Calculated physical quantities in Transient electric

Help contents

The QuickField postprocessor calculates the following set of local and integral physical quantities at any given moment of time or as time-dependent graphs and tables:

Local quantities:

• Electric potential U;
• Electric field intensity vector E = –gradU

  Planar case: \[ E_x = -\frac{\partial U}{\partial x}, \quad E_y = -\frac{\partial U}{\partial y} \]

  Axisymmetric case: \[ E_z = -\frac{\partial U}{\partial z}, \quad E_r = -\frac{\partial U}{\partial r} \]

• Vector of active j = σ·E, and reactive j_d = ∂(ε·E)/∂t current density;
• Active power (losses) density:  Q = j·E.
• Electric permittivity ε(E);
• Electric conductivity σ(E).
