    I have a question I'd like to submit.
    I'm trying to achieve a measure of differential current.
    I'm using a CR8348-2000 in which I inserted into the hole in both phases (phase and neutral). As the load resistance across the CR will use a 90.9k, then enter a LTC1967 and from there into a PIC. The scheme is in fact the one in the LTC1967 data sheet (http://cds.linear.com/docs/en/datas...1967f.pdf) on page 26.
    The problem is the response time.
    thanks for your cooperation and sorry for the bad English

    Dear Sir,

    Your application requires the use of a ground fault current transformer. I have attached the catalog page for our CR8400 Series. We cna have pins placed on these instead of wire leads if necessary.
