    Field Measuring High DC Current

    Just a very simple basic suggestion: Maybe you can make use of the existing resistance accross one of the joints/connections, or even a part of the cable, in your DC powerline. Since any connection has some sort of a resistance, you will be able to detect a (low) dc voltage which is linear with...

    caterpillar digital regulator for generator

    Motorxplosion, Is your question still actual? I think that the regulator you have seen is a DVR (Stands for Digital Voltage Regulator). If required I might be able to help you with some documentation.

    Standby Generator performance

    Sorry to say this PAFred, but this doesn't answer the question at all! The question was what amount of load step can be performed AS A PERCENTAGE of the full load rating. This is depending on several items, such as engine BMEP, whether the engine is turbo charged, moment of inertia, governor...

    Temperature rise calculations for generators

    Hi, Just be informed that insulation class F generator, utilized for class B, is a requirement according to the Shell DEP's and the Norwegian NORSOK standards. The motivation is to save the insulation varnish due to the normal operating temperature (B) which is far below the max. allowed...

    Temperature rise calculations for generators

    Thanks, it seems to be very helpfull for me. So a portion of the losses do NOT vary with the square of current. 1) Is this caused by the magnetic losses, converted to heat? 2) Is there a rule of thumb to estimate the value of "alpha", or can this be calculated as well?

    Temperature rise calculations for generators

    For a new project we have to supply generators with class F insulation, utilized for class B. (So the temperature rise may only go up to temp. rise B temperature) The only way to achieve this requirement is to select an oversized generator. Is there a way to calculate what the amount of...
