Why power factor of the transformer under no load is very low?

How does an under-voltage load shedding scheme work?
Answer : An under-voltage load shedding scheme is a protective mechanism used in electrical power systems to prevent damage and ensure the stability of the grid when the voltage drops below a certain threshold ... voltage drops below safe levels, allowing the system to recover and avoid more severe issues....
