查询词典 filter factor

LC filter is an important part of this hybrid reactive power dynamic compensation. The parameters of capacitor and inductive winding of LC filter change during operation with the changing surrounding temperature, the self-heating and the insulation ageing of capacitor, etc. During the installation and commissioning, there may exist errors that can deviate the actual parameters and correspondent harmonic oscillation frequency from the designed value and result in filter disarrangement.
