摘要
各种电弧闪光方法的可用性，如IEEE 1584-2018和Ralph Lee方法，具有电压，电流和配置限制，因此在某些条件下，例如15kV以上的系统，不能很好地估计入射能量。电力研究所(Electric Power Research Institute)进行的试验证实了这一点[1]。利用这些试验数据，利用电压梯度和入射热通量的平均值，推导出简化的经验方程。这些方程为估计高压系统的入射能量提供了合适的工具。本文描述了这些方程，分析了不同输入参数产生的结果，并确定了结果模式，以帮助工程师最小化入射能量并提高人员的安全性。
Sensitivity Analysis of Epri Overhead Hv Line Arc Flash Model
The availability of various methods of arc flash such as IEEE 1584–2018 and Ralph Lee methods have voltage, current and configuration limitations and hence do not provide a good estimate of incident energy under some conditions such as systems above 15kV. This was confirmed for higher voltages from tests conducted by the Electric Power Research Institute [1]. With the experimental data available from these tests, empirical equations were derived in simplified forms by using the average values of voltage gradient and incident thermal energy flux. These equations provide a suitable tool in estimating incident energy in high voltage systems. This paper describes those equations, analyzes the results produced with different input parameters and identifies resultant patterns to help engineers minimize incident energy and improve safety of the personnel.
