Abstract

A system and method for an isolation transformer boost system. The system includes an isolation transformer, a sensor, and an electronic processor coupled to the sensor. The electronic processor configured to receive an electrical characteristic measurement from the sensor, compare the electrical characteristic measurement to a predetermined threshold, and activate an electrical characteristic boost when the electrical characteristic measurement is below the predetermined threshold.

First claim

What is claimed is:

1. An isolation transformer boost system, the system comprising:
an isolation transformer including a primary winding and a secondary winding;
a contactor coupled to a voltage tap of the secondary winding;
a sensor; and
an electronic processor coupled to the sensor, the electronic processor configured to:
receive, from the sensor, an electrical characteristic measurement;
compare the electrical characteristic measurement to a predetermined threshold; and
activate an electrical characteristic boost when the electrical characteristic measurement is below the predetermined threshold, wherein activating the electrical characteristic boost includes actuating the contactor;

wherein while the system is operating, the electronic processor is configured to activate the electrical characteristic boost when the electrical characteristic measurement is below the predetermined threshold for a first predetermined time period, and deactivate the electrical boost when the electrical characteristic measurement is above the predetermined upper limit threshold for a second predetermined time period;
wherein the system is configured to run in one of a plurality of modes of operation, wherein the one of the plurality of modes of operation is selected from a group consisting of an automatic mode, a manual mode, and a programming mode; and
wherein the automatic mode further includes a static mode and a dynamic mode, wherein while the system is running in the static mode, the electronic processor is configured to activate the electrical characteristic boost when the system is initially powered on and while the system is running in the dynamic mode, the electronic processor is configured to automatically affect the electrical characteristic boost while the system is operating.

2. The system of claim 1 , wherein the predetermined threshold is at least one selected from a group consisting of 190 V, 195 V, 200 V, 205 V, 210 V, 215 V, and 220 V.

3. The system of claim 1 , wherein the electronic processor is further configured to provide a wireless access point.

4. The system of claim 1 , wherein the electronic processor is further configured to connect to a wireless network.

5. The system of claim 4 , wherein the electronic processor is further configured to automatically transmit a status update regarding the system to a remote server.

6. The system of claim 1 , wherein the electrical characteristic measurement is a voltage measurement and the electrical characteristic boost is a voltage boost.

7. The system of claim 1 , wherein actuating the contactor includes disconnecting a connection from a second voltage tap and establishing connection to the voltage tap.

8. The system of claim 1 , wherein the secondary winding includes the second voltage tap.

9. A method of boosting an electrical characteristic of an isolation transformer of an isolation transformer system, the isolation transformer having a primary side and a secondary side, the method comprising:
receiving, from a sensor, an electrical characteristic measurement;
comparing the electrical characteristic measurement to a predetermined threshold; and
activating an electrical characteristic boost when the electrical characteristic measurement is below the predetermined threshold, wherein activating the electrical characteristic boost includes actuating a contact coupled to a voltage tap of the secondary side of the isolation transformer;
wherein while the isolation transformer system is operating, the electronic processor is configured to activate the electrical characteristic boost when the electrical characteristic measurement is below the predetermined threshold for a predetermined time period, and deactivate the electrical boost when the electrical characteristic measurement is above the predetermined upper limit threshold for a second predetermined time period;
wherein the system is configured to run in one of a plurality of modes of operation, wherein the one of the plurality of modes of operation is selected from a group consisting of an automatic mode, a manual mode, and a programming mode; and
wherein the automatic mode further includes a static mode and a dynamic mode, wherein while the system is running in the static mode, the electronic processor is configured to activate the electrical characteristic boost when the system is initially powered on and while the system is running in the dynamic mode, the electronic processor is configured to automatically affect the electrical characteristic boost while the system is operating.

10. The method of claim 9 , wherein the predetermined threshold is at least one selected from a group consisting of 190 V, 195 V, 200 V, 205 V, 210 V, 215 V, and 220 V.

11. The method of claim 9 , the method further comprising creating a wireless access point.

12. The method of claim 9 , the method further comprising connecting to a wireless network.

13. The method of claim 12 , the method further comprising automatically transmitting a status update regarding the system to a remote server.

14. The method of claim 9 , wherein the electrical characteristic measurement is a voltage measurement and the electrical characteristic boost is a voltage boost.

15. The method of claim 9 , wherein actuating the contactor includes disconnecting a connection from a second voltage tap and establishing connection to the voltage tap.

16. The method of claim 9 , wherein the secondary winding includes the second voltage tap.
