Abstract
Systems, apparatuses, and methods are described for calibration of a current transformer. In some examples, one or more electrical elements may be affected in order to set a calibration of the current transformer. A calibration circuit of the current transformer may be permanently or non-permanently affected according to a calibration code in order to set the calibration of the current transformer. For example, one or more fuses may be burned to lock in a certain configuration of the current transformer.
Claims20
An apparatus comprising:
- a first circuit configured to adjust a measurement of an alternating current, the first circuit comprising:
- a switch located in a first electrical pathway between two terminals of the first circuit, wherein the first electrical pathway is configured to provide an electrical connection between the two terminals of the first circuit when the first electrical pathway is in a closed circuit configuration;
- and
- a first electrical element located in the first electrical pathway between the two terminals of the first circuit;
- and
- a second circuit configured to adjust the measurement of the alternating current, the second circuit comprising:
- a fuse located in a second electrical pathway between two terminals of the second circuit, wherein the second electrical pathway is configured to provide an electrical connection between the two terminals of the second circuit when the second electrical pathway is in a closed circuit configuration;
- and
- a second electrical element located in the second electrical pathway between the two terminals of the second circuit;
- wherein the second electrical pathway is configured to be set to an open circuit configuration when the fuse is burned, and the fuse of the second circuit is configured to be burned based on the switch of the first circuit being in an open circuit configuration.
7 more elements
A method comprising:
- setting a first electrical pathway in an open circuit configuration by switching a switch to an open circuit configuration, wherein the switch and a first electrical element are connected to each other between two terminals of the first electrical pathway, and wherein the first electrical pathway is configured to provide an electrical connection between the two terminals when the first electrical pathway is in a closed circuit configuration;
- and
- setting, by burning a fuse and based on the switch being in the open circuit configuration, a second electrical pathway in an open circuit configuration, wherein the fuse and a second electrical element are connected to each other between two terminals of the second electrical pathway, and the second electrical pathway is configured to provide an electrical connection between the two terminals of the second circuit when the second electrical pathway is in a closed circuit configuration.
