Harmonic Distortion Calculator helps contractors and tradespeople accurately size, spec, and estimate materials and systems.
Formula
THD = √(V₂² + V₃² + ...) / V₁ × 100
Guida passo passo
- 1Measure fundamental and harmonic voltages with power quality meter
- 2Apply the formula using your project measurements
- 3Add required safety factors or waste allowances per code
Esempi risolti
Ingresso
V1=120V, V3=6V, V5=4V
Risultato
THD = √(36+16)/120 × 100 = 6.0%
Errori comuni da evitare
- ✕Not applying code-required safety factors or derating
- ✕Forgetting to account for waste and cut losses in material estimates
