Quality of power is becoming ever more important for both suppliers and users, as the number of devices that may feed harmonics in power systems is increased, resulting in higher line losses, interferences and resonances
Harmonic filter resistors that are also known as damping resistors, with capacitors and inductors make up harmonic filters.
While the LC filters let the fundamental frequency through, by clearing all the spurious frequencies, the harmonic currents into heat.
The information that is needed for design :
- Nominal voltage,
- Current or power,
- Ohmic Value (with tolerance in %)
Application areas ;
- HVDC networks,
- Electrical induction furnaces
