Description:

Micro-processor based capacitor protection, measurement and control device On-site operation of industrial-grade computer 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

WDR-821A series Microcomputer capacitor protection and control device applied voltage of 66kV and below grade shunt capacitors installed in the protection and monitoring and control..
