The aim of this study is to propose simple and reliable techniques to assess the condition of metal oxide arrester based on the dielectric response techniques. A number of modern electrical diagnostics for Metal Oxide Surge Arrester (MOSA) are discussed in this paper. The techniques included return voltage, decay voltage and polarisation/depolarisation current measurement. The single and multipulse current (8/20micros) was used to artificially degrade the MOSA. The before and after diagnostic ....etc

Electrical Drives of Machine Tools
Introduction
The arrangement of the motor nearby the operative member and also the use of variable-speed electric motors make it possible to simplify mechanical transmissions as well as the construction of the machine.
This helps to improve machine-tool design and considerably reduce the physical force required to handle the machine.
Introduction
One or more electric motors driving the operative members of the machine tool make up the machine's essential components.
