Could someone please suggest types of data loggers that can be used to log 3 Phase parameters on the Low Voltage side of a transformer.

Thanks

The basic use of the data logger will be to read real time current, voltage or/and power to reflect the effect on load change at the end of consumer line.
 
These meters:

do logging. You can also log with their app from a PC if you need more capacity then they are available with.

They are a bit pricey.

The log interval is on the order of several seconds per log from the PC. I don't know how fast it will long internally.

I like the microdaq meter @rbelli1 linked to - on the "cheap" end of pricey, yet the specs look good. Dranetz is a big name in this field, but firmly in the "ouch, my wallet hurts" side of the pricing spectrum. Fluke offers several models in the mid to high end of the price range.

I've used 3 phase power quality meters and loggers (AEMC 3945 and Dent DataPro, both models have since been discontinued and replaced with more modern gear) that will do what you want. As I recall, AEMC pricing was somewhat higher than Dent, but both were cheaper than the competition at that time.

I recommend looking over different manufacturers offerings, and making up a pricing/spec spreadsheet. It doesn't factor in as much if this is a permanent installation, but significant cost is added obtaining a range appropriately sized current probes (be they solid core, split core, current clamps or Rowgowski coils). You'll learn a lot in the course of researching power meter offerings and the current probes that will work with them.

It really depends on what you are looking for - basic power logging is easy, harmonics more difficult, and transient disturbances even more so.
