Fluke 360 leakage current meter fluke fluke 360 leakage currents can be an indicator of the effectiveness of insulation on conductors high levels of leakage current may be present in circuits where either the insulation resistance is low or electronic equipment with filters is used leakage currents can cause disruptions of the normal operation of equipment and installations it is possible to locate the source of leakage currents by using the fluke 360 leakage current clamp meter and takin
