Within a major leading edge manufacturing company, a test bed put extreme demands on the power supply network. このケーススタディで, an ADF installation compensates harmonics up to the 100th order resulting in significant reduction of notching.
背景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. 挑戦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 MS. 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 %. EN61000-2-4 の制限を超えることは別として, これにより、検査施設に重大な遅れが生じました. ソリューション -
