| Abstract: | By analyzing conduction measurement results of substation on-off operation in second system and low voltage AC power system, characteristics of conduction interference in substation low voltage AC power are given. Frequency properties of insertion loss and property impedance of a few typical power filters are studied by network analyzer. Using immunity testing apparatus, effects of filter and suppression of power filter on electrical fast transience/burst and oscillatory waves are analyzed. Requirement of filter property of substation power filter is given. |
