Length L (m) *

Width W (m) *

Height H (m) *

Location Factor Cd (Environmental Surroundings)

Soil Type & Resistivity

Predominant Soil at Electrode Depth

Marshy / wet organic soil

Resistivity Range: 5–50 Ω·m · Corrosion Risk: Low–Moderate

Excellent conductivity. Watch for organic-acid corrosion on ferrous electrodes.

Climate Zone Classification

Regional Climate Zone

Tropical monsoon (high rainfall)

Dry-season Multiplier: ×0.7 · Corrosion: Moderate

Resistivity drops in the monsoon and rises markedly in the dry season — audit both seasons.

Lightning Ground Flash Density (Ng) & LPS Class

Enter Ng directlyDerive from Thunderstorm Days (Td)

Ng — Flashes / km² / year *

Existing Lightning Protection System (LPS) Class

Typical Ng values in India: Inland temperate 1–4, humid subtropical 4–8, tropical monsoon / coastal 8–14+.
