PicoLog 1012

Post by 1939bruce » Thu Sep 22, 2016 3:03 pm

We need to do something very simple and that is log three phase electric service.

We need to attach current clamps (CT’s) to the power for all 3 phases. We have a great number of CT’s in stock that have the standard 0.333 vac output, we would like to use these, in fact this is the reason we bought Pico we thought his would be easy!

We also need to connect the voltage to the Pico, with ranges up to and including 600 vac.

Need help in determining how to do this, we understand we need to convert to vdc (our we think we do!) and that we need to transduce the 600 vac to something much smaller and it needs to be vdc!

We are hoping you can lead us to the proper places to do this, without tripling the cost of the logger!

Please contact support@picotech.com explaining in detail what/why/how you are wanting to measure the power, and what results you are looking for. We will then be able to point you in the right direction.

Be aware that when connecting to mains there are safety considerations that ALWAYS need to take precedence over cost.

Hi there,
I'm looking to do something similar. Measure voltage from 3 phases @ 230V each. Did you manage to do what you were trying to do? If so how ?

Hi,

Unfortunately there are no short cuts to safety.

What you need to do may be fairly simple, but you will be dealing with potentially hazardous voltages, which means that you should be considering equipment, and procedures that provide adequate protection. The PicoLog 1012 is a data logger for use with safe voltages only, because to connect to it you need to use a terminal board that has exposed connections. Included in the procedures that you should consider is protection from the return to ground path for any hazardous voltages that might appear at the data logger (including any failure mechanism). If you were to accidentally touch an exposed connector, that return path could be you!

So I would suggest that you look at the answer that I provided at the following location: post105461.html#p105461
