| Summary: | This project is the starting point for detail research in the harmonics effect on
electromechanical overcurrent relay. The main purpose of this project are to study about
the harmonics current effect on the Miniature Circuit Breaker (MCB) and to characterized
the harmonics current versus MCB tripping characteristic. Nowadays, most of the MCB
set on the fundamental current and neglected the harmonics current that exist in normal
distribution system. In addition, there is always the problem faced by the consumer where
the MCB tripping occurred before the rated current value because that is taken by using
common brand of clamp meter. In this project, experiment was conducted on the MCB
which was injected with harmonics rich current by programmable AC source. Two types
of clamp meter, common brand and good brand were used to measure the current from the
experimental. Then, the new tripping characteristic of the MCB which included harmonics
current will be characterized. It will be compared to original tripping characteristic
(without harmonic) and new tripping characteristic (with harmonic). |
