It allows the National Company of Electricity (SNEL) to fix a power in kW subscribers, after determining their consumption. If a subscriber exceeds the subscribed or contracted power, electric power is cut off for five minutes. Upon resumption, if the subscriber has not decreased its consumption in less than a second, electric power is interrupted again; interruptions will not cease until the subscriber will not reduce consumption. http://pubs.sciepub.com/joe/5/1/1/joe-5-1-1.pdf power limiter active power meter
