1.Main transformer
Sonadih2nd clinker line Project
•
Main transformer should be always out door type.
•
Lafarge mandatory safety requirements for main transformer are to be followed.
•
Main transformer to be mounted on at least 90 lb rails. (Refer animation for the typical arrangement)
•
Main transformer & the switch yard to be protected by a fence of at least 2.5 mtr height & the fence to be grounded at least two points.
•
Main transformer neutral to be grounded separately with a separate color – Switch yard general earthing – Green color.Transformer neutral earthing – Black color.

1.Main transformer- oil soak pit requirements
Courtesy – IE rules – 1956 Rev 2000 •
The location of the oil soak pit should be out side the switch yard
•
The capacity of the soak pit should be suitable for the entire oil capacity of the live transformer

2.Switchyard towers & gantries
•
Switchyard structures should be of bolted structures and should be of GI angular structures/ pipe structures.
•
Switchyard structures should be low bay type.
•
IPS aluminium tubular conductor type switchyard is preferred.
•
Switchyard equipment creepage distances should be at least class-3 of IEC 34.
•
The lightning arresters should be with min discharge current of 10 kA and should be metal oxide and gapless type.
•
Each bay is to be supported by a breaker, Isolator with earth switch , set of CT,set of lightning arresters PT may be based on the requirement.
