Our bangkaew loves going for walks and once outside the gate(one rai of land) on her leed she is fine, she also loves going for rides on the scooter, all depends how you raise them and their parentage. She will only allow my wife and myself inside our fenceline and to get close to her, she is very loving but the people we got her from were always able to go near her as well, also the vet is fine with her too, you just have to have those you want them to accept be around them a lot when they are puppies/young so they get to accept them but anyone coming into your land/yard needs to make sure they are locked up in their own area first. We have an 8 mtr by 4 mtr roofed and fenced area for our dogs and they stay in there apart from when we let them out to run etc a couple of times a day. Thais do not come anywhere near a bangkaew and when they see one they go the other way, their reputastion is enough to scare them off

You are the same guy who as (according a post many years ago) not have any problems to ask on this forum information what is a good way to poison dogs??

I think you should be banned life time for keeping dogs.....

First of all, (and after that check the other requirements):

Have the dog chipped, make sure the veterinarian who places the chip makes a certificate that he placed the chip.

(AFTER placing the chip have the dog vaccinated against Rabiës) even when the current vaccination is still valid. Then have a blood sample tested for a Rabiës titer test.

These first three steps are time consuming (at least three months) so when started this you have time to check for the other things you need to do.

Good luck.

From my earlier post: -

I suspect your RCD is right on the brink trip wise, possibly there's a switch-on surge that pushes it over the edge but running on inverter softens that or maybe lack of a N-E bond in the inverter just defeats the RCD for long enough.

 

The above is pure speculation based upon experience, but I really don't know exactly why you are seeing this. So, we just have to use the scatter-gun approach, eliminating the easy stuff first.

 

To actually measure the leakage current requires some specialist equipment (a low reading AC clamp ammeter).

 

You may find that simply swapping the RCD with another will solve the issue. The requirements for an RCD are that they must NOT trip at 50% of the rated current and that the MUST trip at 100% of the rated current. So, a "30mA" RCD could trip anywhere between 15mA and 30mA, a pretty big range.

 

By the way, you really shouldn't be running your inverter with no N-E bond (or at least an earthed neutral - but check the manual) as it defeats downstream RCDs.

 

Many, many years ago you told me that it is normal an inverter does not open a RCD, you explained with a story from your teacher, who touched (if I remember correct) a three phase power supply, connect through a separation transformer.

It is really many years back, but that made me still thinking it is normal my inverter does not let the RCD's trip.....

Regards.

Also, is your feed to the pond area underground? Isolate it where it emerges and test (maybe run a temporary above ground feed).

 

All cables are "in the air"

If the tripping RCB only feeds the pump, how does the float switch get its power?

If the float switch is one that the sealed contacts actually float in the tank, these can leak. 

If the float switch is on that tripping RCB, maybe disconnect the feed to it and see what happens.

I wrote: "the tripping circuit only feeds the fish pond"

There are more things in the pond. Like type floater switch (it is from the kind with two floating "things" When two are submersed the switch switches, and when two are free from the water the switch switches. The switch itself is above the water. When I disconnect all, so this switch, the pump, and an "Atomizer" the RCD still opens.

If it's isolated down to the pond the it should be "reasonably" easy.

 

Check everything is dry of course.

I've had submersible pumps leak and start tripping the RCD, the only fix then is a new pump I'm afraid.

 

Even when the pump is unplugged the RCD trips.

The position from the floating switch does not matter.

Last night heavy rain the whole night. The thing is still on...

But can you explain that when it trips, even very short running of my inverter can solve this for something like 24 hour?

Thanks, and regards!

@itsa

Thank you, and I hope you can solve your problem fast!

Maybe next time start your own topic??

Kind regards.

I have all circuits separated. On this circuit is only the fish pond.

And only this circuit trips 

Probably I should start a new topic? And let Itsari use this topic?

Kind regards, and thanks for help!!

It looks like Itsari took over my post..... I hope my post help him to solve his problem....

To answer some initial questions:

• In the past it worked OK.
• The problem started after heavy rain.
• So damp inside the box where the pump is connected can be an issue.
• Every circuit in my house is equipped with its own RCD. The main breaker does not have a RCD.
• I understand the RCD opens when it is dampy.
• I understand the RCD stays closed when I change the power supply from grid to my own inverter.
• I do not understand, and that was my question, when I run just a very short time on my own inverter,  (a few seconds is enough) the breaker stays closed (ON).
• We hire sometimes a very capable electrician (capable as far as I can judge) and he has also no clue.....

Best regards.

Hi all,

I have this strange issue. 

Our fish pond has pumps, pumps are connected to the power in what should be a water closed box, but with heavy rain the box is dampy inside. So when heavy rain often the RCD opens. No problem. I understand why this happens. The last few days the RCD also disconnected when there is no rain. Always in the late afternoon, or early evening. I still thought because some damp issues. 

When the pumps do not run the whole night, I am afraid my fish will not survive. So then I switched to our solar inverter. Then the RCD stays in (also normal I once learned, no common ground, or something like that)

Then in the morning back to the grid, and no problem till the next afternoon/evening.

This I all understand. 

But now the strange thing. 

I discovered that when the RCD opens, I am unable to close (It opens direct again) Then I power on the inverter, and the RCD stays closed. But.... When I then direct power off the inverter, and go back to the grid, the RCD stays closed (So all works fine) and it stays closed for the whole night. 

Like switching on the solar inverter resets something? 

Anyone an idea where to look?

Kind regards.

Great explanation!

Many thanks!

I gave up watching after the sound went away. Even with a head set it was impossible for me to follow.

 and the inverter should be one to be able to just plug it into the wallsocket.

 

So if I get this right I should have different inverters, one for the leveled panels and one for the ones pointed in another direction, right?

To my understanding plugging in an inverter in a wall outlet without doing any precautions can be very dangerous.  And my guess is in Thailand even more dangerous then in many other countries. But even Crossy does not warn now, so I start to doubt....

Imagine your inverter is supplying 16A (Maximum what Crossy advises) and the CB on that circuit is 20A. Then you are able to pull on every outlet on that circuit 36A, without a breaker will open. Even way more, before a 20A breaker will open at an certain overload.

But Crossy is better informed. In case I provide wrong information, please remove this post.

Handy-dandy metric conversion calculator (does pressure) here http://www.worldwidemetric.com/metcal.htm

NOTE Volume conversions are for US units.

8.5 kg/cm² is 121 PSI

13 kg/cm² is 185 PSI

These are working pressures, burst pressure will be significantly higher.

On this forum we have the rule no other languages then English, and Thai are allowed. Probably we also must introduce the rule "no imperial units allowed" It is very, very confusing. Imperial is not scientific, so also not used by NASA. Most metric countries do not accept technical specifications in imperial units. Countries who use Imperial units use for electrical units Metrical units. (I never heard heard about ¹/₂V DC)

Imperial units are very difficult to understand and to make calculations with. 
To cask to convert Bar to PSI is a stupid question.

In metrical system when I see a tank, without needing a calculater I can estimate the volume it can hold, the weight from the fluid  it can hold.

This is close to impossible when using Imperial units.

I think you make it way to complicated. A transfer switch will make your life much easier.  Exclude some circuits you do not want to feed know from your generator. You want to do many things manual that it is close to sure that once it will go wrong.
 

When you really want to DIY make an arrangment with contacters, in a way that when generator supplies power to the designated place, you will always disconnect the connection to the grid.

In case you overload your generator, I suppose it just stops delivering power. 

Good luck!

If you can't see it's wrong to treat wild animals like that...or any animal like that...then I suggest you take some time to step back and re evaluate your morals and heart. 

I am sorry,

I have no idea what is wrong with this. My morals are OK, and my heart is working good. Thank you for your concern!

One more time, the monkeys are not wild anymore, the parents are not wild, and the grandparents are not wild. I do not know exact what the definition from a "wild animal" is. All our domesticated animals once have been "wild animals" And we also know that some animals are very difficult to domesticate. Lions, Jaguars, are difficult, but sometimes very succesfull to domesticate. Most birds of prey are very easy to domesticate. Most swines, chickens are very easy to domesticate. 

Monkeys are also easy. Even stray dogs, even the wild ones, are easy to domesticate. 

On 3/7/2021 at 6:38 PM, jak2002003 said:

Really. So you are telling us that if your remove the monkey's chains from around their necks they will not run away? If you keep them in a cage and open the door they will just stay in there are not escape? 

 

How about if I fasten a chai around your neck for the rest of your life and not let you have any freedom.  That is no way to treat any wild animal and you should know in your heart that is wrong. 

Yes, that is exactly what I tell. 

They do not escape, and they even do not try or intend it. They stay at the same spot as when they are locked. Till we approach them. Then they will move away. So that is the moment we need to catch them.

The monkeys are not wild animals. They are bred in captivity (that is also required by Thai law) And also the parents from these monkeys must be bred. All is registered, monkeys have a chip, and there are regularly checks. Maybe an interesting read for you: https://www.firstschoolformonkeys.com/abused-monkeys/

I think most people are tight with a chain around their neck. And we know most people do also not escape. So not much difference.

So the only difference is they don't physically hit the monkeys. 

 

So you support .. 

 

A. Baby monkeys being taken from their mothers and family groups.

 

B. Wild monkeys being taken from the wild 

 

C. The monkey being kept on a short chain fastened for the rest of its life. 

 

Even the school report says they monkeys have to be tethered to stop them escaping.  So they can't be that happy if they want to run away.

 

 

The monkeys are kept tetherd as they are difficult to get. They will not escape. They do not try to escape.  They even stay mostly at the place they ususal live. Only problem with monkeys, you can not teach to approach you when you call them. 

We never said we need to keep them tethered to prevent them from escaping. That is your (complete wrong) imagination.

I have also a hot fill, but it seems ashing results are much better when you warm the water with detergent, and the clothes slowly. So fill with cold water, and warm this slowly...

I am not sure about the costs. Some people use for cleaning purposes scuba diving tanks. When they are full (200 Bar) you can clean many times your keybord. There are more advantages, no water, no oil in the air. Filling a scuba tank is quite cheap. 

I also kill algae with UV lamps. It works (The killing I mean) very well. But the live time from the lamps is very short. When the lamps last 4 weeks I am a happy person. Usual it is ten days. I changed now to 24 lamps from 8 Watt. Every 12 hours I switch from 12 lamps, to the other 12 . My pond has 40.000 liter. The time the water is in the filter area with the UV lamps is about 4 minutes. The UV lamps are installed between two polished SS sheets. Nearly daily I notice some lamps stopped working. Nearly every week I change the broken lamps. When they work, the result is good.

As poster does not even have a ground would strongly advise having protection for everything.

 

Have been using for since 1978 and have never had a trip cause food loss (yes somebody normally home) so believe this fear is a bit overstated as there are very few false trips (close lightning hits every few years perhaps). 

Where I live we have very ofthen lightning strikes close by, and very often ELCB's (or how ever they are called) do trip. Every circuit is secured with its own ELCB, and the strange thing is, they do not trip all, and when they trip it is nearly never the same one. It is random.

One other point to consider. A pump at my previous townhouse kept running often. Then continuously. Turns out there was a very small tank with a bladder attached to the pump. That bladder was filled with air, so it became ineffective. The house manager somehow bled the air out of that bladder, and it went back to operating normally.

There should be are in the bladder tank. Replacing the air for water will make the pump running very short cycles. 

I placed a big PVC tube, 10" in my water system as big "bladder" tank. When I close the valve to this tank, my pump is cycling about one time a minute with one tap full open. When the valve to this tank is open, cycling is reduced to 4 minutes.

My only problem is that my own made tank does not have a bladder, so air is solved quite fast in the water. WHen air is reduced in my tank, I notice this because my pump start to cycle much more. 

My conclusion, a bladder tank should have air, and not water.....
