Microcomputer Generator Main Protection Set


Computer generator main protection set device On-site operation of industrial-grade computer r computer generator main protection relay protection device for the rely, and in line with conventional experimental test of relay protection instrument, the introduction of the real teaching of our actual experimental device. Experimental setup mock panel wiring diagram, and there are corresponding indicator display, makes the experiment more intuitive display of. Experimental device provides six independent analog outputs, including three-way independence of AC voltage output and three-way independence of AC current output, and have their own precise indication of the corresponding instrument to ensure the completion of the flexibility and accuracy of the experiment Microcomputer-transformer unit protection devices mainly applied to power system large units of various wiring transformer protection. WFB-801A device integrates a generator of all the main protection.
