In this context of changing and challenging market requirements, Gas Insulated Substation GIS has found a broad range of applications in power systems for more than two decades because of its high reliability, easy maintenance and small ground space requirement etc. SF6 has been of considerable technological interest as an insulation medium in GIS because of its superior insulating properties, high dielectric strength at relatively low pressure and its thermal and chemical stability. SF6 is generally found to be very sensitive to field perturbations such as those caused by conductor surface imperfections and by conducting particle contaminants. The presence of contamination can therefore be a problem with gas insulated substations operating at high fields.

Basic concept of GPS[ edit ] This section needs additional citations for verification. Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. The satellites carry very stable atomic clocks that are synchronized with one another and with the ground clocks.

Any drift from true time maintained on the ground is corrected daily. In the same manner, the satellite locations are known with great precision.

GPS receivers have clocks as well, but they are less stable and less precise.

GPS satellites continuously transmit data about their current time and position. A GPS receiver monitors multiple satellites and solves equations to determine the precise position of the receiver and its deviation from true time.

At a minimum, four satellites must be in view of the receiver for it to compute four unknown quantities three position coordinates and clock deviation from satellite time. More detailed description[ edit ] Each GPS satellite continually broadcasts a signal carrier wave with modulation that includes: A pseudorandom code sequence of ones and zeros that is known to the receiver.

By time-aligning a receiver-generated version and the receiver-measured version of the code, the time of arrival TOA of a defined point in the code sequence, called an epoch, can be found in the receiver clock time scale A message that includes the time of transmission TOT of the code epoch in GPS time scale and the satellite position at that time Conceptually, the receiver measures the TOAs according to its own clock of four satellite signals.

From the TOAs and the TOTs, the receiver forms four time of flight TOF values, which are given the speed of light approximately equivalent to receiver-satellite ranges. The receiver then computes its three-dimensional position and clock deviation from the four TOFs.

In practice the receiver position in three dimensional Cartesian coordinates with origin at the Earth's center and the offset of the receiver clock relative to the GPS time are computed simultaneously, using the navigation equations to process the TOFs.

The receiver's Earth-centered solution location is usually converted to latitudelongitude and height relative to an ellipsoidal Earth model. The height may then be further converted to height relative to the geoid e. These coordinates may be displayed, e.

User-satellite geometry[ edit ] Although usually not formed explicitly in the receiver processing, the conceptual time differences of arrival TDOAs define the measurement geometry.

The line connecting the two satellites involved and its extensions forms the axis of the hyperboloid.
