【Abstract】 The article introduces a kind of measuring device for shipping generator’s power designed by analog multiplier, which not only simplifies the circuit structure and promote the measuring precision, but checks the generator’s counter power by the analo multiplier, and supplies the protection signal as well. It is useful to simplify the structure of the shipping power station and control of the computer.更多还原
