I just posted a question that you may have an answer to. My customer wants to be alerted when grid voltage and frequency deviate more than +/-5% of 480V or +/-2% of 60Hz. On VRM via the alarm notification options. Possible? Probably, and ChatGPT thinks it is. But would love to hear from experience that it works before I spend $500 or so (meter is about $350 and one of the 3 CT’s I need is about $150). Thanks!
