HOW THIS VERIFICATION WORKS

  1. Step 1: Size battery capacity accounting for Peukert loss and thermal derating — engineering workflow step. Follow the documented method for manual execution.
  2. Step 2: Compute statistically robust STA/LTA threshold for target false alarm rate — engineering workflow step. Follow the documented method for manual execution.
  3. Step 3: Determine grounding resistance limit for surge voltage compliance — engineering workflow step. Follow the documented method for manual execution.

This tool coordinates 0 validation steps and 3 calculation steps. The overall engineering decision uses ALL_REQUIRED_VALIDATION_PASS aggregation: only validation steps contribute to the pass/fail outcome; calculation steps produce data only.

METHODS & EQUATIONS

All formulas are resolved from canonical runtime definitions and executed deterministically by the client-side engine.

Step 1: Size battery capacity accounting for Peukert loss and thermal derating

Manual Workflow
C_bat = [Total energy demand (J)] / V_sys / Depth-of-Discharge factor / Temperature derating factor; where DoD factor = 0.85 (85% usable), and thermal derating = 0.92 + 0.002*(25−T_min) per IEC 62619 Annex D for LiFePO₄.

Step 2: Compute statistically robust STA/LTA threshold for target false alarm rate

Manual Workflow
Use extreme-value distribution of STA/LTA statistic under Gaussian noise: ρ_th = sqrt(2) * erfcinv(λ_ft / (f_s * T_lta)) * sqrt(T_lta / T_sta); where erfcinv is inverse complementary error function. Valid for T_lta ≫ T_sta and high-SNR approximation.

Step 3: Determine grounding resistance limit for surge voltage compliance

Manual Workflow
R_g,max = (V_gpr,max / I_pk) × (1 + 0.02·√(ρ_s/d)), incorporating empirical ionization enhancement factor for 8/20 μs impulses per IEEE Std 142 (Green Book) Annex C.

UNDERSTANDING THE RESULTS

PASS
A proven validation criterion passed. The engineering input satisfies the deterministic threshold.
FAIL
A proven validation criterion failed. The engineering input does not satisfy the deterministic threshold.
CALCULATED
A deterministic calculation completed, but no acceptance criterion exists for this step. CALCULATED does NOT mean PASS.
RESULT NOT VALID
Runtime executed but engineering validity requirements were not met.
INCOMPLETE
Required inputs or workflow steps are incomplete.

The overall decision reflects only validation steps. Calculation steps produce numerical results without pass/fail claims.

WHEN TO USE THIS TOOL

  • When deterministic Borehole Seismograph engineering verification is needed for project-specific conditions.
  • For calculation of Size battery capacity accounting for Peukert loss and thermal derating (Step 1).
  • For calculation of Compute statistically robust STA/LTA threshold for target false alarm rate (Step 2).
  • For calculation of Determine grounding resistance limit for surge voltage compliance (Step 3).
  • For deterministic pre-checks before formal engineering review or submission.

When NOT to use this tool: This tool does not replace laboratory testing, formal engineering analysis by a licensed professional, or code-compliance certification. It performs deterministic threshold comparison and calculation only.
