变压器

Installation, test and practical measurements of the whole system also have been implemented. Studied the various methods of digital monitoring dielectric loss for transformer bushes: harmonic analysis method. Sine-shape parameters method and integration method, states the principles of the three methods, its computational formula has been inferred and compared. Among them, harmonic analysis method was used to test practically both in lab and on site.
