Fluke 1746/30/EUS three-phase power quality logger
The Fluke 1746/30/EUS is a logger for measuring power quality in three-phase systems. It is used to determine how voltage, current, and load behave over time - not just at the moment of measurement. This makes it suitable for troubleshooting, energy monitoring, and documenting whether an installation performs as expected.
The instrument measures, among other things, voltage, current, power, power factor, frequency, harmonics up to the 50th order, interharmonics, flicker, and unbalance. At the same time, it can log up to 500 parameters, providing a very detailed picture of operation. This is especially relevant when faults or disturbances are intermittent, and data needs to be collected over time.
An important part of this model is the included flexible current probes measuring 24 in / 60 cm for up to 3,000 A. They make it easier to wrap around conductors in panels and installations where space is limited. It is also worth noting that the instrument can be powered from the circuit being measured, which simplifies setup in the field.
Practical everyday use has been considered. Connection and download can be handled via Ethernet, USB, Wi-Fi, or Bluetooth, and it supports reporting according to standards such as EN 50160 and IEEE 519. This means that you not only get raw measurement data but also a basis for documenting power quality in a way that is easy to work with.
For tasks in electrical panels, at service entrances, in sub-distributions, or with larger systems, this is a relevant logger when you need to see both slow trends and events that can explain operational problems. It is therefore most interesting for technicians and engineers who work with troubleshooting, energy analysis, and power quality in three-phase installations.
