Abstract

An intelligent electronic device (IED) is provided. The IED includes a metering sub-assembly and an input base module sub-assembly. The metering sub-assembly is hinged to the input base module sub-assembly, where when in an open position, various cables, connectors, and input/output cards/modules are accessible. Various input/output cards/modules are interchangeable to add/change functionality and/or communication capabilities to the IED.

First claim

What is claimed is:

1. A filter board for use with an intelligent electronic device (IED), the filter board comprising:
at least one first contact configured to be coupled to at least one voltage input for receiving sensed voltage;
a current limiting section coupled to the at least one contact configured to limit current passing through the filter board;
a suppressor section coupled to the current limiting section, the suppressor section configured to suppress noise and prevent an over-voltage surge condition; and
at least one second contact coupled to the suppressor section and configured to output the received sensed voltage to at least one component of the IED.

2. The filter board of claim 1 , wherein the received sensed voltage is an alternative current (AC) voltage and the filter board further comprises a rectifier section coupled to the current limiting section, the rectifier section configured to convert the AC voltage to direct current (DC) voltage.

3. The filter board of claim 2 , further comprising a buffer coupled to the rectifier section and configured to receive the DC voltage from the rectifier section and store energy to be provided to the at least one component of the IED via the at least one second contact.

4. The filter board of claim 2 , further comprising a common mode filter coupled between the rectifier section and buffer, the common mode filter configured to prevent electromagnetic interference and radio frequency interference.

5. The filter board of claim 4 , wherein the common mode filter is an inductor.

6. The filter board of claim 2 , wherein the suppressor section includes at least one varistor and at least one capacitor.

7. The filter board of claim 6 , wherein the at least one varistor and at least one capacitor of the suppressor section are coupled in parallel along at least one transmission path between the current limiting section and the suppressor section.

8. The filter board of claim 6 , wherein the at least one varistor is a metal oxide varistor.

9. The filter board of claim 1 , further comprising a clamping device configured to suppress voltage transients between the received sensed voltage and an earth potential.

10. The filter board of claim 9 , wherein the clamping device is a gas tube.

11. The filter board of claim 9 , further comprising a resistor coupled in series with the clamping device and configured to reduce the current flow through the clamping device.

12. The filter board of claim 4 , further comprising a clamping device configured to suppress voltage transients between the received sensed voltage and an earth potential.

13. An intelligent electronic device (IED), comprising:
a base including at least one slot;
at least one voltage input disposed through the at least one slot of the base;
a filter board configured to filter voltage received via the at least one voltage input and output at least one signal indicative of the received voltage, the filter board coupled to the base; and
a filter box cover including at least one clip configured to enable the filter box cover to be snapped onto the filter board such that the filter box cover protects the filter board.

14. An intelligent electronic device (IED), comprising:
a base including at least one slot;
at least one voltage input disposed through the at least one slot of the base;
a filter board configured to filter voltage received via the at least one voltage input and output at least one signal indicative of the received voltage, the filter board coupled to the base; and
a filter box cover coupled to the filter board such that the filter box cover protects the filter board and routes at least one wire from the base to at least one component of the IED.

15. The IED of claim 14 , wherein the filter box cover includes at least one clip configured to enable the filter box cover to be snapped onto the filter board.

16. The IED of claim 14 , wherein the filter box cover includes at least one aperture to provide a path for the routed at least one wire.

17. The IED of claim 16 , further comprising a second board and a cable, wherein the filter box cover includes at least one second aperture to provide a path for the cable to couple the filter board to the second board.

18. THE IED of claim 14 , wherein the filter box cover includes a plurality of louvers for dissipating heat generated by the filter board.

19. The IED of claim 14 , wherein the filter box cover includes an interior and the filter board is at least partially disposed in the interior of the filter box cover.

20. The IED of claim 14 , wherein the filter board provides power to one or more components of the IED using the received voltage.

21. The IED of claim 14 , wherein the filter board provides power to one or more components of the IED using power received from an auxiliary power source.

22. The IED of claim 14 , wherein the base is coupled to a housing for disposing components of the IED therein.
