Harmonic of current
WebHarmonic currents will tend to flow into the system capacitance and this can give rise to overloading of power factor correction capacitors and to the derating of cables. … WebActive Harmonic Filter. The working principle of an active REVCON Harmonic Filter RHF-Active is completely different from any other harmonic solution. Instead of working as a line filter with tuned passive filter circuits, the active solution is connected in parallel and injects harmonics. These injected harmonics are of inversed polarity (180° phase shift) to the …
