The programmable transducers can be used in the field of motor or generator protection. To overcome the error of existing system like overvoltage, under voltage and under frequency self aided programmable transducers are used. C based program is to be developed to interface the transducers and generator tripping device to the computer. The output devices are interfaced with the computer through specially designed drive circuits to energize the trip circuit of motor in case protection acts. The drive circuits consists of opto-coupler (for isolation purpose), switching transistors and PCB mounted small relays. The input circuit comprises of Transducers & A/D converter, the output circuit comprises of driving circuits for feeders. Audible alarms also can be generated through computer with the aid of buzzer circuits. The input and the output circuits are connected to the PC through an Interfacing card through pc printer port. All the transducers are connected to the PC through an A/D converter.
