を特徴とするディジタル形保護継電装置。The voltage and current information of the electric power system is sampled and digitized, a predetermined computation is performed on the sampled data using a program-controlled digital computation means using a microprocessor, and the result of the computation is compared with a predetermined set value. In a digital protective relay device that generates a protective output based on the set value, there is a coefficient setter for arbitrarily setting a correction coefficient for the above set value, a non-volatile generation number, and a coefficient set to the above coefficient setting. a writing means for writing a correction coefficient into a predetermined area of the non-volatile memory; prior to the comparison and determination, the correction coefficient is read from the non-volatile memory, the set value is corrected according to the correction coefficient, and the set value is compared based on the corrected set value. A digital protective relay device comprising: means for making a determination.
