Introduction The 368/369 AC Leakage Current Clamp (the Product) is a handheld tool for measurement of ac leakage current. Principle of Leakage Current Measurement Based on the electromagnetic induction principle, the Product has a ring-shape current transformer comprised of a metal core and coil winding. The current transformer senses the magnetic field produced by the current or by the vector sum of the currents flowing in the conductor under test.
