Abstract
A current transformer assembly includes a first current transformer, a plug, a first wire and a second wire between the plug and the first current transformer adapted to transmit a measurement of the first current transformer; and a memory chip adapted to store a first scale factor of the first current transformer.
Claims17
A current transformer assembly comprising:
- a first current transformer;
- a plug;
- a first wire and a second wire between the plug and the first current transformer adapted to transmit a measurement of the first current transformer;
- a memory chip adapted to store a first scale factor of the first current transformer;
- and
- a third wire and a fourth wire between the plug and the memory chip.
3 more elements
A system comprising:
- a current transformer assembly comprising a plug, a first current transformer, and a memory chip;
- a power monitor comprising at least one processor and at least one memory, wherein the power monitor is configured to:
- read a first scale factor for the first current transformer from the memory chip,
- receive a first sensor value from the first current transformer,
- compute a second sensor value from the first sensor value using the first scale factor, and
- use the second sensor value to determine information about energy consumption in a building.
