A leak diameter for 1x10 -12 mbar*l/s (which equates to 1Å) is also the diameter of a helium molecule, which is the smallest detectable leak rate. (N.B. A leak rate of 1 mbar*l/s means a rise of 1 mbar from a 1 litre ... 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. cuddalore district news today
