Indian transformer will face two thing
1) heat
2) #Bushing ( a challenge to get and fit instrument to avoid transformer failure)
Your eyes only (BUSHING)
it will be not like that the bushing manufacture make more money then transformer company ( hahahahaha - deva re deva .....)
A transformer bushing is an insulating structure that facilitates the passage of an energized, current-carrying conductor through the grounded tank of the transformer.
Why do we use bushing in transformer?
In electric power, a bushing is a hollow electrical insulator that allows an electrical conductor to pass safely through a conducting barrier such as the case of a transformer or circuit breaker without making electrical contact with it
Classification and Construction
Electrical bushings can be broadly divided into two major categories depending upon how they are built and assembled:
#1 Bulk or Non-condenser Type
#2 Condenser Type
Design Requirements
The design of any type of electrical bushing takes into account the following requirements and aspects:
The central conductor of a bushing should be able to carry the anticipated load, or fault currents, without overheating the surrounding insulation (which can lead to abnormal loss of life).
For any given transformer, the conducting rod of a low voltage (LV) bushing is required to carry a higher current than its high voltage (HV) counterpart. Consequently, the conducting rod of a LV bushing is always thicker (has a larger diameter) than its HV counterpart.
A bushing’s internal insulation must be able to withstand the nominal operating and occasional transient electric field stresses placed upon it. These stresses arise due to the potential differences between the live conductor and grounded external surroundings. A bushing’s internal insulation should also limit the inception of partial discharges (PD), which can cause progressive deterioration of the insulation.
A bushing’s external insulation should provide sufficient dry arcing distance to withstand lightning strikes and switch impulses. The external insulation should also provide adequate creepage distance (leakage distance) to prevent excessive flow of leakage current; leakage current can result from a combination of pollution accumulation (dirt, sand, salt etc.) and/or ambient moisture
Do you have any idea what #TRIL at best ??
Its HOT here and pleasant
why you need to keep eye on SF6 - bushing ( nobody in this area AS BEST GE)
why kolavari D ?
What is SF6 used for? Around 80% of the SF6 used globally is in electricity transmission and distribution. Medium- and high-voltage electrical equipment contains SF6 to insulate the live electrical parts and to switch the flow of electrical current on and of
