Question { 3230 }

Im designing APFCR Panel for 600 KVAR.I need to calculate
the full current so that i can choose the capacity of
isolator/Breaker.Kindly suggest with formula.


Answer

600 kvar/kv x 1.73 So if the voltage = 400 volts the
amperage = 600/0.40 x 1.73 = 867 amps. Your breaker would
be determined by your local code. USA would be
867 x 1.35 = 1170 or a 1200 amp breaker.

Question { Power Grid, 9138 }

what is the physical phenomenon because of which skin
effect occurs ??


Answer

Skin effect is the tendency of an alternating electric
current (AC) to become distributed within a conductor such
that the current density is largest near the surface of the
conductor, and decreases with greater depths in the
conductor. The electric current flows mainly at the "skin"
of the conductor, between the outer surface and a level
called the skin depth. The skin effect causes the effective
resistance of the conductor to increase at higher
frequencies where the skin depth is smaller, thus reducing
the effective cross-section of the conductor. The skin
effect is due to opposing eddy currents induced by the
changing magnetic field resulting from the alternating
current

Question { CTS, 19826 }

find the remainder when 2222^(5555)+5555^(2222)is divided
by 7


Answer

Sol: the remainder of a^c + b^d when it is divided by x is
same as the sums of rems of a,b to the power c and d.
2222/7 has a remainder of 3 and 5555/7 has a remainder of 4.
So (3)^5555 mod 7 + (4)^2222 mod 7 is the same as
(3)^5 mod 7 + (4)^2 mod 7 = (5 + 2)mod 7 = 0
