Abstract (en)
[origin: DE10237920B3] The method has the current measured at a potential which is relatively high compared to the earth potential as an analogue signal, which is converted into a digital signal fed to an evaluation device at earth potential. The analogue signal is subjected to compression prior to its A/D conversion and transmission, with subsequent expansion of the digital signal after transmission to the earth potential side. An Independent claim for a current measuring circuit is also included.
