<p>PURPOSE: A remote communications method of DPR(Digital Protective Relay) is provided to receive and transmit high capacity fault data regardless of the limit of a data transferring size by omitting the manipulation of assigning an address to each malfunction data block to transmit bulk fault data. CONSTITUTION: A DPR(15) is connected to a remote area monitoring part(11) through a communications network(13). An analog interface(21) receives an analog signal from a potential transformer(12-1) and a current transformer(12-2). The analog interface changes an analog signal into a digital signal and transfers the digital signal to a main processor(23). The main processor includes a processor(23-1), a ROM (23-2), and a RAM (23-3). A digital interface(22) outputs the digital signal.</p> |
