摘要
A 4-WIRE 3-PHASE POWER DISTRIBUTION NETWORK SENSOR FOR MONITORING MINUTE LOAD UNBALANCE AND HARMONIC NOISE. A sensor system for sensing network parameters of 3-phase power distribution network or power line to interpret neutral failure in said power distribution network or power line comprising means for generating stabilized reference signals synchronized to the three phases of said power distribution network or power line and thereby generating inverting neutral voltage with respect to ground and means for determining electronic attribute related to the neutral voltage. The determined electronic attributes are compared in comparator circuits with their predefined set values to interpret the neutral failure in the power distribution network or the power line.
