processor, causes the monitoring device to determine information relating to the surge protection device component, wherein the determined information comprises an identification of a surge protection device component configuration.

15. The monitoring device of claim 14 , wherein the surge protection device component configuration comprises at least one of 7-mode protection or 10-mode protection.

16. The monitoring device of claim 10 , wherein the memory further includes computer program code, which when executed by the processor, causes the monitoring device to use a database of a manufacturer of surge protection devices to determine information relating to the surge protection device component.

17. The monitoring device of claim 10 , wherein measuring a health of the surge protection device component comprises measuring a temperature of the surge protection device component, and the surge protection device component comprises one of a varistor, a thermistor, a resistor, a capacitor, an inductor, a fuse or a sensor.

18. The monitoring device of claim 10 , wherein the memory further includes computer program code, which when executed by the processor, causes the monitoring device to select a module of a plurality of modules that contains the surge protection device component.

19. The monitoring device of claim 18 , wherein each of the plurality of modules resides on a different circuit board.

20. A computer program product comprising a non-transitory computer-readable medium having computer-readable instructions stored thereon, which when executed by a processor, causes a monitoring device to:
send a DC current signal to a surge protection device component of a surge protection device, wherein the DC current signal generates an induced voltage at the surge protection device component;
determine a health of the surge protection device component based on the induced voltage; and
generate an output capable of being displayed on a display device, wherein the output is based at least in part on the health of the surge protection device component.
