Ability to ru motor/ geerator tests. Iheretly safe. Fully developed course curriculum. Computer delivery of curriculum materials. Modular format. Electrical power egieerig has for may years bee taught i a rather traditioal maer. Laboratory equipmet was based o large test sets usig aalogue istrumetatio. Computerisatio of these teachig laboratories that allows data acquisitio ad display of data has ot bee widely used. The ew PowerLab rage of products offers a moder approach to the study of Electrical Power systems, with full PC-based Virtual Istrumetatio, real-time plottig of machie characteristics, data capture, import/export of data ad direct pritig of results. Usig the ew data capture device it is possible to safely collect data from the system uder test ad preset this o the computer withi a stadard web browser. Data ca be displayed i real time as the test is beig carried out with the Dyamometer beig cotrolled automatically by the PC. Whe the test is completed the data ca be trasferred to a spreadsheet package for further aalysis or for itegratio ito studet reports. The system is supported by the Feedback Discovery II Laboratory system. Discovery II Laboratory has the followig features: Uique combiatio of Computer Assisted Learig Material (CAL) ad hardware with itegral Computer Based Traiig (CBT) laboratory exercises, combiig VIRTUAL INSTRUMENTATION ad REAL TIME MEASUREMENT. Authorig tool eables tutor developmet of additioal learig material to meet diverse traiig requiremets. A studet maagemet system that cotrols access to the learig materials ad tracks the studets as they work through the material recordig their performace as they progress. PowerLab offers a wide rage of subject coverage from a series of teachig packages. Each of these packages has a set of laboratory equipmet desiged to provide practical uderpiig of the theory. Each of the PowerLab modules is available separately allowig other equipmet sets to be created. Discovery II software allows teachers to create their ow course profiles through the likage of a series of learig objects. For those who still require covetioal istrumetatio PowerLab offers a wide rage of istrumets. The teachig materials have bee writte to reflect both types of istrumetatio.

2 Complete System PowerLab with Virtual Istrumetatio Complete Electrical Power ad Machies system. Available with or without Virtual Istrumets. Complete power egieerig courseware. Cost effective modular system. Expadable with covetioal ad electrical cotrol accessories. PowerLab is a complete system that covers the majority of the curriculum requiremets of Electrical Power & Machies. It is based o a series of idustrial machies of omially W ratig which have bee purpose desiged to display characteristics typical of larger machies. The system also covers Sigle ad Three Phase Trasformers ad Electrical Techology. The Traier is complete with the ecessary power supplies, loadig ad testig devices ad PC virtual istrumetatio for the meterig of all the systems values. Virtual Istrumetatio with a mix of aalogue ad digital readouts. Four plots geerated by the automatic plottig tool showig families of curves at differet levels of iput power supply. Detailed laboratory otes are provided, which cover experimetal operatio ad practical traiig o: Electrical Techology. Sigle Phase Trasformers.
