This work is carried out to objectively establish a new method to detect
harmonics and measure the total harmonic distortion (THD) in a remote
source, such as a high voltage transformer. The proposed approach utilized
embedded design techniques to construct an embedded processor system
with Ethernet intellectual property core to acquire data from a remote
harmonics source. The designed system has several notable merits, namely,
it is portable that can be applied in the work field, and it avoids workers
from being subject to a hazard high voltage shock as well as its simplicity
and high accuracy. The harmonics detection and analysis are achieved by
inserting a microcontroller system near the high voltage transformer to
acquire the necessary data and transmit it to a remote embedded processor
system that is used to detect and analyze the harmonics. The microcontroller
and the processor systems are connected by a wide-area network (WAN)
through Ethernet and transmission control protocol/internet protocol
(TCP/IP) protocols. The processor system is accommodated to perform 128
points fast Fourier transform for harmonics detection. Matlab simulations are
used to validate the results. It is found that the results match very accurately
the simulation results with an error of less than 0.02%.
