In an electric power transmission grid system, switchyard reactors are large inductors installed at substations to help stabilize the power system. For transmission lines, the space between the overhead line and the ground forms a capacitor parallel to transmission line, which causes an increase in voltage as the distance increases.
Between the generator and the final consumer, the voltage may be transformed several times. [25] The three main types of substations, by function, are: [26] Step-up substation: these use transformers to raise the voltage coming from the generators and power plants so that power can be transmitted long distances more efficiently, with smaller ...
Distribution substations are located near to the end-users, or customers, of the power. The transformers at these stations lower the voltage of power to make it suitable for use by customers.
A 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.
These substations may consist of two to eight or more primary transformers connected to the same secondary bus to provide reliable facility power. Examples of such single facilities include airports, hospitals , major data processing centers (especially those using uninterruptible power supplies ), and sports arenas that regularly broadcast ...

The inductive reactance is chosen to be low enough for an acceptable voltage drop during normal operation, but high enough to restrict a short circuit to the rating of the switchgear. The amount of protection that a current limiting reactor offers depends upon the percentage increase in impedance that it provides for the system.
In the UK Crane Rental industry in the UK, which is one of the most highly developed crane rental industries in the world, special regulations for health and safety and rental procedures are in place. These are maintained as the CPA regulations. [1] In Europe, European Rental Association is the trade body representing the equipment rental industry.
