What are K-factor rated transformers? K-factor rated transformers are capable of withstanding the heating effects caused by harmonic load currents. They are specially designed for non-linear harmonics generating loads. It is defined in the ANSI/IEEE C57.110 standard. Electronic circuits, switched-mode power supplies and semiconductor switches draw a large amount of non-linear current causing distorted current. … Read more
A certain amount of current is drawn by a transformer from the source connected to it primary even when no load is connected to its secondary. A part of this current is used to create flux in the transformer core. This current is known as magnetization current. Definition of magnetization current Magnetization current can be … Read more
Transformer inrush current or magnetization inrush current is a transient input current drawn by a transformer during its energization. Depending on several factors, the magnitude of the magnetization inrush current can be somewhere from 5 to 30 time the rated full load current of the transformer. This happens even when the transformer is energized at … Read more
CFL lamps or compact fluorescent lights are made to make lighting more energy efficient. It started replacing the incandescent lights. It was invented by Edward Hammer in1980 who was an Engineer at GE. The power consumption of CFL ranges from 10 watts to 50 watts depending on its extraction rate. Enter the wattage, hours of … Read more
