really? I wonder what you do all day? some of my best friends are UK Networks employees and I can assure some of the posters on here who dont know ZS from ZE, who think its ok to draw fuses on DNO networks which are installed in DNOs customers properties to risk life, they know exactly what they are doing.
They are highly trained, highly qualified, highly experienced people
who work in some of the most dangerous situitations in some of the most appalling weather imaginable.
Not for them a 5 day wonder course, and a rubbing bashing career.
Its them who come to the rescue of customers who have had their supply
messed up by a deluded Part P.
I and many others lost one of our colleagues 2 years ago when a 132KV
transformer exploded, through no fault of his own.

Take my advice fella, leave it to the proessionals-the DNO

'the professionals' eh!
The other day I requested the DNO alter a loose pipe clamp on an incomming TN-S supply cable. Bloke eventually turned up after the customer spent a day on the phone and 'tightened it' with his screwdriver then left. All in under 3 minutes apparently.

Phoned EDF the other day got a girl in the call centre told her there was no earth on the property asked can you come and fix it.

Not their problem I was told!!!!

Hold on it's your earth that is broken... Not our problem told again.

Hold on then the earth has a high reading....yes sir we can deal with that.. do you have the reading....Yes Ze is infinity. No sir I need a reading!

Head wall ...wall head.

Go on then it a just above a million ohm's. Twenty minutes latter 2 EDF vans pull up. And sort out their broken underground earth by changing the supply to PME as their earth cable running under ground was broken.

Professionals.......... yes but thats once you get past the telephone operator.

Do instruments with a resolution of 0.01 Ohm display "infinity"?

"girl in the call centre"

Perhaps she knew more about maths than the average electrician?

Can they resolve values as low as 0.01 ohm .

The guys on the tools may well be professional but customer service is not and it's been like that for years. Can't speak for other DNO's but that's certainly the case with EDF.

PME

I know that a DNO worker in Chelmsford, Essex died tragically when resetting a HV protective device that kept tripping out. Don't envy anyone working in those dangerous areas, feel for the family left behind, especially as it wasn't there own fault

Dear PME,

If you had read my post, i think you will find that my critiscism was leveled at the people who answer the phones, not the people who actually do the work.
As mike jumper points out, and i am in EDF land as well, the problem is the people in the call centres who take the calls not the jointers etc.

Dont think for a moment that people on here dont have anything but the greatest respect for work that they do.
As i recall in the discussion about cutouts, i was not alone in the critisicm about the process, but where is your comments about them then?
As for 5 day wonder, well more like 20 years, but then again you know nothing about me, so keep you comments less personal in future.
99% on here are with you including me

According to 4.5 in GN3, to be adequate, yes Geoff

As to accuracy down to values of around 0.2 Ohm.....well......

Well the people at GN 3 need to read the BS EN 61557 series of standards - and they might try some of the manufacturers specifications too.

For example - one popular instrument, when operated on its 0.01 ohm range and reading a fiducial value of 0.25 ohms has a possible percentage operating error of 33% - representing an intrinsic error of 0.04 ohms - oh dear we are going to have trouble with our 0.2 ohms.

In fact they only claim compliance with BS EN 61557 for values > 0.3 ohms .

I guess if they can display it, then they can resolve it. Whether it's accurate is another matter! Apparently it's mostly not.

No disrespect to anyone at all, but to be honest some of the DIY jobs you get in domestic leads you to think that you can never overstate the obvious.... cannabis farms tapping off before the DNO fuses, bare earths used as lives.. all sorts... EDF changed the head in my house some time back, for some reason they left that twiddly bit of wire as the main earth... they obviously knew what they were doing...

Evening,
Does anybody know what was causing the tripping which ended up being the cause of such a tragic event.Was the tripping due to a fault in a house somewhere due to dodgy electrics.

The fault was on a 132kV grid transformer. The size of the fireball when the transformer failed prevented escape.

PME, I read that and I get it. Awful.

I draw fuses and I draw them to keep myself and my customers safe.

I can spend an hour on the phone to various people as mentioned already, and end up feeling a complete pratt, or I can switch off the loads and pull a DNO fuse with my pliers.

Every time I do it I know I am not supposed to. But I do.


Tell us more.
