Failure LED On in Electricity Meter: Short Circuit Sign? Energy Consumption & Expert Opinion

Question

Hello I have a question whether the glowing failure LED in the electricity meter may be a sign of a short circuit in the building's electrical system itself. The energy guy came and said he checked the meter and it was OK - and the LED was on. He said that he thought the consumption was very...

Failure light means that someone has tampered with magnets on the meter. Inflated indications the same. :? Definitely not.

Hence the great popularity of neodymium magnets on Allehehe. It's good that you got a guy who did not pursue the topic, because it could end up badly ...

On the other hand, the lighting of the 'failure' led on the meter may mean that one phase is missing. You may not notice this during normal operation if you have sockets and lighting on the other two (which are present). I have phases divided into rooms and when one of them goes out, it is usually the one in my room and studio. And the other rooms are supplied with energy

So, I have a question whether a lightning strike (about 2 weeks before noticing the diode has collapsed in the area so that my satellite decoder burned down, and even televisions and computers at my neighbors) could be the reason for this error?

Added after 4 [minutes]:

What if I found a guy cool, I don't know - I'm not at home and he came to check it today (I reported this problem to ZE) and I'm at work.
the guy said he would have to replace the meter and the one that is sent to the forensic examination is due next week to replace it.

When it comes to magnets, no one was up to anything with them - it is a single family house and I think I know what I was doing

If you haven't magnetized anything, the so-called the forensic opinion will probably show that the meter was damaged by lightning. The meter belongs to ZE, so they should replace it on their own, but you should not bear any costs associated with it. About three years ago they exchanged with me, because the old one was about to end They came, turned the electricity off, replaced, sealed, turned on the electricity, went. They got a cake and coffee

ok.thanks just to be sure, because a few weeks ago I was doing a renovation and I was wondering that maybe if I drilled something, I drilled a cable somewhere and maybe that's why there is a failure on the meters (I do not remember anything more than this lightning and renovation which could cause a problem) - this diode and the faster (in my favor) counter should not be due to a short circuit inside the building?

bestboy21 · Answer

There are contractors inside which, after detecting the magnetic field, short-circuit the control circuit with the fuse, which causes it to burn and causes the failure to glow.
This lightning could have caused it, since your decoder burned down, after the expertise, if they do not detect the magnetization of the meter, they will not accuse you of anything, but these inflated indications are definitely not a matter of lightning.

A meter with a failure indicator has a rather specific operating principle.
This indicator lamp is used to signal any unauthorized manipulations with the meter.
As the previous speakers wrote earlier:

the action of an external magnetic field;
an attempt to withdraw the counter;

The only option is to report to the Power Plant that this light is on. The meter can be replaced, and if you want to wait for the legalization of the one you have, you will not have electricity for a few days - the meter is for removal.
And unfortunately, the court procedure is now initiated because there is a suspicion of theft of electricity. This indicator lamp does not indicate anything else.
The discharge could damage the counter.

However, I know cases when the control was triggered, for example:
a mobile phone on the meter;
with a car-type vacuum cleaner - a small portable one - a lady was vacuuming the walls and she ran too close to the meter.

My friend, I also have a counter with a failure signaling diode, but for me it only lights up in the absence of a phase, but it never lit when I had a short circuit and when the fuses worked, the guy from the power plant did not check the pre-meter protections, maybe it worked causing disconnection of one phase and therefore the diode in the meter is lit.

The FAILURE diode is to signal the damage of the meter and not the damage in the installation. It's a pity you didn't enter the meter type. If it is an inductive meter, e.g. C 52z, the FAILURE diode may turn on e.g. after changing the phase sequence in the power supply. You don't even need to know about it. The repair of the power grid may have happened outside of your territory, and although it shouldn't happen, it does not always happen in life. And why does the meter activate failures at such a moment? Well, because sometimes in induction meters (of course three-phase) when there is no proper phase sequence, the dial does not stop in the so-called brake point and may rotate slowly even after the post-stop fuses are turned off. You can check it at your place. The brake point is a black or red line on the dial. Before turning it off, place it more or less in the middle of the window and see what happens.
