Short Answer: Dew point measurement is necessary to ensure the moisture content of the cellulose insulation is low enough to safely energize the transformer (after filling with oil). Maximum acceptable moisture content varies with unit size/age, but less than 1% moisture content is generally acceptable.

Why is nitrogen used in crisp packets?
Nitrogen is used in crisp packets due to its inert properties, which help maintain the freshness and crispiness of the chips. By replacing oxygen with nitrogen, the oxidation process that degrades the chips is slowed down, allowing them to stay fresh for longer periods.
What happens when water vapor is lighter than nitrogen or oxygen?
Water vapor is a gas so it is in the air. Nitrogen and nitrogen are in the air too, but there is more nitrogen than anything in the air. I believe it rises because it is lighter, like a balloon filled with helium.
What is the neutral atom that has its first two energy levels filled has 5 electrons in its third energy level and has no other electrons?
This atom is nitrogen with an atomic number of 7. The first two energy levels (K and L) are filled with 2 and 5 electrons, respectively. The third energy level (M) has 5 electrons, giving a total of 12 electrons for the neutral nitrogen atom.
How many valence electrons does a nitrogen N atom have?
The atomic number for nitrogen is 7. Neutral nitrogen must have both 7 electrons and 7 protons then. The first 7 orbitals are filled as 1s2 2s2 2p3, which shows us that nitrogen has 5 valence electrons.
Why nitrogen is diamagnetic while contains unpaired electrons?
If you are going by the electron configuration of nitrogen then the unpaired electrons in the 2p shell would indicate that it is paramagnetic. However experiments show that it is diamagnetic. You must remember that nitrogen is a diatomic element and as such is found as N2. The molecular orbital theory explains how there are no unpaired electrons in the bonds between the two N atoms. The 1s and 2s molecular orbitals are completely filled and all of the bonding 2p orbitals are also filled. There are no electrons in the any of the 2p anti-bonding orbitals. Seeing a molecular orbital diagram for N2 will clarify what i mean.
Is there need of transformer oil in all transformers?
No not really only some do :DAnswerFor transformers used in transmission and distribution systems, yes. Transformer oil is necessary for cooling and insulation purposes, enabling the 'footprint' of an oil-filled transformer to be smaller, and its rating to be higher, compared with those not filled with oil.
Oil filled transformer is usually used indoor or outdoor?
An oil filled transformer is usually used outdoors and a dry core transformer is usually used indoors.
Can i Over load an oil filled transformer?
Any transformer can be overloaded by applying a load above the capacity rating of the transformer.
What is filled in airplane tires?
Nitrogen is filled in aeroplane tyres.
What is the specified value of dew point of nitrogen filled in transformer?
always see that the addition of insulation temprature ( ambient temprature or atmospheric temprature) and dew-point value (in minus) (ignore the minus) should be equal to 60 ok if the additon is qual to 60 then the dew-point value is ok if more than 60 and less than 65 then the value is also ok but not should br less than 59.
What is life expectancy of oil filled transformer?
6 years
Are BMW tires filled with Nitrogen?
No.
What is the Cost of SF6 gas insulated Transformer?
2-3 times more than the cost of a mineral oil filled transformer.
What gas will be filled in aeroplane wheels?
Nitrogen
Is a hot air balloon filled with nitrogen?
It is filled with heated air. Since air is mostly nitrogen, a hot air balloon is mostly filled with nitrogen.
Name of transformer oil?
An oil transformer is filled with PCB oil to better transfer heat from the windings to the outside case (and into the air).
What orbital is filled when nitrogen becomes an ion?
2p
