three phase metering code (AN13338) scaling down to single phase metering

Mr7 — Mon, 10 Feb 2025 13:52:58 GMT

Hello NXP team,

I am currently working with a single-phase metering code (AN12837 )and would like to know that can i use Three phase metering code(AN13338) for a single-phase metering application also with only minor modifications. Any guidance or recommendations would be greatly appreciated.

Thank you in advance for your support.

Hello @Mr7 ,

Thanks for your post. Before answering your question, I'd like to gain some background information. Given that we already have the single-phase metering application (AN12837), could you please explain why you are considering modifying the three-phase metering code (AN13338) instead?

BRs,

Celeste

Thank you for your prompt response,

Actually, my goal is to develop a common base code that can be used across multiple applications. Some of these applications involve single-phase AC, while others require three-phase AC metering. To achieve this, I am considering using the three-phase metering code as a foundation, making the necessary modifications to support single-phase applications as well.

If feasible, I would appreciate your guidance on how to adapt the three-phase metering code for single-phase use while maintaining flexibility for future three-phase implementations.

Thank you for your support!

Hello @Mr7 ,

I'm not very experienced in this matter. However, I've already asked others for assistance, and they will get back to you when they have time. Thank you for your understanding.

Hi @Mr7,

The metrology library in both single phase (an12837) and three phase (an13338) is same. The only difference is application side. The metrology library has structure-based support for single phase (tMETERLIBLPRT1PH_DATA) and three phase (tMETERLIBLPRT3PH_DATA). All the single-phase related parameters are defined in tMETERLIBLPRT1PH_DATA and three-phase related parameters are defined intMETERLIBLPRT3PH_DATA. If you need more information, please reach out to us.

Br,
