Grounding System Analysis in the Time Domain

INPUT DATA (in addition to XGSA_FD)

As for XGSA_FD and moreover:

• Maximum calculation frequency used 1, 10 or 100 MHz (1 MHz for switching transients, 10 MHz for lightning, 100 MHz for fast transients like fault transients in GIS)

• Parameters of the normalized transient function (Double Exponential, Pulse or Heidler functions)

• Number of critical frequencies (with default or customized selection)

OUTPUT RESULTS

XGSA_FD provides the time domain distribution and the frequency spectrum of the input transient (with linear and Log – Log scale plot).

XGSA_TD results are as for XGSA_FD but in the time domain.

Calculations of soil surface potentials, touch and step voltages, electric and magnetic fields are possible along lines.

XGSA_TD includes an option to export frequency dependent self and mutual impedances to EMTP® or ATP® in order to simulate with a rigorous model the dynamic behavior of large grounding systems during electromagnetic transients.

It is possible to represents:

• The time domain distribution of leakage current, longitudinal current, potential, electromotive force and complex power in each point on the electrodes with 1D representation
• The time domain distribution of soil surface potentials, touch and step voltages, electric and magnetic fields in each point of a line calculation
• The distribution of soil surface potentials, touch and step voltages, electric and magnetic fields along an entire line calculation at a fixed time
• The animation of the time domain distribution of soil surface potentials, touch and step voltages, electric and magnetic fields along an entire line calculation
