The invention relates to the technical field of high-voltage electrical test and transmission, in particular to a method for electrical equipment field test and characteristic evaluation management. Microsoft 3.5 serves as a .Net frame, and data access, remote interfaces, service logic, data entities and 5UI displaying are achieved in a C/S+B/S system multi-layer architecture. The method has the effects that evaluation management performed on main characteristic test items of a main transformer, a switch, a CT and a PT of a transformer substation is achieved, and evaluation management performed on an arrester, a cable, an isolation switch, a capacitor, an electric reactor, a relay protection device and other devices is achieved; interconnection between test equipment with an USB interface and a computer is achieved, data are uploaded in real time, original recording processes are reduced, reliability of original data is enhanced, the paperless effect of a working site is achieved, a test report can be directly provided, and workloads of a production team are greatly reduced.
