What Are the Best Data Loggers for Monitoring 3-Phase Low Voltage Parameters?

Click For Summary

Discussion Overview

The discussion revolves around identifying suitable data loggers for monitoring 3-phase low voltage parameters, particularly in the context of transformer applications. Participants explore various options, specifications, and use cases for these devices.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Exploratory

Main Points Raised

  • One participant requests suggestions for data loggers that can log 3-phase parameters on the low voltage side of a transformer.
  • Another participant inquires about the specific voltage range required for the data loggers.
  • A participant shares a link to a data logger product page, indicating a potential resource for options.
  • It is noted that the voltage range for the application is 0-600V.
  • One participant describes the intended use of the data logger to read real-time current, voltage, or power to assess the impact of load changes at the consumer line's end.
  • A suggestion is made to consider specific meters that offer logging capabilities, with a mention of their pricing and logging intervals.
  • Another participant expresses a preference for a specific meter while comparing it to other brands like Dranetz and Fluke, discussing their pricing and features.
  • There is a mention of the complexity of power logging, indicating that basic logging is straightforward, while capturing harmonics and transient disturbances is more challenging.
  • A participant expresses a preference for Hobos as data loggers but is uncertain about their capability to log 3-phase data.

Areas of Agreement / Disagreement

Participants present various viewpoints on the types of data loggers available and their specifications, but there is no consensus on a single best option. Multiple competing views and suggestions remain throughout the discussion.

Contextual Notes

Participants discuss the importance of current probes and their compatibility with data loggers, which may influence the overall cost and effectiveness of the monitoring setup.

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

What voltage range?

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.
