active compensators (e.g., synchronous condensers, static var compensators, static synchronous compensators that can be either sources or sinks of reactive power; regulating transformers (e.g., tap-changing transformers).
In Electrical Engineering, a static VAR compensator (SVC) is a set of electrical devices for providing fast-acting reactive power on high-voltage electricity transmission networks. [ 1 ] [ 2 ] SVCs are part of the flexible AC transmission system [ 3 ] [ 4 ] device family, regulating voltage, power factor, harmonics and stabilizing the system.
In Electrical Engineering , a static synchronous compensator (STATCOM) is a shunt-connected, reactive compensation device used on transmission networks. It uses power electronics to form a voltage-source converter that can act as either a source or sink of reactive AC power to an electricity network. It is a member of the FACTS family of devices.
Metal expansion joints (also called compensators) are compensating elements for thermal expansion and relative movement in pipelines, containers and machines. They consist of one or more metal bellows , connectors at both ends, and tie rods that depend on the application.
Static synchronous series compensator. A static synchronous series compensator (SSSC) is a type of flexible AC transmission system which consists of a solid-state voltage source inverter coupled with a transformer that is connected in series with a transmission line. This device can inject an almost sinusoidal voltage in series with the line.

So, for people like me, whose nerves don't get calmed by facts and numbers, just know, your feelings are valid. Flying is only going to get safer. Getty Stock Photo. Air traffic control tower.
The main principle in PHC is to store the energy from the external forces influencing the system and dissipate them or reapply them later.Shock absorbers or drill string compensators are simple forms of PHC, so simple that they are normally named heave compensators, while "passive" is used about more sophisticated hydraulic or mechanical systems.
