Description:

Computer line protection 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 Computer line protection and control devices to achieve the low-voltage circuit protection and monitoring and control functions, mainly for 110kV and below levels of voltage levels of lines and feeder. Function : Three-section phase distance protection, Two section current protection after TV break, Double loop lines continue fast motion's protection, Unsymmetrical fault continue fast motion's protection, Four section current protection, Three-phase singe-shot reclosing, Manual synchronization, Low Frequency (LF) load shedding protection, Fault wave recording, GPS calibration.
