Why not parallel to the grid? You can export as much Kw as you need to load test your units and not need to spend money in equipments that you will use only once.
cloonypan,
The droop function is used only when genset is paralleled. In island mode, the generator working alone, this function should be canceled (droop potentiometer fully counterclockwise), in order not to affect stability.
Submersible pumps must be protected to detect dry running and cavitation. There are adequate protection relays to do so. See the link below

Liam,
You will get about 7.5 KVA.
(M) is middle point. To be used only if there are 120V circuits to feed. In this case you can ground it.
For 240V use the neutral will be one of the lines (L1) or (L2). Be careful to isolate the generator from the grid. Use a change over switch.

As catserveng said:
"You only load bank tested with a resistive load, so you did not qualify voltage droop, is the droop transformer in the generator (or switchboard, sometimes called the cross current transformer) installed with the correct polarity? Your inital description sounds...
Any maintenance work was done before this incident happen
like cleaning of air filters?
Check if any rag was sucked by the turbochargers
Check water in the fuel
Your droop setting is wrong. Try to adjust each set to 4% droop. To do so turn the droop pot fully counterclockwise, load individually each set and adjust droop pot to get 4% voltage droop at full load. You can make it proportionally, if you load the set at 50% adjust the pot at 2% voltage...
In the 2.5MVA 11kV/415V Dzn0 transformer, the LV phasor is in phase with the HV phasor while in the 2.5 MVA 6.6kV/415V, Dyn11 transformer the LV phasor leads by 30 degrees the HV phasor, so you cannot parallel both transformers.
Cat sizes their generatrs differently between 60 and 50Hz.
There are arrangmets with different radiators, fans and driving pulleys. Agreed thas is also a turbo question.
