3 phase metering

[Sparky 63]

Evening Gents,
I have been tasked at work to install a 3 phase meter measuring power usage in a commercial kitchen area.My question is - Is there are a product out there which can be permanently clamped around a three phase cable which provides a digital display and will provide, a record of kw usage and will record , daily/weekly monthly usage . I doubt if there is a item of this equipment available but hey ho you never know.

Cheers

why not chop into board supply and put a 3ph meter in.

smart meters have the features you seek so your friendly local wholesaler should be able to get one

Don't think so other than an sub meter.

Useful link, you can look for the rest lol

Yes and they are very common, try google, a wonderful tool, I bet it will take seconds to see what you are looking for.

He was only asking Mike:sifone:

Hi there, I was trying not to chop into the board and rather try to adopt a system that works on toroidal transformer being wrapped around the cable, and the currents being induced into the metering

 

[Plonker 3]

See post #4 there a big clue in that one.

cheers mate

OWL do a three phase version of their home energy monitoring system, it goes up to 200A/phase with the larger CTs.

Hi Dave does this equipment require a direct electrical connection to phases ?

:frown2: You still haven't googled it yet then? I have and it is very clear with lots of instructions, go on, give it a try

did is you not see the word CTs in his post?

This looks like the solution called for in this case. Far cheaper than any of the CT metering setups I have ever come across... by a long shot !

Hi Dave does this equipment require a direct electrical connection to phases ?

It requires batteries and the rest is done with CTs, you just have to program the supply voltage and any other parameters you need.

I used this as a rudimentary way of monitoring a generator at a festival a couple of years ago.

 

[Sparky 63]

Hi Andy , how does this equipment work , a toroidal tx around each phase i suspect and then current rating transmitted to metering unit then ?

 

[davesparks]

Have you looked at the system yet?
It uses CTs to measure the current, does a bit of clever maths and displays whatever you want it to.

hello Dave any ideas on make and model number

 

[Sparky 63]

nope cant find it -have you a make and model no i could google

 

[davesparks]

OWL is one make of such things, you'll have to choose which model suits your needs from their website.

Should do the job, there are clamps which go around the cable without actually having to disconnect any wires, the instruction download should tell you more.

 

[davesparks]

Come on man, there's a link in post 22 FFS!

 

[Plonker 3]

Anyone waiting for the OP to ask for someone to go fit it for them too?

Nah, we'll have order it for him first, and sign for the parcel.

 

[Guest77]

I assume you got a thanks for your help Dave? lol

 

[Plonker 3]

What help the OP can't find what he wants lol

 

[7029 dave]

These type of gadgets are okay, but for true accuracy he will have to fit an meter to the wall, only MO.

Why can’t Electrical Trainee’s stick to setting fire to domestic installations?

 

[shanky887614]

clamp meters are all well and good but they will never be as accurate as an ammeter

 

[Sparky 63]

Thanks mate it much appreciated
