Reducing the output by changing a resistor can give extremely long life (5 years and going strong) or buying the (impossible to get here) Philips Dubai lamps that have been Engineered for long life call running relatively low output.

That's all fine for the few that have skills to tear open their led lamps and adjust the current limit. The rest are left in the hands of lamps with limited life.

Dubai.

We have a terrible carbon footprint, how can we wash over the flak?

Throw a boat load of subsidy cash at Philips and ask them to go against all of their manufacturing rules to make us a super long life LED lamp just for us.

My Eve LED have been turned ON for many years already.

Does it help to keel LED on 24 hours to have them die slower ?

 

If the driving electronics survive, LED output will reduce over time depending on operating conditions.

The output reduction often goes unnoticed until above 30%+

Leaving the LED on 24/7 is a gamble. Stress from temperature change will be reduced but other components might have their life shortened.

Out of interest I checked search results (using the same search) for "Current Region" and then "UK" and came up with the same list of search results in each case, but note that I am using Firefox.

In all browsers, Google search looks for a region cookie which normally follows local IP address unless changed by the user.

Search for TV Show with region set to Thailand then change the region to UK and search for TV Show again. Note the different search results.

Region setting for Google searches is lost when cookies are cleared which is why it annoys so many people. IP change via VPN is the best way to ensure consistent region results.

Bidirectional metering using current transformer.

To be sure of correct current and voltage phase calculation, the current transformer must have the phase cable passing through the coil and the coil connections arranged to the meter manufacturers diagram.

I think that happens when you have been inactive on the forum for a while and it does a browser check.

It get it sometimes and click confirm to let it do it and everything is ok after it finishes.

 

Its an annoying problem that has appeared after recent introduction of the Cloudflare pre check and should be corrected. The problem is immediate after the Cloudflare check redirects visitors to the home page. There is no time period.

Not being able to use basic browser navigation back to a home page without a confirm form resubmission is ridiculous.

If the problem is on the tech support to-do list is should be a high priority item.

The short term fix is to hit the sites forum home link after landing on the home page. This takes the browser down a level away from the annoying form submit.

I know. But do you understand why the max value is 3 times the base value? 5/15 and 15/45. I couldn't find an explanation. At 30/100 it is almost the same. And it still doesn't make any sense to me that they call it a 5 or 15 Ampere connection if it is good for much more. Perhaps it is really only TiT... 

I explained why they have these wide apart values on the meter. Depending on class, Ib determines at which point the meter starts registering.
This value will be much lower for a meter with a low Ib like 5/15.

Calling the connection 5/15 indicates the max accuracy point and value used to set start point (Is)

For electronic metering one size often fits all

Clue - Its advantageous to match the meter accuracy range with the users max demand.

There is for sure a reason for the 15/45 and also for the new 5/100 on the electronic meters.

Electricity meter 15/45 Class ? 

Ib 15A Imax 45A

Imax is the point up to where the meter should remain accurate.

Depending on class a percentage of value Ib will determine at what current the meter starts registering. Eg 40mA

There is a transformer about 300mt up the road with 2 phases coming in (3 wires total...(hope I got my phases correct this time!!) coming in). The supply then branches out to the tapioca and vegetable plantations with about 6km of wiring. Only supplying power to water pumps and the odd light after our Bahn supply.

Nuisance tripping from varying grid voltage.

Most certified inverters have grid parameters set to meet the supply authority spec which can be quite strict with the re-connection after fault voltages.

I am sure the Thai authority have provided a voltage spec to Huawei but doubt if it has considered the many areas on its grid suffering from large voltage swings.

I believe most Huawei inverters provide some adjustment to the upper and lower cut off levels including their timers.

This would likely require a special installer code and application to access low level settings. 

@Pilotman

I see my posts have received the predicable sad flags. Very professional.

I get the feeling that like me you of the Microsoft Sim academy.

That my friend doesn't make any sense. Glass cockpits and computerisation help to reduce pilot work load, they do not replace basic aviation and piloting  skills  and knowledge.  

You forgot human error, read my first post.

Didn't  Sully provide the definitive example of this obvious fact?  All the computers in the world could not have saved that aircraft and it occupants, basic flying skill  and professionalism did that. 

Not everyone has the same level of skill. Flight 1549 was lucky to be carrying a high level.

Computers aid in aircraft is not about helping the rare incident like complete engine failure.

Not sure even now if it was a step forward or not, as it seemed to me that Boeing and technology was trying to move me ever further away from actually flying the jet. 

With so many air crashes caused by human error its nice to know there are powerful computers watching over the unpredictable organic matter.

Its also nice to know that systems like OFDM are monitoring pilots and looking for trends that need to be addressed.

it's not on the single-line that I can see (our equivalent is a simple clamp-on current transformer on the incoming supply).

But what throws a spanner in the works is :-

QUOTE - We had to run a second phase from the grid meter as we burnt the supply cable out. So we have 2 phases coming into the bahn.

Wiring around the Schneider load center is interesting.

I will hold back any comments about solar production until the OP has all ducks in a row.

If its a one off, how about 3D printing?

The printer would need to be good enough to produce suitable finish and precision. Then there's the problem of scanning and measuring the original excluding any damage.

Yes it is the selector plate from a Hayward filter valve.

 

Could you inquire with your brother where he got it modified?

The worn top of the spindle was modified to stop it slipping in its operating lever. Not sure of the valve brand.

The work was carried out at by a small engineering shop in the Naklua area. Location - 12.970257, 100.909292

Best take some translation help to explain the problem and understand any fix suggested.

That looks like the pool valve part my brother was asking me to locate. He ended having the whole assembly modified somewhere in Pattaya.

3M and maybe other brands have heat shrink self sealing splice kits which I believe can be used to extend the short tail provided on some submersible pumps. Quite possibly available in Thailand at specialist pump services. 

Thinking back I remember contractors making waterproof joints by injecting silicone sealant into heat shrink sleeve. This prevented any capillary action within the core.
 

Example.

You need to define a pattern or patterns of interest. Patterns can be simple repeat expressions or a complex mix of variables. The Chinese add all kinds of nonsense to the mix.

Lottery number generators produce patterns which is why those taking the probability math's too seriously often end up medicated and strapped to a bed.

My brother uses Kasetsart University Animal Clinic Bangkok for anything serious with his dogs. His local vets around Pattaya are not equipped for anything beyond basic diagnosis.

Thats true as the Thai Chinese connections collect and send many of the used cells here in Shenzhen for a re-wrap. If there is easy cash in a recycle, Thailand leaves no stone unturned.

as it seems to be  National obsession to open a coffee shop every 500 metres. 

That's all down to what Mia Noi prefers her master to fund with Coffee Shop top of the list closely followed by Hair Salon.

The used 18650 gold rush has slowed. YouTube drama queens have had their revenue and E bay sellers jacked up the price to suit popularity.

I guess spending time testing and sticking together hundreds of used cells has its therapeutic benefits for some.

Lifepo4 can be under $80/kWh and gathering pace in the DIY solar market.
