Implementation of Signal Defects Caused by The Effect of Harmonics on The Use of Electricity Loads

Harmonic problems for the electricity network can be classified into two types, instant effects and long-term effects. Immediate effect problems are related to interference problems for communication systems, malfunction or interference causes degradation of more sensitive equipment and devices. Its long-term effects are thermal properties and are associated with additional losses in distribution and overheating, resulting for a reduction in the average life of the equipment. This research wants to prove the change for the shape of the load current signal, who have a signal defect and there is a decrease for the power factor value because of the influence of load harmonics. The method used is experimental. For fluorescent lamp the voltage and current phase difference is 69.8 °, the bulb lamp the voltage and current phase difference is 0 °. The rated power factor is 0.34 for fluorescent lamp, 1.0 for bulb lamp and no measurable power value for LED. The fluorescent lamp are included in the non-linear load which causes harmonics to occur, resulting in a signal defect for the load current.
