"Condition monitoring of engineering plants has increased in importance as engineering processes are automated and manpower is reduced. However, electrical machinery receives attention only at infrequent intervals when plant is shut down and the application of protective relays to machines has also reduced operator surveillance.A first edition of Condition Monitoring of Electrical Machines, written by Tavner and Penman, was published in 1987. The economics of industry have now changed, as a result of the privatisation and deregulation of the energy industry, placing emphasis on the importance of reliable operation of plant, throughout the whole life cycle, regardless of first cost. The availability of advanced electronics and software in powerful instrumentation, computers, and digital signal processors (DSP) has simplified our ability to instrument and analyse machinery. As a result condition monitoring is now being applied to a wider range of systems from fault-tolerant drives of a few hundred watts in the aerospace industry, to machinery of a few hundred megawatts in major capital plant.In this new book the original authors have been joined by Ran, an expert in power electronics and control, and Sedding, an expert in the monitoring of electrical insulation systems. Together the authors have revised and expanded the earlier book, merging their own experience with that of machine analysts to bring it up to date."

"Generator induksi sudah mulai banyak dikembangkan, dikarenakan generator induksi memiliki banyak kelebihan. Generator induksi dapat diperoleh dari motor induksi dengan cara memberikan suplai daya reaktif kedalam motor induksi. Pada penelitian ini, dilakukan perancangan mesin induksi dengan kapasitas 100kW. Simulasi dilakukan tiga tahap, yaitu: pada tahap pertama melakukan perancangan motor induksi. Pada tahap ini melakuan desain dengan menentukan hubungan antara jumlah slot stator dan rotor untuk mendapatkan desain yang optimal, dengan membandingkan masing-masing desain, apakah hasil simulasi dari masing-masing desain sudah mendekati dengan daya 100 KW, efisiensi dan faktor daya yang baik. Tahap kedua adalah melakuan optimasi disain yang dipilih dari tahap pertama yaitu dengan memvariasikan jumlah lilitan, lebar celah gigi, dan kedalaman slot rotor, dan tahap ketiga melakuan simulasi uji mesin induksi sebagai generator.Dari hasil penelitin bahwa variasi jumlah lilitan stator dan rotor, lebar celah gigi dan kedalaman slot rotor dapat mempengaruhi daya keluaran, efisiensi dan paktor daya. Pada penelitan ini berhasil mendapatkan desain yang diinginkan yaitu sebesar 102 KW dengan efisiensi 94.39 dan faktor daya 0.896. sedangkan pada pengujian mesin induksi beroperasi sebagai generator, berhasil dilakukan dengan exitasi 150 A dengan putaran 825 rpm, daya yang dibangkitkan sebesar 114 KW pada tegangan output 234 Vrms.

Induction generator has started to be developed because induction generator has many advantages. The induction generator can be obtained from the induction motor by providing a reactive power supply into the induction motor. In this research, the design of induction machine with 100kW capacity. Simulation performed three stages, namely in the first stage of designing an induction motor. At this stage do the design by determining the relationship between the number of stator and rotor slots to obtain the optimal design, by comparing each design, whether the simulation results of each design is close to 100 KW power, efficiency and good power factor. The second stage is to design the optimization of the design selected for the first stage by varying the number of loops, the width of the tooth gap, and the depth of the rotor slot, and the third stage performing the simulation of the induction machine test as a generator.

From the results of the research that the variation in the number of stator and rotor windings, the width of the tooth gap and the depth of the rotor slot can affect the output power, efficiency, and power factor. In this research managed to get the desired design that is equal to 102 KW with efficiency 94.39 and power factor 0.896. Whereas in the induction machine testing operates as a generator, successfully done with excitation 150 A with the spin of 825 rpm, power raised equal to 114 KW at output voltage 234 Vrms."
