	Transformer (Java 2 Platform SE 5.0)
		This instance may then be used to process XML from a variety of sources and write the transformation output to a variety of sinks.
		This method does not return a default parameter value, which cannot be determined until the node context is evaluated during the transformation process.
		The properties returned should contain properties set by the user, and properties set by the stylesheet, and these properties are "defaulted" by default properties specified by section 16 of the XSL Transformations (XSLT) W3C Recommendation.

	Transformer Basics
		Transformers are often used to convert between high and low voltages, to change impedance, and to provide electrical isolation between circuits.
		Transformers come in a range of sizes from a thumbnail-sized coupling transformer hidden inside a stage microphone to gigawatt units used to interconnect large portions of national power grids, all operating with the same basic principles and with many similarities in their parts.
		Transformers may also be enclosed by magnetic shields, electrostatic shields, or both to prevent outside interference from affecting the operation of the transformer, or to prevent the transformer from affecting the operation of other devices (such as CRTs in proximity to the transformer).

	Transformer Products
		Keeping a transformer painted in the field is important, not only because it extends the operational life of the unit but also because the public expects utilities and industrial facilities to maintain the appearance of equipment installed near their property.
		The insulation power factor of a transformer is the ratio of the resistive current to the total current flowing in the transformer's insulation structure when tested under a sinusoidal voltage and prescribed conditions.
		Many pad-mounted transformer specifications require welded-on covers because bolt-on covers are sometimes considered suspect in terms of their ability to maintain reliable seal integrity and tamperproof security, and prevent contamination of the insulating fluid.

	Transformers
		The transformer by itself is not a complete unit therefore UL recognizes it as a component.
		The further the distance between the fixture and the transformer, the bigger the voltage drop, and this is what causes the fixtures to flicker.
		The key is to select a transformer that is equal to the total of the wattage, or one that is the next step up.

	E.T.E. 3 Phase Transformer Info
		If three phase transformation is need and a three phase transformer of the proper size and turns ratio is not available, three single phase transformers can be connected to form a three phase bank.
		Whenn three single phase transformers are used to make a three phase transformer bank, their primary and secondary windings are conected in a wye or delta conection.
		The X1 lead of transformer B is conected to X1, lead of transformer A, and the X1 lead of transformer B is connected to X2 lead of transformer A, and the X1 lead of transformer C is connected to X2 lead of transformer B. The load is conected to the points of the delta connection.

	Inside Transformers
		If the primary of a transformer carries direct current, which is not resisted by inductance but only by the resistance of the winding, which is always low, it is easy to drive the core into saturation for at least part of the cycle.
		Transformer design is a well-developed subject, and the reader is referred to the many textbooks that treat it.
		Three rules should always be observed in using transformers: first, a voltage greatly in excess of the rating should not be applied to any winding; second, a significant direct current should not be allowed to flow through any winding not designed for it; third, the frequency should not be significantly less than the design frequency.

	Electrical: Energy Efficiency - Introduction to Transformer Losses
		Transformer losses are produced by the electrical current flowing in the coils and the magnetic field alternating in the core.
		The values of transformer losses are important to the purchaser of a transformer who wants to select the most cost-effective transformer for their application.
		Transformer life cycle is defined as the useful life of the asset and is usually assumed to be 30-35 years).

	Overcoming Transformer Losses
		These transformers are traditionally available in either 80°C or 115°C operating temperature rise, as opposed to the standard 150°C rise that represents the majority of low-voltage, 3-phase, dry-type transformer sales.
		Since many transformers are loaded to less than 50% capacity, use of an 80°C rise transformer is often a commitment to higher energy costs—the exact opposite of what was intended.
		K-rated transformer—Unlike standard transformers, which are designed to feed linear loads only and lose capacity when feeding nonlinear loads, K-rated transformers are designed to feed nonlinear loads with harmonic content up to their nameplate rating.

	Electrical: Energy Efficiency - Temperature Rise and Transformer Efficiency
		Transformer temperature rise is defined as the average temperature rise of the windings above the ambient (surrounding) temperature, when the transformer is loaded at its nameplate rating.
		Further, the cause of most transformer failures is a breakdown of the insulation system, so anything that adversely affects the insulating properties inside the transformer reduces transformer life.
		Most transformers are designed to operate for a minimum of 20-30 years at the nameplate load, if properly sized, installed and maintained.

	Power Supplies
		Transformers convert AC electricity from one voltage to another with little loss of power.
		Transformers work only with AC and this is one of the reasons why mains electricity is AC.
		A step-down transformer has a large number of turns on its primary (input) coil which is connected to the high voltage mains supply, and a small number of turns on its secondary (output) coil to give a low output voltage.

	Amazon.com: Transformer: Music: Lou Reed (Site not responding. Last check: )
		Through and through, Transformer is an excellent album, but it starts to weaken as it draws to a close.
		Transformer is Lou Reed's most popular album, and while not necessarily his best (contrary to popular belief), it is nothing short of excellent.
		Transformer is a literate, intelligent and enduring statement of an era and is one of the few albums of the glam-rock movement that has survived with its artistic integrity intact and that still has something to say today.

	Transformer
		A transformer makes use of Faraday's law and the ferromagnetic properties of an iron core to efficiently raise or lower AC voltages.
		It of course cannot increase power so that if the voltage is raised, the current is proportionally lowered and vice versa.
		The ideal transformer neglects losses to resistive heating in the primary coil and assumes ideal coupling to the secondary (i.e., no magnetic losses).

	Amazon.co.uk: Transformer: Music: Lou Reed (Site not responding. Last check: )
		TRANSFORMER built on the stripped-down, quirky pop of LOADED-era VU, infusing it with the androgynous, cheeky glitz of the glam era (the bleached-out fl-and-white cover photo of Reed in eye makeup is a giveaway), not to mention a fair bit of Ronson's guitar muscle.
		But TRANSFORMER's highlights aresome of Reed's best-ever songs: the soaring ditty "Satellite of Love", for instance, the cutting "Vicious", the romantic, yet chillingly melancholic "Perfect Day", and the slice of pop perfection that is "Walk On The Wild Side", complete with shuffling groove, sliding bass, instantly memorable vocal back-ups, and Reed's deadpan talk-singing.
		Transformer is a type of decadent cabaret comparable to Bowie's Alladin Sane, but it is less bleak and much more colourful and engaging.

	Understanding The Basics of Wye Transformer Calculations
		In a wye configuration, three single-phase transformers are connected to a common point (neutral) via a lead from their secondaries.
		The ratio of a transformer is the relationship between the number of primary winding turns to the number of secondary winding turns — and thus a comparison between the primary phase voltage and the secondary phase voltage.
		Now that you understand delta and wye transformer calculations, you can see how important they are to being able to do a quality installation any time you're specifying transformers or considering adding loads to existing transformers.

	Transformer
		Use a matching transformer to raise the impedance seen by the amplifier to something it can comfortably drive (like 4-8 ohms).
		I decided to build a toroid transformer based on the fact that there are lots of good sources for toroid cores, both new and surplus.
		You will find that the power the transformer can transfer is proportional to the square of “B”, the maximum flux density (this is why you want a high flux density ferrite toroid), and “A”, the toroid cross section (this is why you want a physically large toroid).
