Monitoring Home Electrical Usage
 
There was a thread a while back about different ways of monitoring power consumption. It got me interested and I bought the hardware/software and got it installed yesterday.

The unit I bought is called the TED 5000 and can upload the data to Google to provide unlimited historical data if you want to compare month-to-month or year-to-year.

It also has a small, portable digital display (size of an ipod touch) so data can be monitored without being at the computer. All system communication is done via powerline carrier technology.

It allows you to enter all of the billing info from the utility - rate, tiers, taxes, etc. so you can monitor current & projected costs. This will allow a user to verify correct billing from the utility

I have 3 Circuit Breaker Panels - 2 main panels and 1 generator panel that are denoted as MTU 1, MTU 2, and MTU 3 on the following screenshots. Data from the gen panel is only available when the gen is running.

It also allows you to monitor key loads so you can modify usage and decrease consumption. I am monitoring my 2 HVAC systems.

If you are a gadget freak, this is pretty neat. Here are some (crude) screenshots

Looks impressive; even to a low-brow like myself. How will you use this information?

Elusive 05-25-2010 03:07 PM

More a toy than anything, but it does allow you to see the effects of certain loads (HVAC, etc) in real $

The Google inspired concept is that once you are aware of the cost, you will want to modify your consumption

If you go to my album and click on the screenshot, it is alot easier to see

Sounds like you have a larger service....I'd guess at least 400 amps?
I am familiar with systems similar to this, but on services greater than 2000 amps at 480V. The software is great...you can monitor any aspect of the load characteristics and power usage. With the focus on going green, you will see more and more of this on smaller applications.

How are you getting load characteristics with out current transformers on the seperate pnls and equipment.I guess you installed those..?

400A Service

CT's on all 3 panels

I was very interested to hear about real experience with this product... I just placed my order...
question how do you monitor individual appliances like AC units????

I also have 2 panels 200Amp each...

Thats pretty cool, Gary. How long have you had it?

Elusive 05-26-2010 05:35 PM

emudryj - In the setup (which is very easy) there is a "Load Profile" tab which allows you to monitor 5 loads. Once you have the MTU (CT's & voltage sensor) working on a panel and establish a baseline, you setup a load profile by pressing the "Learn" button and turning that load on. The system then recognizes and monitors that load when it is on.

Rob - Just started this week. We have a had a lot of clients (dozens which seems like more than a coincidence) over the last year complain that PEPCO is intermittently charging them way more than normal (i.e. interior townhouse getting billed $1900). I thought I would check out the technology as a possible tool to identify inaccurate billing.

Note to those with Home Automation systems. The system uses powerline technology transmitted at 130Hz. It interferes with X10 and Insteon systems which transmit at 120Hz. I have ordered filters to hopefully eliminate the interference to my HA system

Don't you have meters on the house that you can read? Where we are at, we actually have to read them ourselves, calculate the bill, and go into the co-op and pay it.

How can they screw you, if you have a meter? Meter inaccuracy?

Pretty cool stuff there.......:thumbsup:

Elusive 05-26-2010 05:55 PM

Andy - here below the Arctic Circle they send a meter reader out every month to read the meter. :grin:

The customer has no idea how much power they are using until they receive their bill the following month

We have had dozens of reports of monthly bills going from say $300 to over $1000 and then back to $300. The local utility sends an employee out to verify the correct operation of their meter and the customer is screwed. It happened to me last year where my bill jumped 150% of the highest it has ever been in 12 years and then returned to normal. As I said, it seems more than a coincidence.

PS - Thanks for getting the trim unit out so fast :thumbsup:

Great!!! it seems to be fairly easy... I have a good working relation with most new technologies so I do not expect to have big issue... now let me ask you someting...
I have 2 panels, 200 amps each.
I ordered the TED 5002C that comes with the handheld, the gateway and 2 mtu/ct.

the MTU/cts goes one on each panel and the gateway plugged in to an electrical outlet probably close to my computer.

Am I missing any extra piece of hardware if I want to monitor specific loads like the A/C, heater, etc???
will I be fine with the 2 MTUs/CT???

If I do I would like to know to order right away and get it all togheter...

I would appreciate your comment on this

forget it.....I re-read your post and now I understand better....

you set a baseline with whatever equipment you want to monitor being off.
then you hit learn and turn that equipment on... the difference in consumption is what the equipment is consuming....

got cha

Connect the gateway to your network switch and you're in business

You can more closely monitor specific loads if necessary with additional MTU's.
