… human power, which is delivered by the arms through the pushrims, with electrical motors, which are powered by a battery. The power assisted wheelchair is aimed at customers, who have used a regular wheelchair for a long time, but who have become weaker or just need additional …
… prefabricated concrete buildings for housing various installations, such as electric transformers.The aim of this dissertation is to reduce the time needed to design such buildings, by way of finding a number of standardized buildings. Standardized in such a manner as to …
… the majority of the heating systems are built up by different types of direct electricity, oil filled electric radiators and immersion heaters acting on a waterborne heating system.
… of methane gas, which is an energy rich gas that can be used for heat and electricity production. To receive a relatively large amount of gas, the decomposition requires a high moisture content in the waste. Therefore the landfill is dependent on precipitation input, although …
-en jämförelse mellan fjärrvärme och bergvärme i villa
… from other processes producing energy or waste, like garbage or chips. Electricity in combination with geothermal heating is another heating system that has increased sharply during the last years, and also this system decreases the discharges that have negative affects on the …
… the demand specification and was verified with the help of simulations. All electric schematics was designed with the guide of the design proposal. The pulses realized in the works of this thesis are those which Kitron experienced that they have a need to test in their own …
… networks is already a well tested solution in form of wireless controlled electricity meters so it shouldn’t be to much of a problem connecting these sensors to it either.
En studie av företaget Emotrons linjetestning i produktionen
… equipment to con-trol, monitor and protect processes and machinery driven by electric motors, with an applica-tion focus. Examples of uses for their products are fans, pumps, lifts and cranes. The project is to look at Emotrons end of line test. The company has seen that at the …
… on nuclear power plants. - Education and training in suppressing fires in electrical equipment. The probabilistic safety assessment strives to be as realistic as possible. Consequently this study recommends not giving credit for the manual fire fighting in some of the rooms …
… in order to reduce emissions of green house gases. Wind turbines generate electricity with low environmental impact, but the local opinion in Sweden is sometimes an obstacle to new developments. The acceptance of nuclear power increases at the same time. Mining uranium is once …
… to transfer to a factory. Therefore a study concerning if work related to electricity and electrical installation can be transferred to a factory has been executed. The purpose of the investigation is to study if any economical or time profits can be made. The method which was …
… possible. The reality is not so simple. Where you have to take more of the electrical details such as the effect on the transmitter as a major factor.
… new piston. Within this work a foundation was designed and the drive train, electric motor matched with inverter, for the rig was composed and mounted all together on the foundation. All of the parts that were designed during this work were also manufactured by the author. At …
… in accordance with the EU-directive 2003/54/EC, move from post-regulating the electricity power grid-tariffs by using a fictitious grid, to a regulation in advance which uses the actual power grid as a starting point. For this purpose a component breakdown of the grid needs to …
… system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs. In this thesis the following tasks have been …
