एडीएफ गतिशील परीक्षण बिस्तर बढ़ाता है (COMSYS अटल बिहारी)

पृष्ठभूमि

The development department within a major european plant owns several test benches to test certain components in their products during the development phase. Different test conditions can be programmed, giving the test bench extremely dynamic properties.

चुनौती

Two parts of the test bench are connected to the same transformer. The load is very dynamic and the amplitude of the load current can change from zero to its maximum in approximately 100 एमएस. Both parts of the test bench could not be run at the same time, because of the high harmonic disturbances and voltage notches up to 25 %. Apart from exceeding the limits in EN61000-2-4, this also caused serious delay in the testing facility.

ADF Active Filters from Comsys

The owner of the facility installed equipment from COMSYS अटल बिहारी to compensate the disturbances. Two ADF P300W-200/480 and one ADF P200W-100/480 were installed to compensate all frequencies up to the 100th harmonic order. The एडीएफ P300 series can be used to compensate lower harmonics and the ADF P200 series can compensate the higher order harmonics and interharmonics. The एडीएफ सक्रिय फिल्टर units were configured to share the load, the P200 working on higher orders only. The result was extremely short response times and much lowered disturbances of the load.

परिणाम

Voltage notches could be reduced to 10 % and all harmonics could be lowered to the requested level regarding to EN61000-2-4. The usage of both test benches is now possible and surrounding problems that had been linked to the poor power quality where solved.
