ION DC Offset

[JSmith]

I have an ION 7650 and had a request to meter DC Offset (DC Voltage and Current) on my AC lines. Does anyone know if this is possible? If so, How can it be implemented?

Regards,

Hello @JSmith,

I have noticed that your topic is still unanswered.

@sesa205386_brid do you think you can advise on this topic?

Have a nice day.

ION meters that are designed to be transformer coupled to an AC power system are designed to remove/filter DC from all measured parameters.

The one exception is voltage waveform captures. The Waveform capture module's waveform logs will register the DC voltage present between a line and neutral (software is required to retrieve and display logged waveforms).

Thanks! What software is required to see the DC Voltage?

[Charles_Murison]

The software would be either Power Monitoring expert or ION Setup to see the waveforms off the meter. There still is no real-time value of the DC voltage. The wavforms would have to be triggered from events (eg sag/swells) or from a manual trigger.
