Type-A RCD failing 180 degree ramp test

Former Community Member

Hi


We are testing a type-A RCD (see image: "ABB") with a METREL MI 3152 (see image: "MI 3152 test").

As the image shows, the ramp test (I delta) is failing to trip the RCD for the negative half wave.


Have oneone seen this before?

    Is it actually doing a ramp test?




    Don't think so, I think is the RCD tripping time because in the image the results on the instrument are in milliseconds
