请高手翻译以下下面的句子（实在是翻译不下去了）
Care should be taken to fit tuned filters to individual items of equipment connected to the low voltage side of the same distribution transformer in order to avoid problems.Parallel connected filter units for one harmonic order will not have exactly the same resonance frequency due to the tolerances of the components causing problems,for example,due to unequal sharing of the harmonic load and/or to parallel resonances between tuned filters.In such cases it could be useful to use additional contacts to connect together the points between reactors and capacitors of each phase of the filter units for the same harmonic order which are in service.
