Harmonic Filter Resistor : Ready for 1200kV network voltage.
PRINCIPLE
Modern electrical equipment requires a stable voltage supply with low levels of harmonic distortion. However, electrical installations often generate interference causing disturbance to electrical networks. This leads to various problems such as:
- Overheating
- Malfunctioning of control or remote monitoring systems
- High currents in the different phases or neutral lines
- Resonance problems
As a result it is necessary to have harmonic filters. These are basically composed of capacitors and inductors. The addition of a resistor allows:
- Easier filter tuning at installation,
- Widening of the pass band,
- Greater tolerance of temperature changes in the components.
