I have no idea which one is for the solar panels

So I will have to wait until Monday when the electrician arrives to turn them off

Oh and by the way
I just remembered I bought one of these because I thought it could measure dips and surges
It was a desperate attempt to find the problem

However I don't really know how to set it up

Nought to do with your problem, and probably bottom of your list of things to do, did the electrician say anything about the Wylex mcb in an Eaton CU?

 

[Richard Burns]

The switch labelled solar PV is for the solar PV, nearby you should find an instruction label that tells you how to turn off the solar PV, there should be a local isolator switch labelled AC isolator and another one labelled DC isolator (this may be in the loft or near your inverter), switch off the AC isolator and then the DC isolator, switch off the solar PV circuit breaker.

These are simple meters that can tell you how much power you are using at the current time and how much power you have used over a period of time, however it will not indicate anything, at time or provide historical data, about the state of the power supply.

I can see the end switch says solar PV
I'm not sure about AC isolator or DC isolator. Is it that other box with the big red round thing in my pic

It is prolly best to wait until Monday when the electrician comes

Ah ok
No use then
Perhaps I will sell it

Mmmm I'm clueless what the heck does that all mean?
Anyway I will add it to my list to ask him when he comes on monday

Its a minor issue, but you not should mix different manufacturers products in a CU, unless they say they are compatible. Add it to the list.

It ok to test these theories

Theories they are indeed, and with or without theories or headscratching or doing nothing at all-you will still have a blown computer. So theories are not hurting or adding to your problems.
Power analysis is a way of establishing some facts. Maybe I am wrong fully accepted and I do offer this very tentatively, but at least you are out of the realm of theory and into facts. What would it hurt to try it, well apart from your bank balance. At least if you turn off the PV you should be able to find out if it is a contributive factor without power analysis.
Maybe your landlord would put something toward power quality analysis monitoring?
I think I would be looking into a Harmonics filter for single phase. The energenie power meter would in no wise give power quality analysis. A meter for this type of work costs upwards of £1500. There are companies that specialise in this. However it is not cheap. And finally it may not be the answer. I promise I wont talk about this again.

I have added it to the list to ask the electrician on Monday
Thanks

There is the list so far
I'm hoping he doesn't think I'm some sort of smart Alec or a crazy dudess

Lol

 

[The Ghost]

Not too sure about the last one....MCB! first line

 

[DPG]

I'm not sure who's taking the mick here now Daz

 

[Midwest]

Square peg in a round hole. If Eaton say a Wylex mcb can be fitted in one of their CU's, then that's fine. I'll doubt they would.

 

[The Ghost]

Bit confused there Midwest no oblique reference to your correct I.D. of mixed MCBs' its just the beachlover wrote MBC instead of MCB in first line, the first part was in reference to the last point in Beachlovers' list of points to bring up

 

[DPG]

Nobody has asked what 'signal phase' is yet either. Daz

Apologies

Apologies

Lol
I can't even blame the iPhone that time single phase
I scrubbing it out and writing a hundred lines
I must spell single I must spell single

Should I add anything else to the list ?
Perhaps I should ask him to PAT test the freezer we have in the shed?
It's the only appliance that is not new
. Brought it with me from the previous property. The property were computers did not blow up !!!

If I put my computer on the floor rather than on the computer shelf will it be grounded?

Ha, ha very droll! To understand ground circulating currents you have to understand the relationship between capacitance, inductance, voltage and currents in a computer system. Circulating currents can cause problems when output currents cause a difference between the actual output voltage and the feedback voltage as well as when the output ground currents move the power supply's analog ground off its true ground. They also cause problems when the output current in the supply and ground rails interfere with the delivery of an accurate voltage to the system and when the circulating currents are in loops which then radiate excessive electromagnetic interference into the system causing it to fail. Thinking about it, the only way to destroy this many computers with ground circulating currents, is by corrupting their bios chipsets. Are you sure you are not loading some computer virus onto your systems?

 

[DPG]

Computer viruses do not destroy electrolytic capacitors! Daz

You never seen The Matrix; red pill or blue pill?

My eyes are bleeding
Wtf does all that mean? :mkungfu:
Whoozzzze something flew over my head

 

[beachlover]

Well I have to agree with Daz
I don't have a computer virus because quite simply .... I don't have a damn computer

 

[beachlover]

Mama always told me not to take pills from strangers
Just sayin

 

[DPG]

I think I'm out of this one now. Been quite entertaining though! Thanks Daz

Look I'm sure you already realise and are just playing along, but to save you embarrassment just in case - don't ask about the final thing on your list, just look at what the first letters of the words spell !

Well there is one breaker marked Solar PV that could be a clue...
But my gut feel is an issue via the HDMI or DVI cable. What's the monitor connected to the computer.

Benq monitor bought new in 2015.
It was happening before on my old Asus monitor
I had a new motherboard GPU ram and PSU replaced in November this year. I decided to rule out the monitor by using the computer via my TV with brand new HDMI cables to rule out the old cable.
I also bought new mouse and keyboard to rule out any fault on the USB
I made sure I used nothing else.
Within a week it happened again and the GPU failed

 

[Pat H]

The GPU isn't the most sensitive device in the computer. CPU RAM and more are on the motherboard before a plug in card.
To blow things on a plug in GPU card or GPU motherboard I'd be looking at what connects via the monitor.
But again as I said before a UPS tgat connects to the mains and then to monitor and computer are a must.

 

[beachlover]

The electrician has been
I asked him the questions you helped me compile
1) he said Wyler McNeil in Easton cu is ok and is now passable by the power law peeps who govern electrician

2) he has turned of the solar panels and disconnected from the board

3) he looked puzzled when I said about quality analysis monitoring but he said that is what SSE have done

4&5) he said that was collage lectures stuff and has little use practically - his words not mine

7) I forgot what he said about TN-S or TN-C but he did say the house has had a rewire in 2008 or later because he says the wires have the new colours

8) he PAT tested the freezer and said it passed. However he said we should have used shielded cable to run it from the house to the shed.

9) he asked if the person who recommended an IDIOT Tests was for real ..... bbbwwwwhhhhaaaaaa

He voltage tested the board and sockets and said they were stable at 230 v and this was lower because of a v-phase something or other and a voltage optimiser.

He also put on a brand new surge protest socket on the one where I saw sparks coming from

Nothing more to be done regard the electrics I guess?
Just have to wait and see if the next computer lives or dies.

I'm thanking you all most dearly for all your help advice and brain power.

Wishing you all happy holidays
