How far below the frost line does a concrete footing need to reach?
A concrete foot generally must extend one foot below the frost line. in some cases it may have to be more or less.
What is voltage regulation formula?
The formula for voltage regulation is: Voltage Regulation = (V_no-load - V_full-load) / V_full-load * 100% where V_no-load is the voltage measured at no load, and V_full-load is the voltage measured at full load. The result is expressed as a percentage.
Is an ohmmeter connected in series or parallel?
You almost NEVER do. 1) The circuit should be off and/or disconnected when using an ohmmeter. 2) It should be in parallel with the component as far as the rest of the circuit is concerned, but alone in series with the device its measuring.
How many items will a 15kva electric generator support?
In theory, you should be able to load your generator to 15 kV.A (mine stalls far below that load, though!!!). So, divide this figure by the rated output voltage of the generator, and this tells you the maximum current it can supply. The sum of your individual loads should not exceed that value of current. (The current drawn by an individual load is its power rating divided by the supply voltage -just add them up!).
Why is generated voltage is not transmitted first?
The potential differences produced by an alternator at a power station are limited to around 25-30 kV due to the physical size required of such machines to accommodate the machine's armature conductors. These voltages are far too low for transmission purposes.For a given load, the higher the supply voltage, the lower the resulting load current. So very high voltages are required to transmit electrical energy, otherwise the resulting load current will cause (1) enormous voltage drops along the transmission lines, (b) large energy losses along the lines, and (3) the need for conductors with impractically-large cross-sectional areas (meaning they will be far too heavy to hang from transmission towers!).Accordingly, the voltage generated at a power station must be 'stepped up', using transformers, to very high voltages (in the UK, up to 400 kV; in countries where very large distances are involved, even higher than this). Energy at these voltages are then transmitted to 'load centres' (usually at the outskirts of towns or cities), where they are 'stepped down' to lower values for distribution purposes.
