The KEB harmonic filter is a new innovative solution, which can be already
assigned in the planning phase into the electrical system. The harmonic filter
enables the compliance of growing international standards to reduced harmonic
components.
The following belong to this standards:
- IEEE 519-1992 (USA)
- G5/4 Engineering Recommendation (GB)
- EN 610003-4 and EN 610003-12 (European Standard)
- EN 12015 (European lift norm)
- AS 2279 (Australian)
- COP, supply rules (Hongkong)
- Quality of Electric Energy Supply, Harmonics in Public Supply Networks
(China)
The following advantages are given by means of the special structure of the
harmonic filter:
- optimal filter effect
- compact structure, small space requirements for installation
- installation solution ready-to-connect
- clear reduction of the capacitive current during no-load operation
- no tendency to oscillation during load change
- significant smaller voltage drop compared to mains choke
- Increase of the inverter lifetime by means of the trapezoidal output voltage
and the square-wave current connected with it
- Reduction of THDI to < 8%
- optional THDI < 15%; PWHD < 39%
- optional THDI < 5% (extreme requirements)
- large power range because parallel connection of filter modules is possible
- very high efficiency
The reduction of the THDI to the indicated value of < 8% supposes a VDE conform
public supply system with a max.preloading of THDU = 2% and a ratio of short-
circuit power to connected power RSG = 66 min.
