Yerga ulash o'tkazgichi qarshiligi qanday hisoblanadi?

For a single vertical rod: R = ρ/(2πL) × ln(4L/d), where ρ is soil resistivity (Ω·m), L is rod length (m), and d is rod diameter (m). This formula assumes a uniform soil model.

Yerga ulash qarshiligining qabul qilinadigan qiymati qancha?

Odatiy me'yorlar: <5 application.

Parallel o'tkazgichlar qarshilikni qanday kamaytiradi?

Parallel rods reduce total resistance, but not proportionally due to mutual interference. For N rods spaced at distance s: R_total ≈ R_single/N × (1 + interaction factor). Rods should be spaced at least 2× rod length apart for best efficiency.

Tuproq qarshiligining odatiy qiymatlari qanday?

Wet clay: 10-100 Ω·m. Loam/garden soil: 50-200 Ω·m. Sand: 200-3000 Ω·m. Gravel: 3000-10000 Ω·m. Rock: 10000+ Ω·m. Soil resistivity varies greatly with moisture, temperature, and mineral content.

Tuproq qarshiligini qanday o'lchash mumkin?

Wenner to'rt-zond usuli eng keng tarqalgan: yerga kiritilgan to'rtta teng masofali zond ishlatiladi. Tok tashqi zondlar orqali o'tkaziladi, kuchlanish esa ichki zondlar bo'ylab o'lchanadi. ρ = 2πaR, bu yerda a — zondlar orasidagi masofa, R — o'lchangan qarshilik.
