WebMegger Insulation Tester - Instrumart WebA gap exists where the jaw tips of a Hall Effect clamp meter meet, creating an air pocket that the magnetic field (aka magnetic flux) must jump. This gap limits the magnetic flux so that the core cannot saturate. In contrast, the jaws of an ac-only current transformer clamp are flush when closed.
