Harmonic Distortion Calculator helps contractors and tradespeople accurately size, spec, and estimate materials and systems.
ସୂତ୍ର
THD = √(V₂² + V₃² + ...) / V₁ × 100
ଷ୍ଟେପ୍-ଷ୍ଟେପ୍ ଗାଇଡ୍ |
- 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
ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ
ଇନପୁଟ୍
V1=120V, V3=6V, V5=4V
ଫଳ
THD = √(36+16)/120 × 100 = 6.0%
ଏଡ଼ାଇବା ଯୋଗ୍ୟ ସାଧାରଣ ଭୁଲ
- ✕Not applying code-required safety factors or derating
- ✕Forgetting to account for waste and cut losses in material estimates
