In Genrator - Excitation Ceiling voltage is the maximum
Voltage that may be attained by an elicitor with specified
condition of load.
Rated load field voltage is the required voltage across the
terminals of the field winding for rated load and rated
voltage

Answer / narayanan

ceiling current is nothing but the maximum dc current which
can be given to the field winding of the syn.generator fox
its excitation

Answer / raul

ceiling voltage is d maximum voltage that can be applied
across d field winding of a synchronous generator upto d
point of unstability.
In a static excitation system, the rectifier transformer
performs this function of supplying d ceiling currents at d
rated ceiling voltage for a short period of 10 seconds. and
it is usually done to avoid d system going into unstability.
