Manas P

Hello All,

We are looking for Active Integrator module for Rogowski coil to measure the current/voltage surges for the specifications mentioned below.

 

  1. 8/20uS (micro seconds) impulse current of Peak Magnitude 250kA
  2. 10/350uS (micro seconds) impulse current of Peak Magnitude 250kA

 

I found one design from TI in the below mentioned link. But im couldnt find any Application note of design criteria for the selection of the Integrator for the Rogowski Coil for the above mentioned Impulse Surges.
