Around 10 photovoltaic solar panels fixed on AL structure is installed ground loop. Another ground loop is 100ft away around control house where are installed AC and DC O/C and surge protection.
These two loops are connected with two conductors creating third loop.
My manager is suggesting :

The project of mini PV solar station provides an installation of the ground loop around 10 solar panels + metal supports where lightning protection (two lightning rods) is provided to be connected with a grounding. All metal parts (panel frames, metal structure etc.) will be bonded and grounded...
Transformer Bushing Ratings
I am checking Transformer Specification for one project where Transformer Bushing Rating Data are presented. That what I don’t understand there is a sizing of the Transformer Neutral Bushing .
Based on IEC 60137, for 500 kV transformer, following data are...
I am working on the project - 44 kV outdoor switchgear where conceptual design provided an installation of three CTs plus three VTs on the same support - steel structure.
CTs will be series connected as usual. My question is how far PTs have to bi installed from the CTs i.e CT-R, CT-Y and CT-B...
Reading a some articles about Distribution Generation Benefits I found that
-Distributed Generation improves reliability
-Distributed Generation improves safety
Can somebody explain to me
(1) How or Why Distributed Generation improves Reliability ?

Presently I am working on Distributed Generation Project, and I need an article where Fundamental of WIMAX Communication System is given in short text.
Thanks
I am Mechanical Engineer working for Engineering Company in Canada( Government Job) on the lowest position of Engineer - Design Engineer, where P.Eng. status is not obliged, but as P.Eng. I approved many times drawings based on request of my Manager or Lead Engineer. They are also Professional...
Why Newton Raphson Modeling based on power loss minimization and retaining of bus voltage limits is not acceptable for the calculation of sizing and placement of distributed generation. Is there any good article to read more about that ?
What is difference between nuissance trip and false trip for distribution network with distributed generation ?
Some authors are specifying these terms as different.
I should have to install three 115 kV capacitive voltage transformers inside my substation on line side of 115 kV disconnect switch. Also, I am informed that I have to install three line arresters on the same - line side of 115 kV DS, because CVTs are provided on the line side, not substation...
For the small article what I have to prepare as Word (.doc) document, I want to insert two/three simple Single Line Diagrams
( breaker, transformer, recloser, buses, short circuit symbol etc.)
How to do that ? Also, how to insert there a text tagging transformers (T1,T2), buses (B1,B2) etc. ??
I have to replace 28kV 1250 kcmil PILC cable with XLPE cable. That was good as long as I calculated with 100% insulation level.
Now I found that my 28kV side is grounded through the reactance what means that 133% insulation level must be provided.
Unfortunately, I can NOT find any vendor...
I have to make inside 15 kV Metal-Clad Cubicles (Cells) Cable Potheads Replacement by Cable Terminations. ( for PILC paper insulated lead shield cables ).
If I cut my cables below potheads - I have only 400-450 mm of cable length.
Can I open my potheads and these parts of conductors inside...
Based on IEEE515 I caculated Heat Loss of the vertical Vessel (natural convection, forced convection, radiation etc.)
My problem is vertical vessel skirt which is as high as vessel, where high heat losses can be expected.
My skirt is a large, cylindrical skirt with large surface area.
how to...
