Electrical Wiring

Without knowing the maximum output current it was designed to produce it isn't possible to say exactly how much voltage a charger produces. Also, was it intended to give a slow or a fast charge? In general all that can be said is that the output voltage of a battery charger must always be slightly higher than the nominal voltage of the battery it was designed to charge. This is for the simple reason that it won't be able to put any charge into the battery unless the charger's "on-load" voltage is higher than the battery's voltage. For the same reason, a charger which can deliver a high output current (amps) will need a higher "on-load" output voltage than a charger which can only deliver a low current. Also, when it is switched on but is not connected to a battery, the output voltage of any charger will always be higher than when it is doing its job of charging a battery. That voltage is called the "no-load" voltage. Assuming the battery being charged is a standard low-voltage type, of less than, say, 24 volts DC, it is quite safe, using a standard electrician's voltmeter, to measure the load and no-load voltages of the charger as described above.

Well, voltage and current levels being identical, alternating current would be safer. It does not spend 100 percent of its time at peak voltage, therefore the average power in case of an electric shock is lower than that of direct current, which is 100 percent. This lesser average may allow some time to detach from the circuit and may not cause such catastrophe to the body.

an alternator is essentially a generator that converts the kinetic energy from the combustion engine in your car into electrical energy to recharge your battery. To answer your question about connecting a generator to another generator to create limitless energy there is always a loss of energy during the conversion process usually due to friction. In theory it is possible but there is no pure conversion of one form of energy to another in real world application. There will always be a loss of energy in some form.

The sizing of transformers is based on an accumulation of all of the loads that will be connected to it. Add up all of your loads and possible loads in the future and then tell your installer the figures and they will use these to calculate the size of the transformer that is needed.

The waveform from a half wave rectifier looks just as it is described by its name: half of a full sine wave. That will cause a pulsed or "ripple" effect in the output voltage and current that come out from the rectifier.

Whether that will cause a problem depends on the application you are using.

For instance, if it is a light bulb, it will appear to flicker at the frequency of the alternating current service that has been rectified, which can be very annoying!

If it is a device such as a charger for the battery of a digital camera or an electric shaver, the pulsed output current doesn't matter at all.

The common household electrical service is usually rated as a single phase service. In North America there are a few 120/208 three phase services being put into larger homes.

Yes there is single phase for 600 volts. It is used for lighting. You need a transformer which gives you 600 volts plus a neutral. The voltage for the one phase to neutral is 347.

The most common wire size for an extension cord to use would be a #14 conductor. As extension cords are classed as flexible cords, the proper terminology would be a 3C/14. The cord consists of three #14 conductors, whose colouring is white, black and green covered by a plastic sheath.

You can not unless the installation is a motor and cost is not important. Depending on the amount of money you want to spend to make this happen there is a device on the market called a VFD ( Variable Frequency Drive). On the three phase input terminals you apply your single phase voltage. On the output terminals you connect your three phase motor. When run in this configuration there is an internal switch that has to be changed to let the VFD know that it should be looking for only two lines on the input to be hot. Other wise the VFD thinks that there is a line loss on the three phase input terminals and the unit will not start.

1. Context diagrams are small and will fit on one page.

2. Use the name of the information system as the process name in the context diagram.

3. Use unique names within the other symbols.

4. Make the process named after the information system 0.

5. Identify all the entities.

6. Identify all the names and content of the data flow.

7. Identify the direction of the data flow.

8. Draw the diagram using appropriate symbols.

The center terminal of a variable resister is called a wiper.

Copper is used in electric wires because it is the best conductor of electricity that is known, apart from silver which is slightly better. For overhead wires a common material to use is aluminum because it is much lighter, although not such a good conductor. Overhead high-voltage wires usually use aluminium stranded wire with one or more steel strands in the centre to give strength.

A steamboat uses a steam engine similar to those on a steam locomotive. An external wood or coal fire heats water in a boiler, and the pressure of its expansion into steam is used to turn a shaft that is connected to paddlewheels, or to a propeller blade.

Steamboats were the first alternative to sailing vessels, and replaced them as the major form of marine vessels. Modern steam turbines (invented in 1884) continue to be used for the generation of electricity worldwide.

By the phrase "trips the heaters" I am assuming that you meant the Overloads. There are 3 possible answers: 1) The Overloads are not the correct size or are in a high ambient temperature envornment. Most manufacturers have sizing charts that take these into account. 2) The motor is bad or in the process of going bad. 3) The motor is overloaded. If you are running a 7 1/2 HP motor on a load that requires 10 HP then the motor will draw too much amperage and trip the overloads.

408 volts x 1.73 = 277 volts is the star ( Y ) point of 3 phase 480V. A transformer connected in a Delta configuration is different than a Y or Star configuration. 277 volts is a voltage that is used in industrial plants usually for lighting. The following link will explain the whole star delta connection. http://www.allaboutcircuits.com/vol_2/chpt_10/6.html

The standard height they are placed is no more than 48" above the floor. I mount my switch boxes with the top of the box 48" above the floor. You can install them lower if you wish but no lower than 15" above the floor.

An autotransformer (sometimes called autoformer)[1] is an electrical transformer with only one winding. The winding has at least three electrical connection points called taps. The voltage source and the load are each connected to two taps. One tap at the end of the winding is a common connection to both circuits (source and load). Each tap corresponds to a different source or load voltage. In an autotransformer a portion of the same winding acts as part of both the primary and secondary winding. Operation he ratio of secondary to primary voltages is equal to the ratio of the number of turns of the winding they connect to. For example, connecting at the middle and bottom of the autotransformer will halve the voltage. Depending on the application, that portion of the winding used solely in the higher-voltage (lower current) portion may be wound with wire of a smaller gauge, though the entire winding is directly connected.

You need the input voltage and maximum input current specs found on the name plate.

The excitation voltage is too low. Turn the field voltage "pot" to raise the field voltage while watching the output generator voltage.

Two reasons could be that the motor was wired incorrectly or the load that the motor is driving is too heavy for the HP of the motor.
