STUDY ON CHARACTERISTICS OF TRIPLEN HARMONICS PRODUCED BY SYNCHRONOUS GENERA TOR FLOWING THROUGH TRANSFORMER UNDER VARIOUS LOAD CONDITIONS

The existence of triplen hrumonics in equipments has been recognized dated back in the 19th
century. Even though many discovery has been made regarding the behaviour of triplen
hrumonics in electrical equipments, many scope still needed to be studied and researched. Thus,
the objective of this paper focuses on the characteristics of triplen hrumonics produced by
synchronous generator flowing through various transformer winding configurations subjected to
variety of load conditions. The scope of experiment for this study covers on the laboratory
experiments using lab-scaled salient pole synchronous generator that connects directly to the
transformer and load. The transformer has four winding configurations and the load can varies in
different resistance and inductance connections in a circuit. The study also covers the PSCAD
modeling software. The results obtained from PSCAD modeling can be analyzed and also
compare with the laboratory experiments that have been conducted. The results and findings
from the lab experiments and PSCAD modeling are to be discussed and thus, able to come up
with an appropriate conclusion in the characteristics of triplen hrumonics produced by
synchronous generator flowing through various transformer winding configurations under
various load conditions. In conclusion, this study provides a very important know ledge of trip len
hrumonics current propagation through transformer.
