Title: The Innovations of Erich Siegfried Friedlander
Introduction
Erich Siegfried Friedlander is a notable inventor based in Birmingham, GB. He has made significant contributions to the field of electrical engineering, particularly in the development of saturated reactors. With a total of three patents to his name, Friedlander's work addresses critical challenges in harmonic compensation and reactor design.
Latest Patents
Friedlander's latest patents include innovative designs for saturated reactor arrangements. One of his inventions is a saturated reactor adapted for direct connection to an EHV line, which serves as a combined reactor and transformer. This invention effectively addresses the issue of earthing the primary winding star point, which would typically short circuit the 3rd harmonic. By utilizing a series connection of primary coils coupled to three limbs with fluxes spaced at 40 degrees, Friedlander ensures that 3rd harmonic voltages cancel in the series primary windings. Additionally, he has developed a saturated reactor of the treble-tripler type, where groups of 3-phase windings are connected in series to produce multiple flux phases in respective core limbs. This design allows for harmonic compensation while maintaining a low zero-sequence impedance, enabling the star point to be earthed without disrupting the reactor's harmonic compensation.
