Abstract

AN ELECTRONIC UTILITY METER TO MONITOR MAGNETIC FIELDS IN UTILITY METERS AND TO INDICATE THE PRESENCE OF ABNORMALLY LARGE MAGNETIC FIELDS. THE METER COMPRISES MEANS FOR DETECTING CONSUMPTION OF A UTILITY, MEANS FOR INDICATING THE RESULT OF THE DETECTION AND MEANS(20) FOR DETECTING THE PRESENCE OF MAGNETIC FIELD ORIGINATING OUTSIDE THE METER.PREFERABLY, THE MAGNETIC FIELD DETECTION MEANS(20) INCLUDES A DETECTION CIRCUIT(21) WHICH INCLUDES AN INDUCTANCE (L) IN THE FORM OF A COIL WOUND AROUND A FERRITE CORE.FIGURE 1
