Harmonics Compensation 200/400V Active Harmonic Filter Ahf Module Triple Phase

Short Description:

More and more loads are non-linear, introducing harmonics into the power grid and thus significantly impairing the power quality. 3 phase active harmonic filter is an ideal product effectively reduces the unwanted harmonics.

Non-linear loads, by contrast with linear loads, have become increasingly common: frequency converters in drive systems, the large numbers of switch-mode power supplies used in IT and communications equipment, and also more and more in household electronics. Even lighting technology employs mainly non-linear power supplies. Non-linear loads becomes more and more in industrial plants, office buildings, data centers or even private households.

The user can set the parameters so that the active harmonic filter can simultaneously filter out harmonics, dynamically compensate reactive power, compensate for three phase unbalance, and compensate for voltage drop, etc.

Features

3 phase active harmonic filter is a new type of electronic device for dynamic filtering of harmonic wave and reactive power compensation. It can conduct real-time filtering and compensation to harmonic wave (both size and frequency are changed) and dynamic reactive power, and is used to overcome disadvantages of traditional harmonic suppression and reactive compensation methods of traditional filters,thus realizing systematic harmonic filtering function and reactive power compensation function. In addition, it is widely applied into power,metallurgy. petroleum, port, chemical and industrial and mining enterprises.
