Abstract

PURPOSE: To make it possible to measure static characteristics and dynamic characteristics of a noise filter with commercial frequency current superposed, by connecting a blocking coil in series to an input line and output line and a transformer in parallel to them.
CONSTITUTION: For a measurement in normal mode, blocking coils 1 are connected in series to input-side line 12 and output-side line 12' of noise filter N respectively. Further, the secondary high-frequency output of transformer 3 connected to high- frequency oscillator 10 is transmitted to the input of noise filter N through coupling capacitor 2 by way of input-side line 12. The output of noise filter N, on the other hand, is led from output-side line 12' to the secondary side of transformer 3 via coupling capacitor 2 and level meter 11 measures its level. For a measurement in common mode, a high-frequency output is led out of matching transformer 5 and level meter 11' measures its level.
