3 phase loading question

[GLENNSPARK]

Cock ups... wow, where to begin....

Installing a single phase board in a factory where most of the machines were 3 phase.
Running a huge bundle of cat5e cables in the same trunking as the supplies to the office ring circuits (for about 25M)
Installing a 3 phase SWA and isolator in a garage, and telling the customer to order a 3 phase oven... then I turn up to connect the oven and its only single phase at the incoming.
Frying the entire AV system in a house by fiddling around with things he doesn't understand behind a AV distribution system... and accidentally switching the voltage to 110v (how the hell he did that I don't know).

... just a few things make me worry

If your been payed your wage then ok as non of this is on your shoulders but as others have said look for another job... you seem the brightest in the whole company yet your only have a few yrs experience which worries me to the competence of your work colleagues.

I am putting way more hours than I am paid to sort out all sorts of messes they leave.
I just can't do work to their shoddy quality.
No - its not really my problem, its theirs.... but if I am installing it... I want it right.
I have NO IDEA how they ever pass their Niceic inspections.
Only been with them for 4 months... and not many more hopefully

listen...
i used to work for this fella and he was one of the biggest emptyheads goin...

no i mean it...this guy thought RCDs detected overcurrent
total spacker...the things he did & came out with...i used to despair of it..i really did...

These are one of things that you will eventually learn grasshopper
Its the individual that matters,its not the parasite that preys on him

Tony , what a top site . That one has gone straight on my favorites bar ! unk:

At least one person appreciated it. That’s OK by me.

In the future that needle is going to swing further to the left. It may go below legal limits but it will never get to “total shutdown”.

Selective load shedding is in place and has been for several years. A plant I worked on could at a signal from UKPN shed 16MW of load within 20 minutes. More with advance notice.

If it's 15,000KW let me know when you switch it on.

I'll watch it on this Dynamic Demand

Cool site tony will take a proper look later

 

[Knobhead]

I think our OP switch the heaters on this morning at 07:30 never seen Dynamic Demand so low before. 49.85 Hz.

As an idea, when you’re late for work “the alarm clock was late going off”, blame it on the grid frequency slowing down!
Somehow I don’t think it will wash as an excuse.

tony introduced me to this dynamic loading website a few weeks back when him and I were on the phone...
so it was a good little experiment when phil davies came round last weekend for me to get my power quality analyzer out stick it on frequency and check it up against the website...
on the nail...

 

[Silly Sausage]

It does say you can measure the frequency from any socket in the country.
Has anyone seen this site...well here you go

U.K. National Grid status

Or get yerself one of these. Ex power station control room mid 1960s., changed one duff valve and a leaky capacitor and up it came within 0.01 Hz of my bench FG. Trouble is, if you want to wake up in the morning knowing whether your clock is running at the right speed, you've got to be able to sleep through the funny little noises it makes - the pointer is driven by a servomotor so it whirrs and hums all the time as the frequency changes. You also need a strong wall to put it on! Note the red marks on the dial - load shed is at 48.50Hz and island mode on the 132kV at 47.6.

Flicking back through the thread, the reference to the current being wrong 'because the OP hadn't built in a factor of sqrt(3)' - he had, you just didn't see him do it. He used the line current but the L-N voltage, which includes the division by sqrt(3). Saves space on the envelope.

Excellent! That's not your average car-boot sale find! Daz
