Power Analyzers

Just got done using the Eagle 440 and what a wonderful tool for analyzing what is going on in an area of question. Just hook it up to your USB port and transfer the data that was collected to your laptop. This was the first time I ever used this and I was amazed especially with its built in CTs for its power source and the smallness of the unit. It sure doesn’t take up any room. What everyone else using?

Nice.... We usually write those complaints up for meter and test if we cant find a problem. They have a recorder that plugs into the meter channel and than the meter piggie backs onto that.

The reason this is being used is to record a 3 phase bank of 50s, just making sure there are no elevators that are being used on this bank. Getting ready to run the customers off of a 400kw Cat generator and do not want any surprises, since this is a three day Clearance that they will be powered from the generator.

I can't think of the brand, but we have two; one for single phase like what Dave was describing and another big ol honker that we'll use on 3 phase.

Really we won't set a recorder unless the customer pays for it or it's a high profile customer. With all the other tools available it really isn't that necessary. I can pull up feeder trips, outage run backs, current and past substation data, etc, etc.

Now with the "smart meters" being able to identify power quality issues in the beta stage the recorders will soon be a thing of the past.

I have a voltage recorder recording on another computer...if I remember I'll post up an image of what one looks like.

Here's a few graphs from one earlier this year for those who don't know what they look like...
