2.1.5 Define conductor properties<br />

Set the properties <strong>of</strong> conductors (layer1, layer2, gnd).<br />

The voltage on each layer must be calculated first.<br />

Electrical conductivity<br />

Unit: S/m<br />

Electrical resistivity ρ<br />

ρ is the static resistivity (measured in ohm-meters, Ω·m)<br />

E is the magnitude <strong>of</strong> the <strong>electric</strong> field (measured in volts per meter, V/m);<br />

J is the magnitude <strong>of</strong> the current density (measured in amperes per square meter, A/m²).<br />

Voltage on Layer 1 is the total voltage (130kV) from center <strong>of</strong> cable to the ground.<br />
