Resolution
Thermal protection of a motor can be accomplished by using various protection elements. ANSI 49 provides over-current protection based on the magnitude of current, both past and present. The SEPAM 49RMS element uses current magnitude to model the heating effect the current has on the motor windings. The attached doc provides a detailed description of this protection function.
