Abstract

Load-shedding relay having two preselected load-shedding thresholds PN, PR. A switch 50 driven by a peak day override relay 60, 62 selects a smaller load-shedding threshold during the peak days period. A signalling D4, D5, 66 advises the user of the operating mode. The crossing of the threshold brings about the charging of a capacitor driving an operational amplifier.
