When the crank of a 500-volt megger is rotated faster than its designed rate, what maximum output voltage does it produce?
When the crank of a 500-volt megger is rotated faster than its designed rate, what maximum output voltage does it produce?
Right Answer is:
500 volts
SOLUTION
Now meggers are usually rated at 500 volts. To avoid excessive test voltages, most meggers are equipped with friction clutches. When the generator is cranked faster than its rated speed, the clutch slips, and the generator speed and output voltage are not permitted to exceed their rated values.
