Study on Monitoring System for Partial Discharge of Electrical Equipment

The detection and fault identification of the partial discharge is the important aspect for the monitoring of the power equipment. For the lacks of the traditional detection methods, this paper analyzed the UHF signal characteristic parameters of the power equipment’s partial discharge, and developed the UHF detection system of the partial discharge. The A/D technology of the gain equalization ...

Medical Electrical Equipment

and could be read with profit by anyone interested in the problem of hydramnios. The Morphologic Manifestations of Uptake of Materials by the Yolk Sac of the Pregnant Rabbit describes how colloidal gold, erythrocytes, cream, and protein, in the form of egg white, are absorbed by the yolk sac. There are several electron microphotographs which are used to illustrate some of the processes. The Dev...

Fault Test Device of Electrical System Based on Embedded Equipment

The electrical system of the construction machinery usually works on circumstance of high temperature, serious vibration and shock, dust pollution as well as electromagnetic interference, so the electrical system is very likely to go wrong while compared with other systems, for example working attachment, under chassis and so on. In view of this, an advanced fault test device, with application ...

Testing New Alarms for Medical Electrical Equipment

This paper reports the first of several tests of new auditory alarms originally proposed by Block et al. [1] and formalized in IEC 60601-1-8 for use in medical electrical equipment. We test whether participants who are supplied with the IEC-recommended mnemonics while learning label-alarm associations can more accurately identify the alarms after short periods of learning. Results for 18 partic...
