In a 11000/440 V transformer, when any one phase of 11 KV
supply fails (ie., single phasing), what happens to the
secondary voltage and why?
Answer Posted / haiderali
When any one phase of 11 KV supply fails, phase voltage
will be half of the normal voltage in two phases of
secondary side while only one phase will deliver full
voltage (i.e. 440/sq.root3)with respect to neutral.
