The different faults in industrial systems is continuously growing.
It comes more often to problems and failures of control systems and equipment.
In a variety of power grid problems Active filters can help.
FRANKE Elektrotechnik offers different Active filters for each specific need.
We support our customers in the conceptualisation to commissioning.
What is a Active Harmonic Filter used for?
For 3- and 4-wire power networks, up to 50th harmonics
Reactive power compensation
Fast power factor correction.
Balancing loads between phases and unload neutral wire
Reducing flicker values (caused by reactive current)
What is the reason for Harmonics in 3ph. Power Systems?
None linear loads generate harmonics on the grid side!
6 pulse – Line Rectifier (B6), Thyristor – Bridge (SCR), other Loads
Modern loads are the source for harmonics (Current and Voltage)
Non sinusoidel currents generates voltage drops in combination with the line impedance and this is the result for voltage distortion.
