Main Micro-Based Computer Type Transformer Protection Measurement & Control Device Manufacturer,Supplier and Exporter in China
Product Code : EL-ELE-12217
Main Micro-based computer type transformer protection measurement & 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
Microprocessor-based transformer protection device 110kV voltage level applied to the transformer. WBH-811A type device integrates all of a transformer primary protection; the protection device is also able to meet the requirements of substation automation system.
