Electrical power energy auditing

[sharavanen]

     I am  doing a project on power supply monitoring system with labview. The main aim of the project is monitoring and data logging the signals from non contact type hall effect current sensors. Voltage and current are the two main parameters which is to be measured. Electrical power is the another parameter need to measure. I don't know how to start the task.

Help me......

     Just give me a basic idea of how to start and provide me a basic vi for the task.

Hi sharavanen,

Sorry for replying late.

I suggest you refer to COMTRADE Logging examples from EPS toolkit. This example provides a solution to log voltage and current parameters (and other "electrical power" parameters if you add such VI's mainly from PQ category in the palette). 

There are things that you should notice:

1. Choose your wiring method on the block diagram. 

2. If you need to log more paramters, you have to add such VIs yourself. You can refer to Power Quality examples in this regard. 

3. If you choose to use other target and/or modules than what's in the example, you have to modify the target in the project and/or FPGA VI to convert the fixed point data precision (details in the example's builtin help and description).
