TED Pro Support / MTU and Spyder on same circuit give very different readings

« Last post by GH on March 26, 2018, 10:44:29 AM »

To troubleshoot a new TED installation I have two pairs of CTs on one pair of wires coming out of a double breaker.  One CT pair is 400A split collar routed to the MTU and the other CT pair is 200A split collar routed to a spyder that is attached to that MTU.  Spyder settings combine those two CTs (ports 1 and 2).

The MTU pair and the Spyder pair give very different energy readings, Spyder is circa 5x larger and they move roughly in parallel but it varies a bit.  MTU Skp is less than 5%.

Any known issues that come to mind?  Is there a calibration setting required for the 400A CTs?

Net, Gen (where relevant), Load, and MTU History values are taken or derived from MTU data. Spyder data is only involved if you are displaying history results for a specific Spyder.

When looking at the History Tab I am assuming when your viewing the Net information the totals are coming from the MTU as opposed to spyders when your looking at spyders led  Is the correct?

Thanks for the responses.   I replaced some 60A CT with 10A since the high load on the breakers were about 6A and forgot to check the block in the spyder settings.   Realize this at the end of the billing cycle when comparing to power company bill.   I started to monitor the breakers for several days after making the changes and yeah it looks like it was at least 2.5x greater without the block checked.

TED Pro Support / Re: Limit on Number of Spyders?

The system is limited to 4 Spyders due to limited hardware resources so it would have to be done in a new model system but currently there are no plans to address it because we do have an option available that can give you the possibility of an unlimited number of Spyders if you go for the MTU Pro and Commander where you can link 2 Spyders to each MTU Pro and link it to Commander with no limits on how many MTU's you can add.

Yeah, nothing serious will happen but your readings will be about 3x's what they should be and you won't get any resolution on low current draw so you won't pick up small loads when they are the only thing on.

Developer Support / Re: Posting to a 3rd party server

« Last post by Kevin on March 11, 2018, 06:20:03 PM »

"The TED5000 has a XML based service that applications can use to poll the device directly."

żDoes TED PRO has a similar service? (besides the 3rd party posting which is very limited for remote monitoring)

For real time monitoring, we have found more powerful polling in TED5000 than posting to 3rd party. We hope to do something similar with TED PRO. żIs there a manual showing the programmable commands for polling directly the TED PRO?

I'm using the public API (see this thread) to grab the latest instantaneous watts from the MTU and Spyders, as XML.

Works well, but in the long run I plan to write my own listener to receive data via the "3rd party posting" mechanism instead.

Any chance of increasing the total number of Sypders allowed at some point in the future?  Why are only 4 supported?

Thanks,
Brock

According to the instructions you are suppose to check the 20A box if you are using a 20A CT.   What happens if forget to check the box when you are setting up the spyder settings?

Nothing fatal, I am sure!  The setting affects the gain on the channel (and possibly tweaks the response in other ways). I imagine that the incorrectly set channel  will read higher than it should, but I don't know by what factor.
