Leakage current can cause unnecessary downtime and intermittent RCD tripping of circuits, so quantifying it is an important part of a preventive maintenance programme. The new Fluke 368 FC and 369 FC Leakage Current Clamps, part of the Fluke Connect system of wireless test tools, help industrial electricians and maintenance technicians identify, document, record and compare leakage current readings to help prevent problems before they happen, without shutting down critical equipment.
The rugged meters have large diameter jaws (40mm for the 368 FC; 61mm for the 369 FC) for work with oversize conductors. The clamp jaws are fully shielded and designed to accurately capture very small leakage current signals (as low as 10mA) and minimise external electromagnetic interference. The true-rms meters are designed to accurately measure complex signals, with the highest resolution of 1µA and an upper measurement range of 60A.
Plasma technique converts landfill methane to jet fuel
Trevor; there are still many landfill sites in the UK where the methane is not captured but not only that, where there is protein waste in them, they...
