Harmonic investigation of electronic ballast and other commonly used electrical equipment / Zulkifle Omar
A harmonic can be defined as a sinusoidal of a periodic wave or quantity having a frequency that is an integral of the fundamental frequency. Harmonics generation can lead to serious power quality problem if it is not reduced to acceptable level. Electronic components content of modern electrical lo...

| Summary: | A harmonic can be defined as a sinusoidal of a periodic wave or quantity having a frequency that is an integral of the fundamental frequency. Harmonics generation can lead to serious power quality problem if it is not reduced to acceptable level. Electronic components content of modern electrical loads contribute to serious harmonics injection to the main supply line. Recent energy audit suggested using electronic ballast in fluorescent light fitting. The objective of this project is to make comparison how serious is the harmonics due to electronic ballast with other commonly used equipment. The test was done using five different brand of electronic ballast and five different type of electrical equipment such as printer, computer brand A, computer brand B, video player and television. The result obtained indicated most equipment's generating high harmonic contents. |
