Flux simulation on 100kVA three-phase transformer core
(Praise Worthy Prize S.r.l., 2010-06)
This paper describes the simulation of flux distribution on 100kVA 3 phase distribution transformer assembled with 60°-45° T-joint and mitred lap corner joint with stagger yoke and limb. The core that being used is 3% ...
Harmonic content as the indicator of transformer core saturation
(Institute of Electrical and Electronics Engineers (IEEE), 2010-06-23)
The paper proposes a measurement method for obtaining the parameters needed to calculate a reliable indicator of the state of transformer core saturation. The major nonlinear effects in transformer core are saturation, ...
A 5-level multilevel inverter using LM350 voltage regulator IC
(Institute of Electrical and Electronics Engineers (IEEE), 2010-06-23)
This paper presents a 5-level multilevel inverter for low power applications that not exceeding 30W using the common LM350 voltage regulator IC. A microcontroller with appropriate program is used to control on the biasing ...
A new proposal to solar and grid-connected hybrid electricity for homes and buildings in Malaysia
(Institute of Electrical and Electronics Engineers (IEEE), 2010-06-23)
This paper presents the proposal of a solar and grid-connected hybrid electricity system for homes and also buildings. A new concept of using a DC motor and synchronous generator as an electromechanical inverter is proposed ...
