New Technology for Preventing Residential Electrical Fires: Arc-Fault Circuit Interrupters (AFCIs)




INTRODUCTION

Annually, over 40,000 fires are attributed to home electrical distribution systems.
These fires result in more than 300 deaths and over 1,400 injuries each year. Statistics
from 1992-1996 show level trends in each of these estimates with no indications of
decline. In 1996, $680 million in property loss was attributed to home electrical
distr ....etc

1.Zero voltage regulation in a transformer occurs at :
(A)zero p.f. lead 
(B)unity p.f.
(C )leading p.f.
(D)lagging p.f.

2.A parallel plate capacitor has 15 p.F capacitance. If the linear dimensions of the plate are doubled and the distance between the plates are also doubled, then new value of capacitance would be :
(A)15uF
(B)30 uF
(C )60 uF
(D)7.5 u.F

3.Resistance of a 230 V 100 W bulb is R1 and that of a 230 V 75 W is R2. Then,
(A)R1= R2
(B)R1 > R2
(C )R1 < R2
(D)R1 - 2R2

4.The current in a series ....etc

ABSTRACT



Because of high requirements in power, efficiency, installation space and weight, the design of electrical machines for hybrid electrical vehicles is a particular challenge. This seminar describes a comparative study allowing the selection of the most appropriate electric-propulsion system for a parallel hybrid electric vehicle (HEV). This seminar is based on an exhaustive review of the state of the art and on an effective comparison of the performances of the four main electric propulsion systems, namely the d ....etc
