Answer / surya

basically AVR i.e. Automatic Voltage Regualator is used to
Control the output of the generator.

Answer / bala

AVR - Maintain the output voltage according to the set
value and Governor - Maintain the output Frequency(speed)
according to the set value.

Answer / pillay

What control are you talking about?As Suria and Bala has said
AVR controls the voltage and governor controls the speed.If power
output is the concern than you may have to say the over current
protections and if the fault current is of concern than earth
fault relays like wise there are so many devices to control the
generator output.

Draw an S.L.D of the main panel for a hospital, showing meter position. Essential loads are: 1) Equipment load 100 KW 2) Critical load 500 KW 3) Life AID Safety load 400 KW 4) NON-Essential load 200 KW 5) Other service loads 200 KW Calculate and suggest the size of the transformer, size of main cable, capacitor bank, and calculate the capacity of an emergency load having above first three mentioned loads is supplied by an emergency generator.
