摘要: Output from a real-time sag, tension and ampacity program was compared with measurements collected on an outdoor test span. The site included laser range-finder, load cells weather station. A fiber optic distributed temperature sensing system routed along the conductor thermocouples were attached to conductor's surface. Nearly 40 million data points statistically computer output. provided results 95% confidence interval for temperatures within ±10°C sags ±0.3m of 75°C. Test also used determine accuracy IEEE Standard 738 models. transient model gave comparable up 160°C. Measured estimate radial axial gradients in ACSR conductor. effect insulators instrumentation local determined. rating is alternative installing measuring tension, sag or temperature. avoids problems maintaining expensive conductor, it will provide accurate information ground clearance real-time.
