When manufacturers perform ratio and winding resistance tests at the end of the production process or during factory acceptance testing, time is costly and performing such tests efficiently is crucial. When performing diagnostic tests on site, there's also a limited window of time. The CPC 100 and the CP SB1 switchbox make ratio and winding resistance measurements efficient by avoiding climbing up and down the transformer repeatedly and reducing connection errors.
