My first question is given under title :
(1) How far must be direct buried power cable from the existing benzene pipeline.
My owner is suggesting something what I am not accepting - he want to use abandoned Benzene Pipeline as metal conduit for 600 Volts power cables inside industrial area...
The Owner is preparing to use abandoned Benzene Pipeline as metal conduit for 600 Volts power cables, all inside industrial area.Pipeline is very old, abandoned for many years.
I don’t like this idea, but I have to check something :
(1) Can we accept abandoned benzene pipeline, cleaned up with...
Owner is preparing to make new Communication Tower inside Power Plant, too far from any Grounding Grid.
Tower must be grounded with 4 ground rods /square layout/. That what must be provided is Ground Resistance R = 5 Ohms minimum. Soil is good - no sand, no stone. If Ground Resistance is R > 5...
Existing dispatching building with 208/120 V and existing communication tower
are provided to be upgraded and put into operation.
Information about existing grounding doesn't exist and new grounding is
provided to be installed
(1) four ground rods are provided around building
(2) three ground...
Project provides an installation of a small building where HYDROCARBON ANALYZER has to be installed.
Hydrogen has to be used as "fuel" for the HYDROCARBON ANALYZER providing an ionization of the gas samples.
Small vent-chimney is installed on the top of the building.
MY QUESTION ...
Hydrocarbon Analyzer is it a hazardous area device ? The analyzer is provided to be installed in special room for the monitoring of hydrocarbon contamination. That room is potential hazardous area, and Owner wants to discuss about that.
I used to read many prospects / catalogues about...

IEEE 841 is Standard for Chemical and Petriochemical Industry.My customer wants to see 3/4 HP motor designed to meet IEEE 841 Standard. One comment sent to me is that 3/4 HP motors are not provided for that standard. Who can tell me is it true or not ? / I do not have here standard /
Sincerely...
Did you ever work with heavy motors such as 4160 Volts, 900 HP. Specially what I need, are info about specification of this equipment. Also info about starters and protective relaying are welcome.
Last couple months I am member of this FORUM and I am fascinated by the quality of this WEB SIDE.
Question :
How to find a similar FORUM for Architects, specialized for buildings etc.
We started a project with an idea to install explosion-proof electrical rack, for small power distribution (with min.C.B.'s or fuses) close to the existing benzene line ( distance, d=15 feet - from flanges)and new benzene line (distance, d1=21 feet from flanges and control valves).
Now customer...
The idea was to install explosion-proof electrical rack, for small power distribution (with min.C.B.'s or fuses) close to the existing benzene line ( distance, d=15 feet )and new benzene line (distance, d1=21 feet).
Now customer want unclassified electrical panel,( non explosion-proof)...
The client is trying to install switching devices ( fuses)in hazardous zone - zone 2, what is not acceptable to me. The distribution voltage is 240V.
They are trying to explain that encapsuled device (fuse) can be acceptable solution.
a) I didn't find proper manufacturer making this product in...
I have to provide a Line Voltage Conditioners to be installed in HAZARDOUS ZONES expecting Division2 products.
(1) I need information about any manufacturer making these products.
In many cases epoxy encased transformers, can be good for the Div.2 hazardous zones, but here the situation is much...
The price of the Short Circuits Calculation Softwares depends from many reasons, first of all from the number of the buses ( 100.000 buses can not be the same as 100 buses).
THAT is what I need a small software for SHORT CIRCUITS ANALYSIS for 100- 200 buses.
How I can find this software ???
Thanks.
Did you make Grounding of Antenna Communication Towers ?
As Electrical Power Engineer I have to work on this package, but not informed about that field. Any internet link is welcome. I heard for Motorola Handbook R56. How to find this materials ?
The Communication Tower ( 80 ft) must be grounded and protected from the lightning. Is it the same as for the building ? What about 230 kV transmission line passing close to the tower. How far it can be ?
Tnank you for the help. Any text on the internet ?
