Part 2 The terminations to power on the Voltage Optimiser

This is the second installment of our voltage optimiser install at the Double Tree by Hilton in Swindon.
We both thoroughly enjoyed this project and have several more coming up.
It's good to be the design team, the install team and the commissioning team on these projects. The problems are ironed out at the planning stage so the installation goes really smoothly.

Seeing that spanner across the bars gives me the willies,even though it's off,still creeps me out.⚡⚡⚡☠️☠️☠️

You can get a butane powered heat gun fairly cheaply. They are just dual function mini blowtorches that run off lighter gas. You install a catalyst block on the front to get them to produce heat without flame. I've got a little Dremel VersaFlame which currently costs about £40 on Amazon. It's small and low powered, but pretty much perfect for a quick bit of shrinking. It also has a soldering tip for use as a basic low power iron.
There are plenty of others on there, some for as little as £20. Not sure how good the others are, but there's a Draper one for £20 which would probably not melt/explode, although I don't think it has the little curved deflector to heat both sides evenly.
Not that tape is evil, or anything, just if you wanted a way to cheaply be able to shrink stuff with the power off.

Been waiting for this as an electrician from Canada I find your work fascinating

Nice. Back in 2010 when the government had many incentive schemes for renewable installs etc I was going around fitting single phase voltage optimisation units in homes all around the north and midlands. Eventually the company stopped offering them to clients as the constant switching on and off was driving the home owners mad. I get the theory if you're living close to a substation and your intake voltage is 250 plus, but they just seemed a bit gimmicky to me for a regular home.
They seem more suited to a large commercial/industrial setup.

lovely job

[@RichardArblaster]

Great job 😎

Hi Tony, another interesting video, the optimiser is only going to save money on resistive loads i.e. electric kettles & ovens etc. it will not make any difference to devices using SM PSUs these already lower the voltage/wattage to a lower level also remember this applies all the led lights which now replace the old resistive type lamps. Obviously as it's a hotel there will be a lot of resistive load devices, I look forward to the results Tony if you are able to obtain them in the future. Regards from Ray (the old sod) from North Wales.

Blooper reel coming soon 😂👌

[@tinasmith6260]

Tony you seriously need a new Milwaukee M18 Cutter, M18 Stripper and M18 Crimper

[@sergiofernandez3725]

Little thumbs up Tony

[@chrisfox8125]

Is there any reason why the ACB wasn’t racked out and locked, tagged off?!

[@DanielCraigie]

Thanks for posting the video. The camera occasionally caught the right hand side of the mains bus bar(s) and you could see single core cables tapping off (before the links) which seemed to follow the same direction of the bus bars down to the distribution panels. Does this mean that the optimiser is covering most but not all of the load in the Hotel? Could there be any issues with L1/L2/L3 phases running at different voltages inside the same building?

[@jamesmee6696]

Hi Tony I think it might be beneficial to upgrade your Crimper tool.. as it happens I have got the Klauke EK120/42 CFB for sale complete with die set if you’re interested as I don’t tend to install the big cables anymore. Interesting video but how do you achieve volt drop on long run cables (eg) sub mains when the incoming voltage is decreased.?

[@stuartolseen214]

Hi Tony
Wouldn’t it be beneficial to install a three way by-pass switch in the event of a failure to the optimiser and maintenance purposes

The principle of energy conservation states that energy cannot be created. This is the base of physics. If they need 200kWh to keep the hotel temperature at level, then it will be 200kWh (plus the loss on the "optimizer") in any shape of form. There is no free energy. If you use resistive load, like a water heater, then it will result longer heating period, but the end result (E=P*t) is the same. If you use heat pump, fridge, led lights etc, then they will not care due to the inverter. You can save with insulation, lowering comfort temperature, using more efficient or dimmable lights etc. 253V is just in the limit, but at the end of the final circuits it will be far lower. If you start at 226V, that is already below than the 230V nominal voltage. Then you can end up below the norm at the final circuits.

[@meeganian]

Do u ever use contact connection grease?

[@irechopshop]

But surely less voltage = higher current and as metering is normally in KWh how can they be saving money

[@timbo19]

P=IV but you are wrongly assuming that P stays the same. Take, for example, a simple resistive load. I=V/R so if you reduce the voltage then the current flowing through the load also reduces.

[@sdgelectronics]

Your assumption is only valid for certain loads.

[@brianoceallaigh8714]

No gloves! PPE for electric shock! would not get away with not using any here in Ireland, health and safety would have you run off site 😂

[@spewmister]

Why would he need PPE for electric shock if the systems isolated?

[@obd6HsN]

Either you have safe isolation - and you don't need gloves - or you don't, and you need full arc flash gear.
