Harmonic Problems in Power Transformers
Preventing malfunction in power transformers
BY ANDY SAGL, Megger
Harmonics are another power quality phenomenon that can cause equipment to malfunction. Harmonics are a sinusoidal component of periodic waves that have frequencies that are multiples of the fundamental frequency. Harmonics can cause computer equipment to lock up or cause the data to become garbled as well as causing transformers, motors, and neutral lines to overheat.
Linear loads such as incandescent lights draw current equally...
