Can the EVALSTPM-3PHISO board support Rogowski coils?

Hi there.

I have been asked to look at your eval board, EVALSTPM-3PHISO. The question is, i want to use Rogowski coils, can this board accept them or do i need another product.

Many thanks

The EVALSTPM-3PHISO is designed for current transformers. A Rogowski coil cannot normally be connected directly to its current inputs.

Rogowski coils produce an output proportional to di/dt. They therefore require an integrator to convert the signal into a voltage proportional to current.

Thank you for the reply. It confirms what i was thinking. I will use the reference design and alter it to interpret the di/dt signal.

Many thanks
