IPC: H02H3/28
Filed: 1993-11-11
Abstract: PURPOSE:To prevent erroneous detection at a reception terminal by mutually transmitting ON/OFF data of a device from a power transmission terminal to the reception terminal by software processing of arbitrary ready bit pattern. CONSTITUTION:A/D converters 2A and 2B input system current, perform the A/D conversion, and sample the amount of input electricity at the same timing. Transmission parts 3A and 3B input information which is obtained by generating the state of current differential protection relay devices 1A and 1B by software at operation parts 4A and 4B simultaneously with the output of the A/D converters 2A and 2B to produce a transmission format. An arbitrary ready bit pattern is produced from a transmission format produced by software.
