MR 270 C-A 微欧姆计

The MR270C-A is specially designed for electric resistance measurements in cable industry applications and inductive loads (transformers, motors). It is perfectly fit both for measuring the meter resistance in connection with a corresponding resistance measurement holding device or for final acceptance control of power cable reels. In the case of cable reels, which often have a cable length of several kilometers, both the compensation of the inductive component and the ability to perform measurements in the presence of high noise levels are important. This also applies to the winding resistance of transformers and motors

MR270C-A是专门为电缆工业应用和感应负载(变压器、电动机)的电阻测量而设计的。它既适用于与相应的电阻测量保持装置相连接的仪表电阻的测量,也适用于电力电缆卷筒的最终验收控制。在通常有几公里长的电缆卷筒中,感应元件的补偿和在高噪音情况下进行测量的能力都是很重要的。这也适用于变压器和电动机的绕组电阻。
