Partial discharge monitoring is an effective on-line predictive maintenance test for motors and generators, as well as other electrical distribution equipment. The benefits of on-line testing allow for equipment analysis and diagnostics during normal production. Corrective actions can be planned and implemented, resulting in reduced unscheduled downtime. This paper will present a theory to prom...

For three-phase six-electrode submerged-arc furnaces, a technical solution has been proposed that allows to determine the contour of an electrode with arc discharge by analyzing harmonic spectrum offset voltage zero point, created artificially. Researches carried out on industrial furnace which melts ferronickel, have confirmed possibility using method for monitoring and controlling operating m...

The creation of modified layer on metal surfaces using new methods is one of the procedures in surface engineering which can improve the surface mechanical properties. The electrical discharge process is a new method that can form a modified layer on the metal surfaces. This study aims to improve of pure aluminum surface properties through Electrical Discharge process with Monel 400 electrode. ...

Many studies employing various methods have been carried out into the number densities of excited atoms in electrical discharges with inert gases [1,2,3], but the ranges of the discharge current and gas pressure is very limited in them all. In this work, the population densities of 3S, 3s' of neon have been investigated using the atomic absorption method. Since the discharge current and gas...

In this study, the Electric Spark Discharge Method (ESDM) was employed with micro-electrical discharge machining (m-EDM) to create an electric arc that melted two electrodes in deionized water (DW) and fabricated nano-Au colloids through pulse discharges with a controlled on-off duration (TON-TOFF) and a total fabrication time of 1 min. A total of six on-off settings were tested under normal ex...

The aim of this study is the presentation results an in-lab comparative electrical and thermal monitoring artificially polluted, HTV-textured silicone rubber insulators, with different pollution levels. This work a preliminary in-situ 400 kV SiR textured in polluted environment. showed that rms leakage current magnitude pulses, average dissipated power depended on levels dry-bands formation. di...
