伏安法测量地阻有明显的不足之处,试验时,接地棒距离地极为20～50m,而辅助接地距离接地点40～100m。另外，受外界干扰影响极大,在强电压区域内有时无法测量。测量仪检测法。单钳口接地电阻测试仪是当前较为热门的一种地阻测试仪。由于仪器体积小巧,操作又十分简便,不失为检测接地装置好坏的仪器。该仪器适用于输出电线杆塔、微波塔、避雷针等接地装置的接地电阻测量。单钳口接地电阻测试仪在测试时虽然使用一定频率的信号以排除干扰,但在被测线缆上有很大电流存在的情况下,测量也会受到干扰,导致结果不准确,且无法测量土壤电阻率。

LED灯具作为节能项目的重要手段，正得到越来越广泛的应用。而大型LED灯具同样有相对较大的发热量，散热结构的好坏影响着LED灯具的质量及寿命，红外热像仪通过检测LED灯具散热器表面的温度分布，帮助工程师改善散热设计，提高LED灯具的产品质量及寿命。为什么要对LED灯具进行散热由于LED的功率在不断提高，及空间具有一定局限性，LED灯具散热成了比较突出的问题，需要开发更加*的散热器才能在今后满足LED灯具对于散热的更高需求。
