IO-BOX FOR DETECTING LIVE WIRE STATE OF HIGH VOLTAGE CABLE

摘要

PURPOSE: An IO-BOX for heavy electric equipment control is provided to effectively control heavy electric equipment by and to remarkably reduce magnetic contact, an auxiliary contact point, and a cable. CONSTITUTION: A communications unit comprises an IEC61850 server(120). The IEC61850 server receives data through a communications cable for communicating to an IEC 61850 communications protocol. A digital input module(140) inputs the data from one and more first heavy electric equipment. A digital output module(150) outputs the data from one and more second heavy electric equipment. A PT input module measures the value of a high pressure inspection insulator.
