Further development of standard voltage transformer:
EPRO´s R&D department realized a further development of the standard voltage transformer NVOS 30 to a new type named NVOS 30bc.
Compared to the NVOS 30 the NVOS 30bc works with dual core (bi-core) concept and has a smaller voltage error value and nearly a linear error curve over the whole voltage measuring range.
Please find attached a PDF with the test results of both types and a diagramm which shows the difference of the error curves.
The shown results are without adjustment by EPRO – so the voltage error can be kept in +-0,001%
At the moment only available for 1 voltage ratio, more ratios are in R&D progress.
