What can I use

[secureiam]

I am not a sparky.

However I suspect an electrical issue maybe occurring in a supply to an out building where part of an alarm system is housed.

It’s only the part in this out building that’s affected.

It could be the switch mode power supply doesn’t like the feed comming in and it’s being upset for around 40 seconds in the early hours of the morning.

So far one event 1:45 am a few days later 3:35 am both lasting around 40 seconds.

Anything I can use to monitor Viktsge current and frequency using clamps that can record the data for a week or so that is under £100?

No. Even to hire such a thing for a week would be far more than £100.

Yes, assuming you have a laptop. Buy a cheap USB analogue to digital converter. (AKA “USB Oscilloscope”.) Less than £50 on eBay and probably even less on AliExpress. Connect one channel to a current transformer (with a shunt resistor I guess??), and the other to measure the voltage a suitable normal (voltage) transformer.

Then I guess the challenge is whether the supplied software will record for very long periods.

hmm thanks.
