    Generator Exhaust Pipe Re-routing

    Thank you again. Water accumulation is a very strong argument not to route an exhaust pipe underground. I totally forgot this point. Aziz Ozmine Electrical Engineer

    Generator Exhaust Pipe Re-routing

    Thank you very much Mike, for your valuable answer. Yes, there is a silencer that we received with the generator. And no, we don't have an additional budget to make all those changes. There is already a design for the exhaust pipe and it is supposed to penetrate the 2nd and 3rd floor slabs...

    Generator Exhaust Pipe Re-routing

    We have a generator on the 1st floor of a building under construction and the original design asks for an exhaust pipe going up to the roof of the building (Building has 3 floors) but our project manager is looking for another alternative to re-route the exhaust pipe. He actually wants the...

    Generator with Voltage at Neutral?

    Waross, I did not mean to discourage you. Your questions were not silly, if I wrote something that made you feel like this, I am sorry. Maybe this is because english isn't my first language. I know about this grounding and neutral problems and I sometimes have difficulties to explain the...

    Generator with Voltage at Neutral?

    For me, a ground is a ground and a neutral is a neutral. Even if I come accross with a system with grounding and system neutral connected together, a seperate grounding cable should be connected to the ground connection of the unit to be energized. Anyway, after meger measurement (waiting for...

    Generator with Voltage at Neutral?

    One moment, one moment. No load was actually connected to the ground. A ground is a ground, right? It is our PE (Protective Earth). In our case, the system was PE+N; i.e. PE and N was not connected together. That is OK. The generator is a 150kVA, 376A, 3-phase generator. While making the...

    Generator with Voltage at Neutral?

    Waross, I have the problem there even when the load is disconnected. I did all the measurement while the load was isolated from the generator.

    Generator with Voltage at Neutral?

    Well, I disconnected the load to see that the failure was not coming from the load side. It is not. But I have not disconnected the short wiring between the alternator and the generator panel. I can not see this wiring completely. A small possibility but maybe, the insulation of phase3 cable has...

    Generator with Voltage at Neutral?

    I have some difficult times at a construction site. One of the generators which generates power for some part of the site has voltage at its neutral and its grounding connection (while the ground cable was disconnected). We found out the problem yesterday by chance when an electrician got an...

    60Hz vs. 50Hz

    Thank you all. Your answers are very helpful. Waross, Both the fan motor and the burner motor has nameplates on them on which I can read two different ratings, one with 460VAC at 60Hz and the other with 380VAC at 50Hz. I think, the motors are designed for both 50 and 60Hz as Vladpl suggests...

    60Hz vs. 50Hz

    Hello Everybody, I am working in a construction site in Kazakhstan where it is extremely cold outside and therefore the mobile heaters are used to heat the construction area. Lately we received two new 2million BTU heaters from USA, but they are delivered without their own generator on it which...
