Abstract

Load shedding system for consumer installations with high power motors. Load shedding system for insulated consumer installations with motors based on the comparison of the speed and/or the variation in the speed over time of the motors with previously adjusted thresholds that disconnect the different motors if their speed and/or variation it does not exceed these thresholds.
