Abstract

Disclosed herein are embodiments of devices for measuring electrical current and related systems and methods for forming and using such devices. According to certain embodiments devices according to the present disclosure may comprise Rogowski coils. Also disclosed are systems and methods for forming a current measuring device using a bobbin that may allow for the use of a continuous length of wire for all windings associated with the current measuring device. Automated manufacturing techniques may be utilized to facilitate the manufacture of devices for measuring electrical current and/or may reduce the cost of such devices. Various embodiments disclosed herein include the use of a bobbin that may be selectively configured between a linear configuration and a closed configuration. One or more current sensors disclosed herein may be utilized in connection with a motor management relay or other type of intelligent electronic device.
