Power surge protector

| 1 | Do I need a power surge protector for the power supply to my Smart TV (Panasonic). A DVD recorder (Panasonic) is also connected to the same power point via a strip style multi plug. mariner26 - 2021-07-26 15:38:00 |
| 2 | depends on what you think you want it for These things do only about 10% of what the claim is they do. A pure sinwave ups would be of more use , but almost any ups are squarwave cheap and nasty trash. Edited by intrade at 3:50 pm, Mon 26 Jul intrade - 2021-07-26 15:49:00 |
| 3 | I bet a salesman / sales person at Noel Leeming or Harvey Norman has tried to sell you one along with a new appliance !! It is their standard sales pitch to frighten you into buying one and therefore adding a little bit of extra sales commission to the sale. onl_148 - 2021-07-26 16:24:00 |
| 4 | I have seen computers damaged by power surges. More particularly during storms. Lightening. nice_lady - 2021-07-26 17:03:00 |
| 5 | i've repaired a few houses and repaired/replaced a fair few appliances that have been hit with lightning. its a little bit more common than people let on. highly recommend surge protector on the mains fuse board as well as by sensitive appliances. multi board or plug in protectors are common enough. also if you have anything connected to phone lines put a phone line protector on. tweake - 2021-07-26 18:01:00 |
| 6 | OK then. mariner26 - 2021-07-27 08:37:00 |
| 7 | It's not protection for power cuts as such - it's for when the power comes back on - it can 'spike'. It can also do this on occasion anyway but the odds of damage are very slim when a 'surge' happens or you'd hear about it in the news much more often. nice_lady - 2021-07-27 10:12:00 |
| 8 | Weve got 2 ,1 For TV and 1 for computer.I dont know if they "work: but weve had plenty of power cuts and lightning none of which have affected any of our appliances.For the cost of them its worthwhile as insurance just like car and household insurance but much cheaper.Individual choice.! gazzat22 - 2021-07-27 10:21:00 |
| 9 | Should you buy a unit or not buy one if you want but dont relie on it to do anything if lightning strikes you better unplug everything possible during lightning strikes you can count from flash to bang is just under 1km per counting one two .... anything under 10 i start unplugging stuff especially if it counts get shorter.

When you see lightning start counting untill you hear the thunder. 3 seconds means 1 Km distance from the lightning. So if you see a flash and count 6 seconds till you hear the thunder rolling then it was about 2Km away. Edited by nice_lady at 12:16 pm, Tue 27 Jul nice_lady - 2021-07-27 12:15:00 |
| 12 | #11 my one is more easy to remember and it can come close real quick its why i use the 10. if you have to get a calculator out to see how close it is then its probably to late already. intrade - 2021-07-27 12:20:00 |
| 13 | another thing ADsl copper is way worse then fiber Fiber wont send the lightning in to your computer . But copper you better unplug from the wall . I have a spark arrestor from my mate that they used at telecom The adsl seems to travel thru it ok But i still unplug everything if i hear lightning close by as Lightning will overcome everything on a direct hit. Keep cable 10 cm or more away from sockets. Edited by intrade at 12:33 pm, Tue 27 Jul intrade - 2021-07-27 12:26:00 |
| 14 | If there is a power outage I usually turn off most appliances to avoid power spikes later. I may have plugged them into my emergency power supply anyway. trade4us2 - 2021-07-27 13:12:00 |
| 15 | You shouldn't have such things in your ADSL line. spyware - 2021-07-27 13:17:00 |
| 16 | ADSL is definitely vulnerable to lightning strikes on occasion. As for the distance from lightning intrade, Hubby refuels aircraft. So in a lightening situation the refuel guys have to be very aware of how close the lightning is. So counting the time between the lightning and the thunder gives them a good indication of distance. And yeah if it gets closer they get very paranoid lol, and they can refuse to refuel. And no one can override them on that. nice_lady - 2021-07-27 13:31:00 |
| 17 | I lived rural and had a Jaycar one and Belkin one. The Jaycar one fed the computer modem and had the phone line through it. I replaced it a couple of times after lightning strikes. No other damage. AMI paid for the replacement both times with no excess as the first strike I had cost them over a grand and me $250. I eventually had chorus fit some decent surge protection and earthing on the outside of the house. Never had an issue after that Edited by macman26 at 1:33 pm, Tue 27 Jul macman26 - 2021-07-27 13:31:00 |

| 21 | its a bit like insurance - you either want it or dont but when the time comes you wished you had it when looking at a surge guard look at the joules rating - higher the better https://www.pbtech.co.nz/product/SURBEL2740632/Belkin-BSV804 trade_menow - 2021-07-27 15:20:00 |

Can't imagine it being good for ADSL at all, worst idea ever in all seriousness. I suppose you were only used to dialup speeds so performance didn't matter. Edited by spyware at 3:37 pm, Tue 27 Jul spyware - 2021-07-27 15:35:00 |
| 23 | If you were anywhere near dial up speeds on today's internet it would be a major fail. nice_lady - 2021-07-27 15:49:00 |
| 24 | Only the most expensive & robust surge protectors will protect your appliances from a direct lightening strike. BUT mrfxit - 2021-07-27 15:58:00 |

| 28 | ADSL works best over a "perfect" transmission line, cat6 from ETP to outlet. 4 km from cabinet would be what I call outside the use case anyway so imagine it would be slow, certainly no faster than 3 Mbps down surely? Edited by spyware at 5:01 pm, Tue 27 Jul spyware - 2021-07-27 16:58:00 |

| 32 | I used to make isolation transformers for phone lines, in case 33KV lines fell on them. trade4us2 - 2021-07-29 10:43:00 |
| 33 | Would not the isolation transformer pass the voltage? I guess the current would be limited. tygertung - 2021-07-29 10:48:00 |
| 34 | I made 12 transformers before one of them worked and isolated 33kV. trade4us2 - 2021-07-29 13:45:00 |
