Abstract
This study was made aiming at energy-saving of a connected line under non-linear load, First, the reporter analyzed the voltage and current wave form of each element in a lag type operating circuit for high pressure mercury lamp to Fourier series. By using the result, the reporter made investigation theoretically of the power distribution of each element in the operating circuit as well as the power factor improvement of input terminal and made experiments, resulting that
(1) It was found that the power of distorted wave such as the third of fifth higher harmonics was transferred between a mercury lamp and a choke coil ballast.
(2) In lighting the high pressure mercury lamp (H 100) by means of a choke coil ballast, the voltage and current characteristics of nonlinear impedance and the characteristics of phase difference angle required to make the power factor of input terminal 1.0 theoretically are mentioned below.
(3) The report describes theoretically the improvement of power factor available only by parallel capacitance of input terminal in lighting the high pressure mercury lamp (H 100) by means of the choke coil ballast, The result corresponds well to actual values.
