摘要
结合工作实践探讨了在目标点天底无法到达时,高压输电线路的两种悬高测量方法,并对其测量原理、计算公式及测量误差进行了分析;指出在实际作业时的注意点。
Two methods of unsupported distance measurement were discussed when the target nadir could not be reached. The measurement principles, the calculation equations and the measurement error were analyzed. Some aspects which need pay special attention were also indicated.
