Static Var Generator Suppliers,MV/HV SVG/STATCOM For Sale is based on a power electronics voltage source converter (VSC) and can act as either a source or sink of reactive AC power. It is a member of the flexible AC transmission systems (FACTS) family which detects and instantly compensates for voltage fluctuations or flicker, as well as controls power factor.
How do electricity transformers work? - Explain that Stuff· How does a transformer work? A transformer is based on a very simple fact about electricity: when a fluctuating electric current flows through a wire, it generates a magnetic field (an invisible pattern of magnetism) or "magnetic flux" all around it.The strength of the magnetism (which has the rather technical name of magnetic flux density) is directly related to the size of the electric current.

Electrical substation - Wikipedia substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.
