For these boards they really need to make you like yellow plastic fuse carriers that’s fully cover everything and can be sealed in place but a very obvious that there’s no fuse in so there’s not live parts left

@residualelectrical 2 дня назад

Yeah, that’s a great shout to be fair!

@wazza33racer 2 дня назад

Was talking to an ex electrical linesman who worked in Victoria, Australia. He said that in the past, the power authority had a lot problems with electricians wiring dairy farms with ALL the load on a single phase, at a number of farms. This was pulling one of the phases down in that area, with very unequal loading. Electricians refused to believe that they were doing it wrong. To be fair, in rural Australia most properties were single phase, single line and electricity was a new thing.

@teambluelotus97 2 дня назад

Amazing comprehension on the science as well as the practical. We could all learn a thing or two from you man. Keep up the good work!

@residualelectrical День назад

Thanks man very kind!

@brianoneill350 2 дня назад

Thank you so much for explaining about the upfront fuse. Really appreciate the knowledge you have and share.

@residualelectrical День назад

No worries! Glad it’s been helpful!

@tangojango44 День назад

Logging the solar generation directly would have helped to confirm if it was generating at near perfect 1.0 PF and thus the inverter itself ok. When the load and generation are closely matched, the PF values can vary wildly as it swings in the balance between import and export. The overnight load PF looked generally ok, so it's probably not an issue with the base loads themselves.

@residualelectrical День назад

Yeah for sure, we was only asked to get KWH across a week but seeing how the PF was after a week I wish I logged the solar and the mains separately too!

I do love the CA stuff.

It’s nice kit for sure!

@camerondorrington3097 День назад

Solar will make your power factor look bad. Also not a good idea to disconnect the CT from the logger while it is connected to a live circuit.

@inothome День назад

Generally yes, never open circuit an energized CT. But I believe those were Rogowski coils and those are safe to disconnect while the primary is still connected. Plus a lot of power logging devices will ether use the Rogowski coils for ease of installation or if actual CTs they will have internal resistors or MOVs to limit open circuit voltage. But your everyday CT, correct, never open circuit the secondary when primary is still energized.

Love the videos, keep up the good work, you say “yer” so much 😂

@residualelectrical 2 дня назад

My bad, I’m terrible for filling gaps with umm’s or yea’s 🤦🏼‍♂️ thanks for tuning in!

@tullgutten День назад

The shit power factor at night is probably a lot of cheap led bulb drivers and different low power electronics that adds up

@residualelectrical День назад

Sure, but it’s a lot better than during the day time!

@ollieb7394 2 дня назад

Nice work man 👍🏼 have a look at slotted split screwdrivers, they work really well at wedging into slotted screws so you can work one handed.

@residualelectrical День назад

I think Klein do one? Always thought it looked cool!

@samd2660 День назад

I don't know whether there's anything official on it and not an electrician, but wouldn't it be better/easier/safer to install the panels from the bottom upwards instead of top down, especially when wearing PPE and balancing screws on drivers so if it falls it's more likely to end up on the floor instead of in the board.

@residualelectrical День назад

There is a little gap at the bottom of the last panel, so if that goes on first and you drop a screw it ends up under there you need to remove the panel again, that’s was my thinking anyways it doesn’t really matter 👍🏼

@inothome День назад

Data is cool!!!!! Those increases to closer to 1 power factor are probably heaters. Motors and capacitors will both lower power factor unless of course you have them balanced and cancel out. But seeing the times and increase in demand too, probably water heaters. That board with the horrendous PF, that was the board with all the LED lights correct? Cheap, no PF correcting LEDs will have the worst PF of any device. I doubt any single inverter is doing all that, but easy enough to turn off devices and watch the PF to find out. And I know some places have more lights on inside during the day, underground than at night. And kudos to wearing leathers over the rubber gloves. So many fckuers wear the rubbers without protectors and without the leathers, it just ruins and almost makes the gloves useless. Even class 3, 30kV gloves, I see so many wearing without the leather protectors not realizing one strand of wire will go right through the rubber gloves. Anyway, rant off. Happy to see the leather protectors and all those numbers from power loggers! Stay safe!

@residualelectrical День назад

Thanks man, I agree!

@jaapaap123 23 часа назад

On that second logger, even when the solar isn't producing anything, the power factor is between 0.5 and 0.8. Isn't that a bad thing?

@terencelawrence1050 День назад

magnatize your screwdrivers and did you contact bno {buisness network oporator} about missing fuse carriers

Building Network Operator - that'll be the landlord or management company who has tasked him to do this job anyway

Mike, great video.. random question not related to this vid but I keep meaning to ask where you got your hi Vis workwear from? Thanks

@residualelectrical День назад

Thanks bro, I got mine from workwear express 👍🏼

@three-phase562 2 дня назад

Nice electrical sleuthing. Unfortunately now the way to progress is to look at the total incoming supply and establish what the pf there is or you are getting into more sophisticated wave for monitoring on that board, but that still isn't going to tell you what is happening at the incoming supply.

@residualelectrical День назад

For sure! Wish I logged both the solar and whole supply in hindsight! We wasn’t there for power factor initially though, just KWH usage across a week

@Sparks0001 2 дня назад

Great videos, really interesting! How does the metering work there, I thought when there is a BNO like this appears to be with the Ryefield board, that is all pre-meter, then the individual flats and the LL supply all have their own meters, is that right? If so, I wonder if the LL is being billed for the EV use on their meter, is billing the users, but isn't taking that out of the service charge calculations so is getting double bubble on it

@residualelectrical День назад

Yeah I’m suspicious of the EV billing also, I believed there is an upfront meter and then all the flats are metered, so LL should be total - tenants if that makes sense 👍🏼

@Sparks0001 День назад

@@residualelectrical Ok, in that case could the tenants be being measured in kWh on their meters, but the primary meter is being billed in kVA, so that is then getting hit with all the power factor issues that would not be billed to the individual tenants? Or maybe a tenant has bypassed their meter somewhere if they are in their individual units!

@residualelectrical День назад

I think that’s exactly that! I’m awaiting their billing details so I can see if they are being charged for bad PF or KVAR etc 👍🏼

@Sparks0001 День назад

@@residualelectrical I manage a very small commercial building, and one of the intakes has a 100A 3-phase head, and off that, there is a three phase meter for one tenant, the two separate single phase meters for two others, one of them needs a meter swap which will take them all offline, and when speaking to UKPN they suggested I may want to re-jig it so I become a BNO so the that the intake goes into a Ryefield board I manage, and then the individual meters come off that, but with no metering between the service head and the new Ryefield board, this is only a 100A supply, so maybe when it is 400A or whatever you have there it's different (I am not an electrician!)

@brianoneill350 2 дня назад

What are the gloves you put over your gloves. Thanks

@inothome День назад

Leather protectors to protect the insulating rubber from damage. You are required to wear them over any rubber insulating gloves, although way too many people just wear the rubber insulating gloves and no protectors thinking that's ok. Until a strand of wire pokes through the rubber and lights you up.

@brianoneill350 День назад

I thought that was the reason. Many thanks. Take a look at the Shelly products. Amazing way to track usage etc for small commercial/industrial/domestic for a budget solution which is cost effective.

@inothome День назад

@@brianoneill350 I actually have a bunch of Sonoff / Wemos devices flashed with Tasmota I use to monitor building loads and tempuratures. I converted the Sonoffs to use CTs instead of passing all the current through the unit itself. Then have an AWS server running an MQTT broker, Node-Red, InfluxDB and Grafana to log and make all the screens. There are other ways too, like Home Assistant, but last I checked you had to run a local server for Home Assistant and I have devices spread out across my area, so using a remote server was better. I also set this up 5 year ago and for sure things have changed, but this still works for what I need.
