Thank Infomanic, but we still have some old-timers here think there's a difference depending on hertz, I'm not one of them. Ant published works on this? Thanks again.

I'm an electrical engineer in the US and need to clarify a dispute with a co-worker. We are working on a project in Russia where voltage and hertz are different from the US. We are sizing Generator Sets and have to calculate kVA to kW @ 50Hz.
What is the formula for converting kVA to kW for...
ccdubs,
I have to input my thoughts on this subject.
Caterpillar has led the industry in regulators with three-phase voltage sensing. Most Caterpillar generators are equipped to sense three-phase voltage. Three-phase sensing averages all three-voltage phases, resulting in better regulation...
Chuncky hope this helps.
CT Saturation
DC Saturation
When a fault occurs the current usually contains a DC component. The total flux required to produce the offset drives the CT into saturation.
Flux reaches saturation during the positive cycle and the exciting reactance decreases shunting...
mpparent, you equation only holds true if you have a unity (1.0)power factor. To accurately determine 3 phase ac you must factor in you pf.
I=P/(sq.rt(3)*V*pf)
Grounding
1. In any generator set installation, the frame of the generator must be positively connected to an earth ground or to the hull of a vessel. This connection is the first one made at installation, and the last one to be removed. If the generator set is on flexible or resilient pads, the...
An Automatic Transfer Switch is the least expensive way to go. I assume this is one (1) Standby Generator application. You would need to add acessories such as battery charger and jacket water heaters to ensure 10 second starting. I design these systems for a power systems company and if you...
need a calculation for sizing nitrogen piping with these parameters.
250 psig working pressure
11 cfm volume
-65 F temperature
418 ft. of run
also need info on pressure relief valves.
