(OP)
Is anyone can tell & explain to me what is the proper of load test of the generator using water resistance bank. we have 3 gen set, are we going to test individually and take all the parameters ( voltage, current, kw, freq, pf, engine datas such as cooling water temp, exhaust etc) with 25%, 50% , 75%, 100% & 110% load. OR 3 generators to be in parallel operation and take all the parameters on each gen with above mentioned load percent. pls to hear form anyone. thanks in advance.

The size is important as the time relates to the volume of the water.
Example would be a dumpster. Add water. Suspend the electrodes so they don't touch the sides even if wiggled or pushed. Then add salt until you get the current you want. Add slowly as you need to give time for dissolving. Also as the water heats the conductivity can go up. Don't move too fast.

But, if you have an automatic float valve to maintain the water level, the load will be fairly stable with the water boiling. If you suspend the electrodes from a fork lift you will be able to easily make adjustments. I have used old leaf springs from a small truck as electrodes with good results.

Individual test is just part of the overall test. If you want to know if the 'system' work properly at load and load sharing between generators, etc., you need the system test.

I've seen units "fail" site testing due to improperly sized mufflers, air flow blockage to radiators, insuffcient air to the engine room, and running out of fuel because the day tank supply pump was improperly sized for the engines fuel burn rate.
Hope that helps

jalover:
Why do you want to perform an individual load test at all? Your type of gen set (250 kW) is of standard size and such tests must have been carried out lots of times on such units. Ask the OEM for test reports.

You can save many bucks of equipment that you will use only once. Only need to ask permission to do it depending where are you.
