A rotating coil  in a magnetic field tends to produce a sine-wave voltage. CH Free format text: Verfahren zum Herstellen eines Elektroisolationsmaterials, Elektroisolationsmaterial sowie elektrische Maschine. Modular converter for converting the electric power produced by aerogenerators, and wind-power plant that uses said converter.
For the same mechanical load, the armature current varies with field excitation over a wide range and so causes the power factor also to vary accordingly. Increasing the device’s field excitation results in its furnishing synchrlne power measured in units of var to the system.
Fompensateur legal event code: They will not produce excessive voltage levels and are not susceptible to electrical resonances. The magnitude of Vg depends on the excitation current Ie and the speed of rotation, and as the latter is fixed, Vg depends only on Ie.
A recent development in the electrical insulation systems of generators and transformers. Rotating electrical machine having rotor and stator cooled by compensareur of heat pipes.
Brid ged polyolefine insulating hightension cable having outer semiconductor layers which can be treated off easily. Kind code of ref document: Cooling and insulating system for extra high voltage electrical machine with a spiral winding.
WOA1 – Compensateur synchrone – Google Patents
The variations of I with excitation are known as V curves because of their shape. However, synchronous machines have higher energy losses than static capacitor banks. Asynchronous conversion method and apparatus for use with variable speed turbine hydroelectric generation.
A synchronous machine running without mechanical load and supplying or absorbing reactive power to or from a power system. Glossaries and vocabularies Access Translation Bureau glossaries and vocabularies.

If Ie is critically adjusted to a value Ie0, Vg will be equal and opposite to Vs, and the current in the stator Is will be zero. If the machine is considered to be ideal, with no mechanical, magnetic, or electrical losses, its equivalent circuit will be an AC compenszteur in series with the winding inductance L of the stator.
ES Free copensateur text: Spulenwicklung von Wechselstrommaschinen, die sehr starke Stroeme fuehren, mit ringfoermigen Verbindungsleitern.
Star connected air gap polyphase armature having limited voltage gradients at phase compdnsateur. Large installations of synchronous condensers are sometimes used in association with high-voltage direct current converter stations to supply reactive power to the alternating current grid.
Turbine generator stator end winding support assembly with decoupling from the core. In between, the current has minimum value corresponding to a particular excitation see graph on right.
For both under and over excited motors, the power factor p. Verfahren und Einrichtung zum Betrieb von Einphasenbahnfahrleitungen, die von mindestens zwei Speisepunkten aus gespeist werden. Reactive ssynchrone from a capacitor bank decreases when grid voltage decreases, while a synchronous condenser can increase reactive current as comepnsateur decreases.
Country of ref document: Planar insulator for electrical machine or appts. When connected to a circuit some current will flow depending on how the voltage on the system is different from this open-circuit voltage.
Method of joining two cables with an insulation of cross-linked polyethylene or another cross linked linear polymer. Load compensation in distance protection of a three-phase power transmission line.
A1 Designated state s: The added current flowing to supply reactive power creates additional losses in the power system. Dynamoelectric machines including metal filled glass cloth slot closure wedges, and methods of making the same.
Passageway structure for liquid coolant at gun and transformer ends of welding cable having novel internal surface bearing for alternate polarity strands. This corresponds to the minimum in the curve shown above.
In electrical engineeringa synchronous condenser sometimes called a synchronous capacitor or synchronous compensator is a DC-excited synchronous motorwhose shaft is not connected to anything but spins freely.
GR Free format text: DE Ref legal event code: In a practical machine with losses, the equivalent circuit will contain a resistor in parallel with the terminals to represent mechanical and magnetic losses, and another resistor in series with the generator and L, representing copper losses in the stator.
The phase of armature current varies with field excitation.
