运行算法就弹窗报错“System throttled due to Over-current”。用 Power GUI 抓了 10 分钟的电源 log 数据，如下所示：
0721log.csv.zip (30.9 KB)
图像化显示后，并未发现有超过报警阈值的数据，接下来如何排查具体的过流报警的原因，请帮忙指导，多谢。

电源模式选择 MAXN 时，不光会产生过流报警，且会出现重启。
电源模式选择 120W 时，仍会产生过流报警，但不会出现重启。

please check below node first. If it is OC3 event, then power GUI tool won’t capture it.

cat /sys/class/hwmon/hwmon*/oc3_event_cnt

确实是 oc3_event_cnt 在增加，这三个 oc_event_cnt 分别代表什么意思？有对应的文档介绍吗？多谢
