MR 8050 高感应电阻计

for highly inductive Test Objects up to 800 MVA

With the MR 8050 resistances highly inductive Resistance Meters windings of transformers, motors and reactors can be measured. (range 100 µΩ with 0.01µΩ resolution up to 6 kΩ).

The performance of the test objects can be up to 800 MVA or even more. The magnetic loading of a transformer is performed quickly using a high loading voltage (60V). This is important for time critical measurements (cooling curves). The unloading of the transformers core is very fast, very safe, as the energy is total destroyed in the MR 8050.

对于具有MR 8050电阻的高电感测试对象,可测量变压器、电机和电抗器的高电感电阻计绕组(范围为100Ω,分辨率为0.01 mVA,Ω分辨率可达6kΩ),测试对象的性能可达800 mVA或更高。利用高负载电压(60V)快速执行变压器的磁负载。这对于时间临界测量(冷却曲线)很重要。变压器铁芯的卸载非常迅速,非常安全,因为能量在8050先生中被完全破坏。
