Energy-saving: when the dynamometer running, it needs a large motor - generator to set matching, and the inverter can running in four-quadrant by using intelligent dynamometer dedicated feedback device, so that the dynamometer on the one hand back power to the grid, on the other hand to obtain reactive current from the power grid.

Reactance at rated load under normal operation of long-term time, that is, reactor life. Reactor by the manufacturer of its useful life determined by material. Manufacturing Reactor Materials Metal Materials has two major categories of materials and

As China's 500kV power system development, as well as the electrification of railways and the construction of large-scale iron and steel base, a large hub at substations in the need to install a static compensator trends are becoming evident. Static

The expansion of grid capacity, making the system short-circuit rated capacity increased rapidly. Such as low voltage at 500kV Substation 35kV side, the biggest three-phase RMS symmetrical short-circuit current close to 50kA. Transmission lines
