A 1000V/400vV power transformer has a nominal short-circuit

M: +2.00/-0.66

A 1000V/400vV power transformer has a nominal short-circuit voltage V_SC = 40%. Which one of the following statements is correct?

[ESE (IES) EE 2017 (Technical)]

A A voltage of 400 V appears across the short-circuited secondary terminals.

B A voltage of 16 V appears across the short-circuited secondary terminals.

C When the secondary terminals are short- circuited, the rated current flows at the primary side at a primary voltage of 400 V.

D The primary voltage drops to 400 V, when the secondary terminals are short-circuited.
