<p>A digital current differential relay system provided with a signal converter whereby current data is converted into the one having a shortened bit pulse length based on a relation and transmitted, and provided with a signal restoring device whereby received data is converted inversely into current data having the original bit pulse length, which enables the relay characteristic to be affected scarecely, even if the transmitted data is of 12 bits in data length or the data is the one corresponding to 16 bits in data length, by shortening the bit pulse length with the signal converter and transmitting at the transmission side and by restoring the bit pulse length to the original one with the signal restoring device at the reception side.</p> |
