More harmonics will cause harm to the electrical system, loss of power, and damage to electrical equipment. Harmonics are periodic, sine waves and are integer multiples of the fundamental frequency (50 or 60 Hz). These components when added to the basic sine wave (50Hz) will cause distortion, distortion of the sine wave.<\/span><\/p>\n<p><span style=\"font-family: 'times new roman', times, serif; font-size: 120%; color: #000000;\"><strong>The cause of wave interference is as follows:<\/strong>Harmonic waves are generated by nonlinear loads such as computers, uninterruptible power supplies, inverters, and fluorescent lamps.<\/span><\/p>\n<p><span style=\"font-family: 'times new roman', times, serif; font-size: 120%; color: #000000;\"><strong>The harmful effects of harmonic waves are as follows<\/strong><\/span><\/p>\n<ul>\n<li><span style=\"font-family: 'times new roman', times, serif; font-size: 120%; color: #000000;\">Harmonic waves can create apparent power, which increases the overall power consumption, energy losses, and incurs additional electricity costs\u00a0<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif; font-size: 120%; color: #000000;\">Harmonic waves have the potential to increase temperature, leading to overheating, wire and equipment damage, and posing serious risks to the power grid system.\u00a0<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif; font-size: 120%; color: #000000;\">Harmonic waves can cause damage to power factor correction capacitors.\u00a0<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif; font-size: 120%; color: #000000;\">Harmonic waves can introduce disturbances into the electrical system and control systems.
