I need to monitor up down status of electrical fence that operates at 8kv. Can somebody please tell me if this is possible with Arduino? Also let me know necessary hardware and other information if this is possible.

Does the controller have a neon light that flashes or does it "click" ?

As I mentioned in your other post monitor the current on the primary side. You may be able to do it with a resistor depending on the current draw. If it does not pulse the current it is not working and you can indirectly test the battery this way if it uses one. As the battery discharges the current will also decrease.

No lights flashes and no clicks. (I am not too sure about this as fence is not implemented yet). Terminal voltage is 8kv when the fence is broken or open circuit. It drops to 7kv when the fence circuit is closed or in healthy condition. (In my imagination)

I doubt anyone here can convert your imagination to 3d.

So, then, you do not live in the United states and you country has no laws relating to electric fences or relating to safety of electrical wiring.

Yes, you can measure KV.
One popular way is by using a voltage divider. A voltage divider of resistors can be placed and properly wired up and insulated would do the trick.
I'd get 1% resistors and actually measure their values for use in calculations instead of using the stated values.
You can use this voltage divider calculator to find the resistance you'll require.
Put in 10000 for source.
I started with 10K for R1
5V for output.
Now you can play around with the number till you get something you can work with.

You just imagining those numbers? Or are they from a real world appliance? If it's the first, you're just wasting our time. If it's the second, do post a link to the specific appliance.
Normally the way to check whether an electric fence is active would be to check whether the device powering it is on or not...
You need to know how the fence works - I’d *expect the output has a high impedance so people don’t get killed .
A resistor divider won’t therefore work and is not sensible anyway for this voltage .
Just check the power working the fence controller is ok , or use one of the other low tension side suggestions , can’t see anything else working
- hope
Link doesn't work.

And now you have removed the post I just replied to. That is not very nice. Perhaps you should try another line of work.
Thank you all for the answers. Fence energizer information is available in this Link .Please look at page 3, 12v energizers.
Important parameters are
Input such as 2.1/4.5 J
Output max 1.8/4.0 J
Max 8000v
500 Ohms 4800v
Fence length each

What is missing is the ordering information and the importing information as to where their use is legal. Don't see and UL or other safety conforming labels.

Get a dozen 10k fesistods.
And a dozen 100k
Make 2 strings
Connect the 100k string
Accross the fence
Connect the 10k string from negative to the first resistor.
Use your multimeter to measure voltage.
Let us know what you were able to read

I was going to suggest ceramic capacitors in series with a resistor on the bottom of the stack. BUT! None of these will work when the moisture condenses on them at night.
8KV will arc over resistors or capacitors when wet.

Come to think of it: don't electric fences typically produce pulses of high voltage, rather than having a constant voltage applied to the wires?

You are thinking of countries with such laws for human protection. The OP has referenced the catalog of devices that apply to other countries.
