Answer / vivek
When Diesel generator overload its freqency reduce fron set
value ,so RPM of dg decrease as result .Fuel governer
direct control the speed of engine .when sensor actuate it
stop the engine.

Answer / lokesh
Even diesel gen cannot hold the over load when it reaches
perticular load it tripps for safety purpose
| Is This Answer Correct ? | 4 Yes | 4 No |
Answer / mubanga mulenga
its because it reaches past its steady state stability
limit, delta 2, so it will swing out into trip.

Answer / deltawye
the diesel generator set will shutdown during overload is
because of its voltage regulator
| Is This Answer Correct ? | 0 Yes | 1 No |
Answer / sarfraz
In my views
for few second it will support then safety operate and it
switch off the genset

I hv a question regarding power factor improvement just after transformer. I request you to reply me plzz. thank you sir. My friend has a small unit of fabrication. in his factory the main load is a welding machine, lathe machine, grinding machine. this load is not continuous type. now our electricity board has installed 16 KVA, 11000/433 V transformer for our factory. In the energy meter (trivector meter) at LV side of transformer, i hv seen power factor value of 0.15 only when only 3 KW load was flowing. Further electricity board has suggested to install 4 KVAR capacitor at LV side after energy meter. Now my question is that if we permanantly install and switch on 4 KVAR capacitor after energy meter, during some load on transformer and also without any load on transformer, wht will be the power factor shown in energy meter?i dont want to get any penalty by electricity board, so plz suggest me if i can permanantly install and switch on the 4 kvar capacitor or not at LV side of transformer just after energy meter? Thank you again and awaiting for ur positive reply soon.
How does the sensitive earth fault protection provided by cbct for motor can help in reducing the size of cable used to supply the motor?
i am going to correct power factor of 1600kw induction motor,when i calculate capacitance of capacitor it is three time more in star connection than delta. if motor is star connected which connection i shall adopt for capacitors and reason for adopt this connection
I need HT sphere gap calibration table. Can any body help me.
