Electricity Utility

Loads of electricity utility consists of linear loads and non linear loads. The non linear loads for example TV, personal computer, VCD player, microwave and fluorescent lamp using electronics ballast. Loads with non linear characteristics become harmonic current source to electricity utility. Condition prediction used statistic linear comparison based on load power to THDi (Distortion of Harmonic Current). Measurement result using power quality analyzer and etap 4.0 (Fluke 43B) find typical THDi. The calculation and measurement result of PF and THD to loads of electricity utility show the differences less than 5%. However power factor formulation and distortions of harmonic current is valid

One of the problems of electricity quality is harmonics. Harmonic is one ofthe components sinusoidal from one period wave that has the frequency representingmultiple from the fundamental component. Voltage and current distortion caused bynon-linear loads. One of kinds of non-linear loads is Inverter. Harmonic is verydisturbs and harm when exceeding standard limit that appointed. Standard worn asreference in this research is standard IEEE 519-1992, used to voltage limit andmaximum harmonic current.
