There are many ways to kill a cat ! ! !
1. How many electric cars are there in the town you are thinking of installing the chargers.
2. Get the battery details.
3. You can use the Mains or the Solar power to charge the battery.
4. Is sunshine available through out the year?
5. We can supply you solar powered battery chargers and save on the grid power.
6. Interested? contact mizunsolar(at)ymail dotcom to discuss further.

Any Power Plant Consultant charges 5% of the total project cost to do the power plant design and engineering. This 5% starts from as low as US$ 10,000 to anything in millions of dollars.
You should ask your professor to help you out. Even if you hear from anyone, the information will half baked and incomplete. This may mar your educational prospects.
Plan with your class a visit to the nearest power plant and note down the equipment you see and discuss with the engineers you meet there.

If you load 2tons on a truck of 18 tons, where does 16 tons go?
If you can answer this, you have answered your question.

In any hotel, there are so many ways to save on utility expenses.
1. Lights in the parking / Garden / Pathway area. You can opt for Solar Lights for these areas. We design and supply them.
2. You can install a CHP unit which will greatly reduce your consumption of oil and gas. How this works:
You install our CHP Plant. The Boiler can be fired by oil or gas. The boiler produces steam. Steam runs the generator through a turbine. The steam exhaust is sent to heat the space or heat normal utility water.
3. To know the capacity of power generation, tabulate the bill of last 12 months and we will know the peak requirement.
4. Send to mizun(at)ymail dotcom all the information you have on your utility consumption for us to study and revert back.

dear mr vissu
HELLOO!!!!!!!!!
now you must be aware that maintaining unity p f is very advantages in many ways. if you are in some states like maharastra or gujrat you can avail an incentive of 7 % max instead of a penalty of 7 % on your running monthly bill. your supply/load needs to be studied like wise to design a suitable capacitive compensation. SO MANY MORE ADVANTAGES ARE ALSO THERE.

will kvar effects generation & transmission
hi I need some electrical project to do can you help me
Dear,
this is the code for a component or a device. 3 is for three pole, TF is the type of contactor and 35 & 47 is the current carrying capacity of the conteactor, or in other words we should be say it that 35 & 47 is that ratting witch we operates for the load for 35 Amps. and 47 Amps.
by knowing internationally accepted standard electrical symbols you can easil read the drawing
hi friend.. i will give you some articles…i am sure it will help you to read an electrical drawing..
We have designed and supplied Harmonic Filters across the length & breadths of India and Worldwide and by now have completed over 500 projects involving over 150 clients encompassing almost all Industry segments.

I am hoping each motor will have its own circuit from a distribution board, otherwise all the following will not be valid and the installation is questionable at best. ie Power supply feed to four circuit breakers, one for each motor.
I can only provide australian details. Firstly, is the 220 volts single phase voltage, or 3 phase? This will determine amps per phase and thus cable sizing. If you're only a little bit lucky the motor should have a nameplate amp rating on it, this will be the amps per phase and will mean you won't need to know the phase voltage.
If 220 volts is 3 phase then you're looking at approx 98 Amps for the 40HP/30kW motors, and 59 Amps for 25HP/18kW motors.
You have to consider voltage drop, typically allow 3% (6.6 volts) drop to motors, and total 5% (11 volts) over entire circuit. 25mm copper cable over 30 metres will be ok for this as only approx 4.5 volts drop. 7.1 volts drop with 16mm copper. (4.3 volts drop using 16mm copper for the 25HP motor).
Next check current carrying capacity – for 98 Amps buried direct (not in conduit) 25mm is 162 Amps, so again OK. 16mm current carrying capacity is 125 Amps. If in conduit and buried current capacity drops to 123 Amps for 25mm, and 95 Amps for 16mm.
Now check to see if the cable will hold up in case of short circuit. Earth cable on standard 16mm is 4mm, and 25mm has 6mm earth. Check sum allows circuit length of 34metres for 16mm cable. However the 25mm will only just (less than 1 metre) allow this circuit at 98 Amps over 30 metres. This means that over only 30 metres the resistance of the cable is low enough to ensure sufficient current to trip the circuit breaker in the event of a short circuit within a specified time. If the motors are not running at full load you could use a smaller circuit breaker (ie 80 Amps) or you should go up to 35mm cable.
Are the motors in a hazardous area? If not, why use armoured cable? If so, make sure you use the appropriate glands. In Australia & New Zealand, the cable must be insulated and sheathed (whether or not it is armoured) to be buried without conduit and must also have 50mm of sand/friable soil surrounding the cable, be 500mm deep, with a plastic cover (polymeric) providing mechanical protection (from the likes of shovels) less than 75mm above the cable and marker tape at approximately half depth.
Good luck
