Descripción del producto

  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.
