Fluke has launched the Fluke 368 & 369 true-RMS leakage current clamp meters that help users detect, document, record and compare leakage current readings over time as a means of preventing unplanned downtime, and identifying intermittent GFCI (ground fault circuit interrupter) and RCD (residual current device) trips, all without taking equipment off line.
The Fluke 368 has a large (40 mm diameter) jaw for work with big conductors. The clamp’s jaw is fully shielded to capture very small leakage signals, and to minimise external electromagnetic interference. The device allows users to track changes in leakage current over time, helping to identify potential problems before they turn into major failures. Other features include:
• True-RMS measurements for accuracy when measuring complex, non-sinusoidal waveforms.
• Highest resolution of 1 A, measure up to 60 A
• Selectable filter function removes unwanted noise.
• Max/min/average readings and hold function.
• Forward-facing LED work light for use in dark wiring cabinets.
• Backlit display, auto backlight off and auto power off for extended battery life.
• CAT III 600 V safety rating.
• Internal memory logging: up to 65 000 measurement points.
Designed specifically for industrial electricians and facilities maintenance technicians, the 368 and 369 are invaluable for general purpose electrical maintenance, as well as preventative and predictive maintenance and fault troubleshooting. Specific applications include maintenance tests on motors and transformers, and current leakage measurements for installation tests.
Unpacking the technoeconomic case for cleaner power in wastewater plants Schneider Electric South Africa
Electrical Power & Protection
Behind every reliable wastewater plant is an electrical system exposed to the effects of harmonics, voltage distortion and overloaded networks caused by fleets of variable speed drives on pumps and aerators.Together, they steadily drive up maintenance demands and elevate the risk of failure.
