WebLeakage Current Measurement. Leakage current is the current that streams from either DC or AC circuit in an electrical system to the frame, or to the earth or ground, and can be either from the output or input. The current will stream through other pathways such as the human body, if the equipment is not properly earthed. WebCheck the Ground Conductor to Measure Leakage Current This is another easy way to measure leakage current. Use the clamp meter and put the clamps around the ground conductor. Make sure that you have the desired ground connection. Check out the leakage flow and see if it’s in an acceptable range.
