摘要：<p>PURPOSE:To enable accurate simulation of the process of formation of a snow tube or drop of snow in simulated manner by a method wherein the state of snow coating on an overhead transmission line being rotated by the snow coating is simulated by using a short wire sample. CONSTITUTION:A wire sample 1 is much shorter than a span length of a transmission line to be simulated. Even when the same snow coating as at the central position of a span, for instance, is given to the sample 1, therefore, only a much smaller rotational angle than an actual one is given to the sample 1 by the moment alone given by said snow coating. However, a torque by the moment is detected by a torque sensor 3, a rotational angle to the same torque as the above at a prescribed position of a prescribed transmission line, which is stored beforehand in a memory 10, is accessed by CPU 7, the value thereof is used as the number of pulses, and a pulse motor 4 is rotated to said rotational angle. The wire sample rotated thereby is put in the same state of rotation as with the one caused when the same amount of snow with that sticking to the sample is given to the prescribed position of the prescribed actual transmission line.</p>
