Hi pumps,
Refer to your answer I can summarize if IP 55 in my motor name plate will be cover for enclosure motor as well as terminal box.
The basic philosophy for IP code are:
- 1st digit for protection against finger and solid object
- 2nd digit for protection against water.
Let say, I want...
I am starting to curious with this one.
Usually, when we purchase motor, it will shown IP (Ingress protection) code on name plate. Let say, example, IP 55. In my understanding and also what I taking from catalog, IP code in here means enclosure protection. Enclosure means motor sealing.
How...
Zanoter & Waros,
I try to make summary if your answer is Heater.
For the first type of installation (non dry air pressure injected) we will plan to install heater.
However, for the other type where bus duct will be injected by dry air pressure, we dont want to install heater. Any concern?? Any...
Refer with IEEE C37.23 section 7.6, Seal or Frame will be installed to separate section inside outside building. The bus duct having sections located inside and outside a building, so that ambient temperature may be appreciably different at the same moment. Sealing or baffles shall prevent an...
Dear All,

Dear Eti & Vandala
I have attached files for your reference.
You could be get more information at vendor website.
Vandala,
ETAP get their typical data from ETAP Library refer to ANSI/IEEE or IEC standard...
Dear Rodmcm,
I am not agree. Engineering document call this "N+1".
Anyway, It's difficult to set fast acting load sheding for Generator using "mechanical governor" instead of "electronic governor". As far as I know to parameter that you shall be consider are "voltage" and "frequency".
For keep...
Hi Eti,
You could find at vendor catalogue.
Try to find at Siemens, Cummins, Yanmar, Caterpilar, etc.
For preliminary modelling you can use "typical data" at ETAP library.
ASAP, If I find the data I will send to you.
yap.. I am also agree.
Its realy depend on your purpose.
But, one thing you should be consider is price.
Some of special transformer / optional transformer is expensive.
Currently, we are develop electrical system in a small platform. It will be fed from DC Generator/CCVT and 24V DC main battery bank.
For special condition will fed from emergency generator 400V AC.
Therefore we put some of DC/DC Converter 24 VDC, Inverter 24/230.
As you know, usually inverter...
