The paper achieves a study on the reactive power consumption in case of a medium transformers or induction furnaces, which make these consumers. This level depends on the tariff, but often corresponds to a tan ϕ value of (cos φ of ). In the case of MV metering, it is sufficient to raise the power factor to a point where the transformer plus load reactive-power consumption is below the level at which a billing charge is made. For this reason, most of the converters use reactive compensation devices to control reactive power requirement of the converters. Transformers: In order to produce a magnetic field, transformer need reactive power, therefore it absorbs the reactive power. These converters always consume reactive power when they are in operation. In actual DC transmission projects, actual reactive power consumption of the the converter transformer); (2) uncertainty of system operation parameters. Since the no load reactive power consumed by the transformer is also proportional to the square of the excitation current, therefore for practical purpose the no load component of reactive power can be neglected for calculating the total reactive power consumption of the transformer at higher loads. transformer i.e. in the order of %. Since the no load reactive power consumed by the transformer is also proportional to the square of the excitation current, therefore for practical purpose the no load component of reactive power can be neglected for calculating the total reactive power consumption of the transformer at higher loads. transformer i.e. in the order of %.
