The hardware design of the high-pressure side of the circuit, and the choice of device specific instructions to do a given low-voltage side of the main signal processing flow chart. Made a Rogowski coil, and made a special design, gives the test wiring diagram. The results show that the coil made a good linearity and small measurement error, can be used for digital substation for current collection.
