Cable A
Cable A is a coaxial cable of constant cross section. The metal
regions are shaded in grey and are made of copper. The solid central
wire has radius a = 5mm, the outer tube inner radius b = 20mm and
thickness t = 5mm. The dielectric spacer is Teflon, of relative
permittivity &r = 2.1 and breakdown strength 350kV/cm. A potential
difference of 1kV is applied across the conductors, with centre
conductor positive and outer conductor earthed.
Before undertaking any COMSOL simulations we'll first perform some theoretical analysis
of Cable A based on the EN2076 lectures, to make sense of the simulations. Calculate the
radial electric field of cable A at radial positions r b. Also calculate the
maximum operating voltage of cable A, assuming a safety margin of ×2, and indicate where
on the cable's cross section dielectric breakdown is most likely to occur.
: For the gravity concrete dam shown in the figure, the following data are available:
The factor of safety against sliding (F.S sliding)=1.2
Unit weight of concrete (Yconc)=24 KN/m³
- Neglect( Wave pressure, silt pressure, ice force and earth quake force)
μ=0.65, (Ywater) = 9.81 KN/m³

I need help checking if its correct
-E1 + VR1 + VR4 – E2 + VR3 = 0 -------> Loop 1 (a)
R1(I1) + R4(I1 – I2) + R3(I1) = E1 + E2 ------> Loop 1 (b)
R1(I1) + R4(I1) - R4(I2) + R3(I1) = E1 + E2 ------> Loop 1 (c)
(R1 + R3 + R4) (I1) - R4(I2) = E1 + E2 ------> Loop 1 (d)
Now that we have loop 1 equation will procced on finding the equation of I2 current loop. However, a reminder that because we are going in a clockwise direction, it goes against the direction of the current. As such we will get an equation for the matrix that will be:
E2 – VR4 – VR2 + E3 = 0 ------> Loop 2 (a)
-R4(I2 – I1) -R2(I2) = -E2 – E3 ------> Loop 2 (b)
-R4(I2) + R4(I1) - R2(I2) = -E2 – E3 -----> Loop 2 (c)
R4(I1) – (R4 + R2)(I2) = -E2 – E3 -----> Loop 2 (d)
These two equations will be implemented to the matrix formula I = inv(A) * b
