The MLS 7100 transformer loss measuring bridge was especially designed to greatly simplify the determination of transformer core and copper losses – an ideal choice when working on site. The measuring bridge features open circuit as well as short circuit measuring. Many transformers can be directly connected to the
MLS 7100 without needing further transducers.
MLS 7100变压器损耗测量电桥的设计，大大简化了变压器铁芯和铜损耗的测定，是现场工作的理想选择。该测量桥具有开路和短路测量功能。许多变压器可以直接连接到MLS 7100，而不需要进一步的换能器。
