	Electric Industry Restructuring Paper #5:
		This is particularly important, because the transmission capacity increases in proportion to the square of the transmission voltage.
		The amount of this loss depends on the length of the transmission, the voltage at which transmission occurs, the size of the conductor, and the manner in which electricity is transmitted.
		American Electric Power is planning to install a 320 MVA unified power flow controller at its Inez Station in eastern Kentucky to fully utilize the high capacity of this new 138 kV line [14].

	Static VAr compensator - Wikipedia, the free encyclopedia
		A static VAr compensator (or SVC) is an electrical device for providing fast-acting reactive power compensation on high-voltage electricity transmission networks.
		Typically an SVC comprises a bank of individually switched capacitors in conjunction with a thyristor-controlled air- or iron-cored reactor.
		The main advantage of SVCs over simple mechanically-switched compensation schemes is their near-instantaneous response to changes in the system voltage.

	Flexible AC transmission system - Wikipedia, the free encyclopedia
		Flexible Alternating Current Transmission System (FACTS) is a static equipment used for the AC transmission of electrical energy.
		It is meant to enhance controllability and increase power transfer capability.
		FACTS is defined by the IEEE as "a power electronic based system and other static equipment that provide control of one or more AC transmission system parameters to enhance controllability and increase power transfer capability."

	PSERC Document > 2004 Publications
		Electricity markets pose unique problems to detection of market power due to the properties of electricity: it cannot be stored, which implies that the amount of energy supplied must always equal the amount demanded, and it must obey the laws of physics.
		Power system overall load relative to operating limits is a key factor affecting the risk of cascading failure.
		Transmission congestion management can be implemented in the more centralized point-to-point approach, as in New York state, where derivative transmission congestion contracts (TCCs) are traded, or in the more decentralized flowgate-based approach.

	::: COIL INNOVATION :::
		Air-core dry-type reactors are mainly employed in electric power transmission and distribution systems as well as in electric power systems of electrical plants.
		With the ongoing development of electrical power technology, especially through the increased use of semiconductors in electric power systems, the requirements of power inductors have changed during the last decades.
		The application spectrum for air-core dry-type reactors has been extended, caused by economic advantages of the air-core reactor technology in comparison with iron-core reactors and by the benefits of the linear characteristics of air-core reactors.
