This paper presents is to identify the causes for series reactor failures and to monitor and protect the 11 KV power system components and equipments from the harmonics and transients and other power quality related problems. Power quality is a major concern of our modern industries and other consumers. Poor quality of supply will affect the performance of customer equipment such as computers, microprocessors adjustable speed drives, power electronic devices, etc. and results in heavy financial losses to customers due to loss of production or breakdown in industries or loss of life in a hospital. The two major power quality disturbances are voltage sag and harmonic distortion. In the event of voltage sag, due to insufficient energy, equipments may malfunction or trip. Harmonics introduced by nonlinear loads can pollute the input supply to the sensitive equipments and cause the connected equipments to malfunction. In this paper, a Power Quality Provider is proposed and modeled by simulation with the help of external agencies meters.Keywords

Water management is a burning issue in Air Breathing Fuel Cells (ABFC). Flooding and dehydration are the two main degradation mechanisms that occur when water management is not adequate. In this paper, experimental studies on air breathing fuel cell with ducted and planar design on cathode side were studied, including experiments with three different ratios of cathode open area with each design, varying the channel dimensions in the ducted design and varying the current collecting and the open area in the planar design. In ducted design the mass transfer limitations and flooding can be reduced with wider channels, where as in planar design larger opening area reduce the mass transfer limitations however wide channels require a rigid gas diffusion backing with current collecting ducts. The effect of varying hydrogen flow rate, various cell orientations, various ambient temperatures of both ducted and planar designs were compared.Keywords
