Types range from fixed and switched capacitor banks to SVC and active SVG\/STATCOM systems, chosen by how fast and how continuously the load varies.<\/p>\n<h3 style=\"margin:28px 0 10px;font-size:1.15em;line-height:1.35;\">What are the main types?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7;\">Fixed capacitor banks (steady base load), automatic switched capacitor banks (stepped, controller-driven), SVC (thyristor-controlled, continuous but generates harmonics), SVG\/STATCOM (active, stepless, fastest), and hybrid systems that combine capacitors with an SVG.<\/p>\n<h3 style=\"margin:28px 0 10px;font-size:1.15em;line-height:1.35;\">What is the difference between a capacitor bank, SVC, and SVG\/STATCOM?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7;\">Capacitor banks correct power factor in steps and respond in seconds. SVC responds in about 2-3 cycles and is continuous but produces harmonics that need filtering. SVG\/STATCOM uses power electronics for stepless, millisecond response and can both supply and absorb reactive power.<\/p>\n<h3 style=\"margin:28px 0 10px;font-size:1.15em;line-height:1.35;\">How fast does each compensator respond?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7;\">Switched capacitors respond in seconds (stepped), SVC in roughly 2-3 cycles, and SVG\/STATCOM in about 10-15 ms. Exact figures depend on the vendor&#8217;s topology and rating.<\/p>\n<h3 style=\"margin:28px 0 10px;font-size:1.15em;line-height:1.35;\">When should I use a dynamic SVG instead of switched capacitors?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7;\">Use dynamic compensation for fast-varying or shock loads (arc furnaces, welders, cranes), for flicker mitigation, and on weak grids, because switched capacitors are too slow and their output drops with voltage while an SVG holds near-constant current.<\/p>\n<h3 style=\"margin:28px 0 10px;font-size:1.15em;line-height:1.35;\">What is a hybrid compensation system?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7;\">A hybrid system uses capacitor banks to cover the bulk, steady reactive demand economically and an SVG to trim the fast, fine, and dynamic component, balancing cost and performance.<\/p>\n<h3 style=\"margin:28px 0 10px;font-size:1.15em;line-height:1.35;\">Does an SVC or capacitor bank work as well as an SVG on a weak grid?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7;\">No. Capacitor and SVC output falls with the square of voltage, so on a weak grid their support weakens just when it is needed.
