Abstract

Apparatus and methods are provided for electrical parameter measurements at points of interest, such as circuit breakers, machines, and the like. The devices which comprise of components that may require corrections, such as the errors induced by, but not limited to, the use of a split core mounted around a current carrier, and hence calibration coefficients are provided based on test, measurements and/or calculations respective of the devices. These coefficients may be stored in a database for retrieval when calibration of measurements received from a measuring device. In one embodiment at least one of the calibration coefficients is stored on the measuring device.
