ZDDQ SVG/STATCOM is a modular system from 6kv to 35kv, supplies reactive power to distribution grids with high regulating dynamics, and carries out regulating tasks such as voltage regulation or influencing the flow of reactive power.

Medium voltage Static Var Generator(STATCOM) is a voltage regulating device. It 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.
