S. practices. Greater use is made of gas and pressure relays for transformers, there is more use of complete single-pole tripping and reclosing facilities for ground faults, more underreaching distance relays with remote tripping by carrier, more complete operating records, a greater number of manufacturers in all Europe, but comparatively the same number per country, and greater dependence on international conferences for exchange of ideas. National practices and trends are presented.","PeriodicalId":118797,"journal":{"name":"Transactions of the American Institute of Electrical Engineers.

A hydraulic air compressor replaces the conventional air compressor in the gas-turbine plants so that the turbine can be used to deliver more electric energy, especially during peak loads. The economical application of this system does not depend on a high head between the upstream and downstream levels of natural water, therefore more water power can be economically utilized. The system suggested is flexible, can be installed in different places where convenient, and would help hydroelectric power on a more economical basis. In a case where the installation cost of the conventional hydroelectric plant is high, the hydro-aero-thermal system may be more economical and convenient for both generating and pumping.","PeriodicalId":118797,"journal":{"name":"Transactions of the American Institute of Electrical Engineers.
