Why is it desirable to inject reactive power into a

Why is it desirable to inject reactive power into a transmission system? Ask Question Asked 4 years, 8 months ago. Active STATCOM - can exchange reactive power only; the voltage is much more stable with compensation. The current gets lower through the cable resulting in lower active losses.

Static VAR compensator - Wikipedia

A static VAR compensator is a set of electrical devices for providing fast-acting reactive power on high-voltage electricity transmission networks. SVCs are part of the Flexible AC transmission system device family, regulating voltage, power factor, harmonics and stabilizing the system. A static VAR compensator has no significant moving parts (other than internal switchgear).
