Normal power supply in Port Moresby was restored on Easter Saturday after the fault was identified on late Friday afternoon.
The fault was located between Kanudi and Moitaka after a line patrol was conducted.
It was found that there was a conductor causing the short circuiting when PPL was trying to restore power supply during the four days of load shedding.
The fault was isolated and could not pick up on the PPL system control and was only located when linesmen conducted a patrol of all transmission lines between Kanudi and Moitaka.
Customers still experiencing power outages are encouraged to call the National Call Centre on 7090 8000 or 7653 5261.
