NETLAB-An Internet based laboratory for electrical engineering education

INTRODUCTION In electrical engineering, laboratory experience is an integral part of the educational process. In fact, the amount of resources required to design and con-struct innovative experiments for electrical engi-neering education is relevant, and the number of in-stallations is often limited due to economic factors (Corradini et al., 2001). As a result, the possibility of experimental training for all the students is extremely reduced. With the rapid progress of Internet technol…     

鲜切茭白短期贮藏过程中的电导率变化

新鲜茭白经切片等处理后,于冷藏(1℃)和常温(20℃)下包装贮藏,在贮藏过程中对两组切片的电导率进行测定,结果显示:随着浸泡时间的延长,电导率不断上升;在常温下,从第3d起,电导率迅速上升,而在冷藏条件下,前3d电导率持续下降,随后也迅速上升.在整个贮藏过程中低温贮藏下切片的电导率明显小于常温贮藏下切片的电导率.     

Testing results analysis of contact materials＇ electrical contact performance

Because of the different ways in which contact materials work, the basic requirements for silver metal oxide contact materials are different. They are anti-welded and anti-erosion when closed, anti-erosion when broken, and arc easily moved and have smaller contact resistance. In this paper, La2O3 is used as a stable oxide in contact material to replace CdO. A new type of Ag/SnO2-La2O3-Bi2O3 contact material is first obtained through using powder metallurgical method. Then electrical contact material parameter tester is used to test the electrical contact performance of the contact material. Through experiments, the arcing voltage and current curves, arcing energy curves, fusion power curves while broken and contact resistance while closed were obtained. Analysis of the results showed that the addition of La2O3 makes the contact material have the following advantages： smaller electrical wear, smaller arc energy, smaller contact resistance and arc is more easily extinguished.

Investigation of oil-air two-phase mass flow rate measurement using Venturi and void fraction sensor

INTRODUCTION Accurate measurement of multiphase fluids flow rates in the petroleum industry is of great importance. The most reliable measurement technique for multi-phase flow is separating the mixture and using con-ventional devices for measuring single-phase flow. However, in many cases the separation is not practical from both technical and economical points of view. An alternative solution is the multiphase flow me-tering system, usually consisting of a combination of devices for ph…
