In a power or distribution transformer about 10 percent end turns are heavily insulated to withstand the high voltage drop due to line surge produced by the shunting capacitance of the end turns.
Answer : The transformer laminations are insulated from each other by thin coat of varnish.
Answer : High voltage winding in a transformer has more number of turns.
Description : Increasing the number of turns of wire on the secondary of a transformer will (A) Decrease the secondary current (B) Increase the primary current (C) Have no effect on the secondary current (D) Increase the secondary current
Answer : Increasing the number of turns of wire on the secondary of a transformer will Decrease the secondary current
Answer : yes High Voltage side of Transformer winding have more number of turns. and low voltage side of Transformer winding have less number of turns.
Description : Write selection criteria of distribution transformer with any four points.
Answer : Selection Criteria for Distribution Transformer: i) Ratings - The kVA ratings should comply with IS:2026 ( Part l )-1977*. The noload secondary voltage should be 433 volts for transformers to be ... is not necessary. vi) Cooling - The transformers covered in this group are generally ONAN, AN
