Due to extensive use of energy saving lamps and lanterns,
computers, convertible frequency air-conditioner,
variable-frequency motor, UPS, EPS and loads like these kind in
places such as commercial buildings, shopping malls, big
stores/supermarkets, office buildings, gymnasiums, securities
finance companies, computer rooms and factory production line,
massive 3rd harmonics is being produced although we can save energy
by these loads for certain percent.
 The harmonics not only pollutes the network, making power
quality worse but also affects the normal function of sensitive
electronic equipment. Besides, 3rd harmonic is zero sequence
harmonic, which would superimpose on the neutral line, and
eventually have over current risk, it will pose potential safety
hazard to equipment and transmission lines and easily cause fire
disaster.Â
