Single-phase power production

The general tendency of the electric power supply industry is toward the centralization of power stations, embracing a variety of loads. In order to be consistent with this development ft is highly desirbale that power stations be standardized in essential features, so that they may combine their resources toward the ideal arrangement. The production of single-phase power should not interfere with this general scheme. Looked at from this standpoint, single-phase power can best be produced from polyphase systems. Means are suggested for producing single-phase power without interfering with the broad usefulness of the power station. The mode of operation and theory of phase converters is discussed with particular reference to its adaptability for permitting single-phase power to be derived from polyphase circuits.
