What does S11-M-500/10 transformer mean?
Three-phase oil-immersed transformers, 11 series capacity of 500KVA, from 10KV variable 400V transformer
The first floor has been very accurate to answer my answer that M is sealed!
S represents three phases
11 design number
M indicates sealing
500 indicates that the transformer capacity is 500KVA
10 indicates that the rated voltage of the transformer high voltage side is 10KV
