Abstract

A system for modifying the functionality of intelligent electronic devices installed and operating in the field is disclosed. Each of the intelligent electronic devices operates with a software configuration to monitor electrical energy. A copy of the software configurations may be maintained in a database. Changes to the operation of one or more of the intelligent electronic devices may be made as a function of modifications to the database.

Claims

1. A method of maintaining integrity of data collection in an intelligent electronic device operated in the field to monitor electrical energy, the method comprising:

operating a first intelligent electronic device at a location to monitor electrical energy and collect data related thereto;

operating a second intelligent electronic device at the location to monitor the same electrical energy and collect data related thereto;

transferring the data collected by the first intelligent electronic device over a network to a database;

terminating the operation of the first intelligent electronic device to perform maintenance of the first intelligent electronic device;

activating the first intelligent electronic device following the maintenance to again monitor electrical energy at the location and collect additional data related thereto;

transferring the data collected by the second intelligent electronic device to the database; and

from the database, transferring the data from the first intelligent electronic device and the data from the second intelligent electronic device over the network to be stored in the first intelligent electronic device in conjunction with the additional data.

2. The method of claim 1, wherein transferring the data collected by the first intelligent electronic device and the second intelligent electronic device comprises transferring data to the database, wherein the database is located within the second intelligent electronic device.

3. The method of claim 1, wherein transferring data collected by the first intelligent electronic device and the second intelligent comprises transferring data to the database, wherein the database is located within a server communicatively coupled with the network.

4. The method of claim 3, wherein transferring data collected by the second intelligent electronic device comprises transferring data over the network to the server.

5. The method of claim 1, further comprising removing the second intelligent electronic device from service.

6. The method of claim 1, wherein operating the second intelligent electronic device comprises:

transferring a software configuration operating in the first intelligent electronic device over the network to the second intelligent electronic device; and

operating the second intelligent electronic device with the software configuration.

7. The method of claim 1, wherein operating a second intelligent electronic device comprises electrically replacing the first intelligent electronic device with the second intelligent electronic device.

8. The method of claim 7, wherein activating the first intelligent electronic device comprises electrically replacing the second intelligent electronic device with the first intelligent electronic device.

9. The method of claim 1, wherein activating the first intelligent electronic device following the maintenance comprises combining, within the database, data transferred to the database from the first intelligent electronic device with data transferred to the database from the second intelligent electronic device.

10. The method of claim 1, wherein activating the first intelligent electronic device following the maintenance comprises combining within the first intelligent electronic device data transferred to the database from the first intelligent electronic device with data transferred to the database from the second intelligent electronic device.

11. The method of claim 1, wherein operating a first intelligent electronic device at a location to monitor electrical energy further comprises:

applying power to the first intelligent electronic device;

executing a first portion of a software configuration stored in the first intelligent electronic device;

retrieving a second portion of the software configuration from elsewhere in the network as a function of instructions within the first portion of the software configuration; and

executing the first and second portions of the software configuration within the first intelligent electronic device.

12. The method of claim 1, wherein transferring the data from the first intelligent electronic device and the data from the second intelligent electronic device over the network comprises the initial step of deleting data transferred from the second intelligent electronic device that is redundant to the data transferred from the first intelligent electronic device, and appending any remaining data transferred from the second intelligent electronic device to the data transferred from the first intelligent electronic device.

13. The method of claim 1, further comprising the first intelligent electronic device receiving from the network the data transferred from the database, the first intelligent electronic device deleting data transferred from the second intelligent electronic device that is redundant to the data transferred from the first intelligent electronic device and the additional data, and the first intelligent electronic device appending any remaining data transferred from the second intelligent electronic device to the data transferred from the first intelligent electronic device and to the additional data.

14. The method of claim 1, further comprising the first intelligent electronic device receiving the data transferred from the database, deleting that portion of the data transferred from the database that already exists in the first intelligent electronic device, and appending the remaining data transferred from the database to the additional data collected by the first intelligent electronic device.

15. The method of claim 1, further comprising the first intelligent electronic device receiving the data transferred from the database, deleting that portion of the data transferred from the database that already exists in the first intelligent electronic device, and the intelligent electronic device maintaining the remaining data transferred from the database in one data set and the additional data collected by the first intelligent electronic device in another data set.

16. A method of maintaining integrity of data collection in an intelligent electronic device operating in the field to monitor electrical energy, the method comprising:

operating a database to store power parameter related data;

receiving and storing in the database power parameter related data from a first intelligent electronic device operable with a software configuration to measure power parameters of a power conductor and collect data related thereto;

storing the software configuration in the database;

downloading the software configuration to a second intelligent electronic device;

receiving and storing in the database power parameter related data from the second intelligent electronic device operable with the software configuration to measure power parameters of said power conductor and collect data related thereto;

removing from service and then later returning to service the first intelligent electronic device, while the second intelligent electronic device is operable; and

after the first intelligent electronic device is returned to service, downloading to the first intelligent electronic device the stored power parameter related data received from the first intelligent electronic device, and the stored power parameter related data received from the second intelligent electronic device.

17. The method of claim 16, where downloading to the first intelligent electronic device comprises the server combining the stored power parameter related data received from the first intelligent electronic device, and the stored power parameter related data received from the second intelligent electronic device by eliminating redundant data prior to the download.

18. The method of claim 16, further comprising, after the download is complete, the first intelligent electronic device combining the downloaded power parameter related data of the first intelligent electronic device, and the downloaded power parameter related data of the second intelligent electronic device by eliminating redundant data.

19. The method of claim 16, further comprising, after the download is complete, the first intelligent electronic device operating with the software configuration to measure power parameters of said power conductor and collect additional data related thereto, the first intelligent electronic device operable to append the additional data to the downloaded data.
