Voltage monitor ac 230/400v

[bigspark17]

Hi where could i get hold of a voltage monitor or similar that is designed to keep track of supply voltage.?
I have a commercial site 3 phase that i suspect is loosing voltage on one phase causing some issues around site.
Any help or past experiences appreciated.

You could hire a 3 phase data logger and set it to log at desired intervals, alternatively the DNO will often do this for you for free, if you give them reasonable cause to investigate a supply fault. I assume you know which phase you think you’re losing, in which case you could take some basic min/max readings with a suitable multimeter.

If they have a ups for IT equipment, it often has logging built in.
If you are lucky, it is on the phase you are concerned about.
