Abstract
Systems, devices, methods, and techniques for self-correcting current measuring are disclosed. Advanced material inductive measuring devices can obtain a reading of a monitored current in a monitored source. The advanced material allows the measuring device to operate at low temperatures disproportionate to saturation levels. Readings by the measuring device that are beyond a top-end limit of the measuring system or otherwise outside of a desired band can be transformed or transposed by employing a transformation to correct the reading to be within an acceptable ratio error band.
Claims20
A system comprising:
- a measuring device to obtain a reading associated with a monitored current in a source to be monitored, the measuring device comprising a thermally stable nano-layered material, the measuring device having a top-end limit, wherein physical characteristics of the measuring device cause readings below the top-end limit to follow a first plot pattern, and wherein the physical characteristics of the measuring system cause readings above the top-end limit to follow a second plot pattern;
- and
- a processing circuit to determine, based on the reading, a measurement of the monitored current, wherein the processing circuit, in response to the reading being above the top-end limit of the measuring system, employs a transformation to determine the measurement of the monitored current.
A system comprising:
- a measuring device to obtain a reading associated with a monitored current in a monitored source, the measuring device comprising a current transformer that includes a thermally stable nano-layered material, and the measuring device having a top-end limit beyond which one or more physical limitations of the measuring device cause the reading to comprise an error outside an acceptable ratio error;
- a processing circuit to, based on the reading associated with the monitored current, determine a measurement of the monitored current, wherein if the reading is beyond the top-end limit of the measuring system the processing circuit is configured to employ a transformation to correct the reading to be within the acceptable ratio error.
