Investigation of influence of voltage source type on harmonic characteristics
(Institute of Electrical and Electronics Engineers (IEEE), 2010-06-23)
This paper discussed about influence of voltage source types on harmonic characteristics. Usually, the voltage source is sinusoidal. But in actually, the condition of the load is has voltage sources through the elements ...
Testing of contactors under voltage sag and non-sinusoidal voltage conditions
(Institute of Electrical and Electronics Engineers (IEEE), 2010-11-29)
Sensitivity of electromagnetic contactors for voltage sags and non-sinusoidal voltage supply has been carried out by laboratory testing. Effects of sag characteristics such as; sag magnitude, sag duration and point on wave ...
