20100152916 | METHOD AND SYSTEM FOR DETECTION OF STANDBY STATUS IN LINEAR AND NON-LINEAR CHARGES CONNECTED TO THE ELECTRICITY MAINS AND AUTOMATIC DISCONNECTION THEREOF - The method permits the detection of ‘standby’ state’ in linear and non-linear loads connected to the power grid and their automatic disconnection, and comprises 4 main stages: a) Detection of the normal operating state of at least one load by means of detection, obtaining the maximum value of the current in said operating state, b) Detection of entry into ‘standby’ mode’ of the at least one load by the means of detection establishing said ‘standby’ state’ when the existing current value obtained in each load is less than a percentage P of the maximum value of the current of each load in normal operating state, c) Start of means of timing at a determined time T for each load when it goes into ‘standby’ mode’, and d) Disconnection of the at least one load and of the means of detection when value T is reached of the means of timing without the at least one load having returned to normal operating state. | 06-17-2010 |
