Electricity Consumption of Standby Devices and Impact of Daily Power Disconnection

Question

Hello ! For some time I have been tormented by the daily disconnection of electrical devices from the sockets. I ask myself - how much electricity is consumed at night by unused electrical devices, such as microwave, TV, set-top box, tower, etc. - that is, most devices remaining in stand-by mode...

elektor18 · Answer

Well, over the course of a year, it will certainly save a bit, but in my opinion it's not worth it because some of the devices will require re-setting. As for waiting after turning on the power, there is no need, you can turn it on right away without worrying.

Zygicm33 · Answer

It is worth disabling devices from standby at night, it is best to use special sockets with a time switch. They consume very small amounts, but they always consume something. This can save you some money per year. Do you want to wait a while before turning on the device after connecting it to the mains? I don't think there is any need. Regards

Brosper · Answer

Without exaggeration, the fact that one LED will not burn will not save the world. And as elector18 wrote, some devices will probably require re-setting. Well, it's not worth bothering about.

Hello.
I'll tell you how it looks in my place. The set consisting of LCD TV, receiver, TV SAT decoder and PS3 console consumes over 40W from the network. The desktop computer that I currently have, at rest, consumes about 15W from the network, although it happened with cheap and old power supplies that the consumption was 40-60W! So if you put everything together, it accumulates a bit. Disconnect? In my opinion, it's not worth it, because when you turn on the power, the devices get a little hard, for example by the phenomenon of electromagnetic induction.

TV devices most often fail when turned on, but some models can consume several watts on standby. The choice is yours, one case less beer a year or off )

Hello.
This used to bother me too, so I bought an electronic wattmeter.
After measurements, it turned out that I can save up to PLN 100 in a year, so I gave up.
As TRZY8 wrote "a case of beer less" a small loss and the TV set -> priceless.
Your choice.

MARCIN.SLASK · Answer

When measuring the electricity consumption of devices turned on in standby mode, I got the average (active power):
- receiver: 0.018kW/day,
- two mobile phone chargers: 0.003 kW/day,
- computer + LCD monitor: 0.092 kW/day.

Measurement made: Energy Logger 3500

michcio · Answer

Just out of curiosity... What is the counting threshold for an inductive meter? Isn't it by chance with 20W? What did you measure it with? A regular multimeter or a True RMS meter? Because electronics = a lot of reactive power.

zezuama · Answer

I measured with a wattmeter based on the ADE7755.

ajpier · Answer

Buddy Zezuam. Describe your devices in more detail, and in particular this old power supply draws 40-60W on standby every 40-60W.

Darrieus · Answer

Devices sold for some time (I won't make it up since when) can't stand-by consume more than 1W (the EU was dipping in it ...) so in about 40 days one device will charge 1kWh, if someone wants, let him count how much it's money.
The author of the topic asked if there could be a strip with a switch instead of removing the plugs, maybe and why not....

PS As we have older devices, you have to count 5-10W .... (per piece)

Romulus7874 · Answer

acc. readings of the electronic meter, consumption at idle, say - at night is about 40W. The receivers include: grid antenna power supply, two TVs and a sat tuner in standby, power supplies from the router, alarm and gate controller, and a turned off computer. So that a few zlotys are used for nothing. Some devices can be connected to strips, but e.g. pulling all the power supplies out of the sockets is almost pointless.

MiL999 · Answer

@lubamet - this is unfortunately not the case, an example is the Multimedia TV set-top box. On or off, it consumes at least 18W.

Darrieus · Answer

And what year of production?

MiL999 · Answer

2009 - is new but made so that the software loads from the network and is turned on even in standby mode. Probably to prevent the software from being deleted. Generally hopeless.

romoo · Answer

Nevertheless, the refrigerator, light bulb, iron average night power outages.

Darrieus · Answer

You could say that there is no standby since it is able to update itself. Hopelessness indeed.

zezuama · Answer

Buddy Ajpier. This wattmeter is nothing original, I built it based on the AVT-592 scheme and the only, so called, modification was the use of a different microprocessor. As for the power supplies, I will describe only the two that somehow stuck in my memory the most. Well, both are atx 250W codegens which I got once from a friend. The one that consumed 60w the next day after the measurement made a loud boom when switching on, and since I had a second identical power supply, I packed it into the computer and immediately checked it with a wattmeter. This one was 20W more economical, but it did not give me it's peace of mind, so I measured a 350w modecom at my brother's and immediately bought an identical model and now the power consumption oscillates around 12-15W. I'm not complaining

sebjaw · Answer

Hi.

I'm all for turning devices off. Special sockets with a built-in switch may be best for this purpose. Standard in many countries - a rarity here.

In general, it is not important whether one person can save a lot or a little in this way ... but what matters is how much a whole city or country can save in a whole year - if everyone had such sockets with a switch and used them ...

Not to mention the ecological aspect (reducing CO2 emissions into the atmosphere, etc...)

An example of such a FunCo socket:

Doesn't it look like an ordinary television n decoder? I have an n recorder and it has an external power supply like for a laptop, so I don't think it consumes less in standby because sometimes at night, even in standby mode, I can hear the hard drive turning on and they had something. . . As for the equipment at the desk, I made my life a little easier: I took the 12V molex power supply from the computer, my computer is connected directly to the network, but the speakers, laptop charger and monitor to the strip in which I put the relay and connected it to the 12V from the computer. After turning off the computer, this strip automatically cuts off the rest of my devices from the network. I'm still thinking about using such a relay to cut off the DVD power supply, but I need to measure whether the scart OUTPUT from the TV shows a high state after turning it on ...

It's best to turn it off unless you need to set the clock later. Each device in stand-by consumes electricity unnecessarily. Count how many devices you leave unused and permanently switched on (chargers, computers, printers, amplifiers, radios, tuners, TV sets, modems, etc.). Let each consume an average of, say, 5 W. Calculate for yourself how much wasted energy it is, not to mention what someone wrote earlier, i.e. CO2 emissions. Seemingly nothing on the scale of the whole apartment or going even further a city, country or continent, it's already nonsense MWh of energy used. In Poland, electricity is made of coal, in the west they have a little better. Surely that's more money saved per year than that case of beer. And certainly in stand-by it is not only the current needed to power the diode, as someone mentioned. You also turn off the car when you're not using it, and yet it uses MUCH less fuel when parked than when driving. With electrical devices, you use them for a few hours and most of the time they are on stand-by. In the end, it may turn out that most of the energy they took went into the whistle. And when it comes to inductive meters, as someone has already mentioned them, they actually need a little more current to start spinning, but once they start spinning, they will count every unnecessary charger.

Have you been told that CO2 emissions are harmful? Well, anyway, I support turning off the devices, but DON'T GET PARANOIA.

And how I think that all these savings are a lot.. y
Not that they are pointless, but how much we save, they will soon add an increase and we are back again.
The same thing happened with my mother-in-law's water. Big bills because 5 people registered and the woman lives alone. It was the idea of a wonderful water meter. Of course, the bills fell for the first year and everyone, on the advice of the mother-in-law, installed water meters in the block. And after a year, the compensation came because the sum of the water meters does not equal the state on the main water meter - someone is stealing on the side. The compensation came as if 5 people still lived in the apartment and there is no explanation that the woman spends more time with her children than at home and uses enough water to water the flowers on the balcony on hot days

Of course, the water meter is legalized and sealed, it is billed according to the water meter throughout the year, and at the end of the year they make an equalization

So, the more we save, the energy company will raise the price, including constant transmission, variable transmission, energy component, cable thickness, and whatever else they come up with to rip off our money because less consumption means less profit and people want more and more salaries.

Piteros Electricos · Answer

When it comes to saving electricity, you can set up a dual-tariff meter - the night tariff is half the price of the day one. but you have to lead a "nightlife" to make it profitable, because in a single-tariff meter you pay an average of 0.50 PLN per KWh, in a dual-tariff meter you pay an average of 0.60 PLN per day, and 0.30 PLN per KWh for a night tariff

CMS · Answer

Maybe I don't know something, but if I understood you correctly, did you connect the relay - coil to 12VDC? Doesn't that sound suspicious to your friend?

ajpier · Answer

And in the event of an anomaly in the network, the desktop computer will burn and disconnect the rest. In fact, security for a twelve-year-old, but whatever, the point is to make your life easier.

LuckyDj · Answer

I don't understand gentlemen.
What is to be heated or burned?
I had the same powered amplifier and equalizer, it annoyed me to turn everything on and off one by one. I turned off the computer, released the relay and everything went out. What's the problem?

You may as well turn off everything with the switch built into the strip, here it depends on whether the computer is working.

Maticool · Answer

A socket with a switch is an average idea in Polish small apartments, where most of the sockets are hidden deep behind the furniture. In addition, some do not even want to press the switch on the TV, let alone bend down to such a socket.

Pirosomack · Answer

I have a question for users.
I understand that connected to the socket, devices waiting for a signal from the remote control or having watches consume energy, but how would a turned off laptop or charger in contact not connected to any device consume energy. When they are turned off, the circuit is not closed, so no current should flow. Let someone with more knowledge on this issue chime in.

I would like to point out that in the case of some equipment, the relay with the controller will pay off longer than the device can withstand.

Greetings to believers in the greenhouse effect
