DIGITAL ELECTRICAL MEASURING INSTRUMENT AND A SYSTEM FOR MONITERING POWER

摘要

The present invention discloses a power monitoring system. In particular, the present invention relates to a digital instrument and a power monitoring system including the same that improve efficiency and stability by duplexing transmission and reception of measurement information between a digital instrument and a higher-level monitoring apparatus as a lower terminal in a power monitoring system. According to the embodiment of the present invention, a storage unit and a communication unit are added to a DI / DO unit included in a digital instrument installed in each facility, and the function is extended. By double-connecting the upper unit with an upper monitoring unit via a separate communication network, It is possible to improve the efficiency and stability of the entire system.
