why should we use pulse transformer rather than ordinary transformer
What is the definition of earthing and how it works?
An earthing transformer provides a neutral in a delta connected system.
Earthing of a transformer is done to 1:reduce the sensitivity of protective relays. 2:reduce the damage due to fault current. 3:get rid of great loss of equipment and money in case of any earth fault.
An isolation transformer is a mutual transformer having a voltage ratio of 1:1, so that the secondary circuit is electrically isolated from the primary circuit, yet subject to the same voltage.An earth protection relay is a category of protective relay that responds to an earth fault monitored by a current transformer (CT). In the event of an earth fault being detected by the CT, the relay with activate the trip circuit to a circuit breaker which will then disconnect the fault.
1. USE GROUNDING TRANSFORMER OR ZIGZAG TRANSFORMER 2. USE SOIL CONDITIONING AGENTS - MARCONITE CONDUCTIVE AGGREGATE AND BENTONITE MOISTURE RETAINING CLAY ON EARTH ELECTRODE BACKFILL.
Well there's the Decepticons who are bad guys, the use for them is the destruction of Earth, and the Autobots they are the good guys, the use for them is to stop the Decepticons from obliterating Earth.
Frgi transformer
yes we can place auto transformer in place of original transformer
5
To ascertain the life of insulation, or effectiveness of the insulation (HV to LV, HV to earth and LV to earth) of the transformer
Ideal transformer is useful in understanding the practical transformer..i does't have losses...
why should we use pulse transformer rather than ordinary transformer
In 1600 kva transformer we provide NGR (Neutral grounding resistance)
When power is generated by the power company they use the earth as one of its wires. They use earth because the earth is a great conductor, therefore the end user can use this "wire" as another leg to their system. You can also do this with a delta transformer.
yes it will have a local power uses then we can use it with separate earth pits and else cases i.e. if you are transforming power throgh Step up transformer then separete grounding transformer is required for NG. hope the above will clezar the doubts Regards K. Vithal
we cannot use transformer because transformer cannot change frequency . . .
