Porous alumina ceramics were prepared through the space holder technique, using ground sunflower seed shells as a fugitive material and uniaxial pressing for forming the green ceramics. Influences of ...

Safety is always key. Charging a long cable run or motor with 1,000V or more can result in charges remaining in the equipment for a time after turning off the megohmmeter. It is the worker’s ...

Abstract: This article shows the interpretation of megohmmeter tests in electrical apparatus and circuits to ensure that insulation used in cables, motors, and switchgear is sound.

2. Insulation resistance testing. Some instruments have both the megohmmeter and insulation resistance testing functions. Test phase to phase and phase to ground with the contacts open. Use the ...

For example, an insulation resistance (IR) test is regularly performed on a winding using a megohmmeter, and the winding condition is assessed based on the megohm value obtained in the test; a stator ...

Any motor winding or electrical coil can be checked with a megger. A megohmmeter’s main function is to detect weak motor winding insulation and to detect moisture accumulation and acid formations from ...

This page has a bunch of electronics books in pdf format that the guy got by cutting up books and scanning them into Acrobat. I like these old textbooks because in the old days the people that wrote ...
