Special K Posted April 23, 2024 Posted April 23, 2024 (edited) Just checking if this is considered normal? I picked up a Thor PS10 after having some concerns with the power supply here and it seems to be sitting at 300 give or take. Edited April 23, 2024 by Special K
Quark Posted April 23, 2024 Posted April 23, 2024 No, that is way out of spec - AU is officially 230V +/- 10% (was initially -6% to +10% when first switched from 240V). Call your network provider urgently - if it's really 300V mains, there may be a real fire risk. If you have solar panels try isolating them and see if the voltage drops. 4
Special K Posted April 23, 2024 Author Posted April 23, 2024 Thanks Quark. No solar panels here however I do live in a block of units. So high density.
Kaynin Posted April 23, 2024 Posted April 23, 2024 I've been monitoring by input voltage for three days now and my highest reading is 245.8, so 300 is huge. 2
aechmea Posted April 23, 2024 Posted April 23, 2024 Definitely a serious problem at 300V. Thinking out aloud; is the Thor working correctly? 3
Special K Posted April 23, 2024 Author Posted April 23, 2024 Yeah ok. Going to contact the provider asap.
Steff Posted April 23, 2024 Posted April 23, 2024 (edited) 12 minutes ago, Special K said: Yeah ok. Going to contact the provider asap. The Thor PS10 might also produce a bit of fan noise if it is regulating down from 300 to 240. Bit odd that the Load/Amps (ampere) is showing 0.0 - are you not currently running the Luxman? 300...yikes For comparison...from two minutes ago... Edited April 23, 2024 by Steff 1
Guest Posted April 23, 2024 Posted April 23, 2024 Are you sure the unit is working correctly? If so, I'd be switching everything off until of got the issue looked at!
Special K Posted April 23, 2024 Author Posted April 23, 2024 I was going to test it first to make sure it was ok as I just got it. This is an older unit, Not sure if has a fan... I have now plugged a Sansui 6500 in and that has not changed any of the readings.

I also moved it around to two different locations in the home and got the same results. Will be taking it over to a Neighbours to have a look at and test there as well.

Steff Posted April 23, 2024 Posted April 23, 2024 (edited) Is there an easy & safe way to measure voltage at the power socket @andyr ? Edited April 23, 2024 by Steff 1
Steff Posted April 23, 2024 Posted April 23, 2024 (edited) redundant, already answered. Edited April 23, 2024 by Steff 1
muon* Posted April 23, 2024 Posted April 23, 2024 (edited) These can tell you what is being output from the wall socket. https://www.bunnings.com.au/arlec-energy-cost-electrical-meter_p4410270 300vac is crazy, highest I have seen any one report is in the 260's. Edited April 23, 2024 by muon* 2 1

Thanks Ian, Once I have tested it at a Neighbours place I may have a further look at it. Appreciate it. 1

There are two ways that I know of, Steff (that are safe - although some folk here would say that because I am not a licenced electrician ... me doing #1 cannot be safe): stick the prongs on the ends of your meter leads into the '/' and '\' slots in your power point (with the meter set to 'AC volts'. use a 'Watts Clever' device - I think I bought mine from Jaycar. This is a very useful device because it can also read how many watts are being drawn by the device plugged into it. (The device linked to by Ian appears to be similar.)

Looking at the specs on the Bunnings site: ... this Arlec one appears to provide the same features as my 'Watts Clever' unit. I suggest you should look on-line before going there - just to make sure they have them in stock. 1 1
Guest Posted April 23, 2024 Posted April 23, 2024 (edited) Jaycar have quite cheap voltage / amp meters. I use one of these in my listening room to keep an eye on things -https://www.jaycar.com.au/mains-power-meter/p/MS6115 Edited April 23, 2024 by Deepthought
muon* Posted April 23, 2024 Posted April 23, 2024 Ah yes, the Jaycar one is cheaper. I got my Altec one when they were only 25 bucks.
Kaynin Posted April 23, 2024 Posted April 23, 2024 Yeah the $20 version at Jaycar will do the job. Very handy to have to see if voltage is causing any issues. 1
Addicted to music Posted April 23, 2024 Posted April 23, 2024 I would not muck around, report it immediately with the picture you just posted to the supplier. At 300VAC has the potential to cook components. Forget going to a neighbours or anyone in the area because they will be on the same supply line, especially if its in an apartment block. With smart meters they will be able to determined on the spot via remote monitoring and tell you exactly whats going on. In the meantime leave expensive gear disconnected until they confirmed its within acceptable levels. When they do come, they will be asking the question has anything failed, dont say "no" say its under investigation. 8 hours ago, Special K said: No solar panels here however I do live in a block of units. So high density. Biggest false assumption, solar PV pushing grid voltage high is rare, and if it was the case there would be something seriously wrong with the grid. in my case, high mains voltage was occuring at night and not during the day, @263VAC they took all day to replaced something in the street to get it back to 230-240. 1

Seems like my neighbor had the same reading. He did a bit more and power cycled a few plugs and even the mains at home. Same results. I called the provider and they said to check the house by a licensed electrician to ensure there was nothing wrong with the house wiring. I will head down to Jaycar and pick up one of those gadgets to test it just in case and even take the Thor to another destination away from home to test it to make sure it is not the actual unit itself. All this on the assumption that the unit is working well and as it should. Edited April 23, 2024 by Special K

Worth calling Thor to enquire whether the display panel board can be faulty on older units. Typically there would be some little variation of +-1 volt during the day, or at least after the decimal point. If the display shows 300v without change in various locations we can reasonably infer that the display isn't working properly. Edited April 23, 2024 by Steff 2
