(OP)
Hello friends,
Does the type of transformers ( Knan, onan etc) one can use matter depending on whether they will be placed inside or outside a substation ? could someone explain what the rule is on this.
thank you !

A KNAN transformer with a high fire point liquid is one solution where a transformer failure and fire is a concern.
RE: transformer type
Now a days, these are not preferred and instead, we have natural ester or vegetable based fire resistant liquids available.
Silicone liquids or synthetic and have limited biodegradability and thus are not preferred environmentally.
Mineral oils that are widely used in transformers are not suitable for indoor use due to the low flash point and also because the fire can sustain once started.
'O' in ONAN refers to mineral oil and 'K' in KNAN refers to liquids with >300degC flash point (and thus suitable for indoor use).
