Description:

Computer generator reserve 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

Microcomputer-transformer unit protection devices mainly applied to power system large units of various wiring transformer protection. WFB-802A device integrates a generator of all the reserve protection.

Function :

Zero sequence over voltage protection, Clearance zero sequence current protection, Incomplete-phase protection,

Failure start current distinguishment, Over load(on-load voltage regulation blocking,ventilation starting), Low voltage (memory) over current protection, Over current protection, Negative inverse time over current protection, Negative over current protection, Rotor over load protection, Stator symmetiral over load protection, Over-voltage protection, Under-voltage protection, Low frequency accumulation protection, Sudden adding voltage protection, TV broken protection, Start/shutdown stator ground protection, GPS calibration Fault wave recording, Non-electricity protection.
