Although there are still uncertainties regarding the extent to which climate change may be occurring, some approximations and reasonable assumptions can be made relating to daily high and low temperatures. Further, urbanization may impact ambient temperature. These temperature models may be used with standardized methods to estimate the loss of life of oil-immersed power distribution transformers. In this way, the impact of increased ambient temperatures on distribution transformer loss of life may be preliminarily assessed. Results of standardized engineering studies for illustrative cases are shown in this paper.

Als Kogeneration bezeichnen wir die gleichzeitige Ausnutzung des optischen und thermischen Teils des Sonnenspektrums durch elekrooptische und warmetechnische Mittel.

Das Prinzip der Kogeneration

Significant developments during 1988 are reviewed. Growing demand for electrical power in the US is motivating the use of technologies, such as high-voltage direct-current (HVDC) transmissions. Significant milestones were reached in so called clean-coal combustion technology, the use of batteries for storing energy for times of peak demand, and the efficient conversion of solar energy. Concerns for the earth's climate and environment, particularly global warming, has meant a much-needed boost for projects to develop safer nuclear reactors. Plans to further utilize two of the world's great hydro resources, the Amazon basin in Brazil and James Bay in Quebec, Canada, were advanced. >
