Abstract :
The 3A motor primary fan is one of the most important engines in a power plant because of its role in the process of increasing combustion in a furnace to produce steam. Needs to be removed. Interference with the primary fan motor 3A can cause a short circuit fault current. The disturbance occurs on the motor, of course, will experience damage when decreased. While the results of the three phase short circuit current that will occur are determined under three different conditions. The first condition = 9486.09 A, the second condition = 5573.96 A and the third condition = 8155.64 A. Protection of the motor is very crucial in the discussion of the funding system so that the necessary protection settings are needed Damage to the motor. In the event of a short-circuit current problem protection is needed for high-current and low-level current relays. While the settings are set for the motor at value, high level = 8.02 A and low level = 4.00 A.
