Fluke 1744 Three Phase Power Quality Logger
Assess power quality and conduct long-term studies with ease
Compact and rugged, the Fluke 1740 Series three-phase power quality loggers are everyday instruments for technicians who troubleshoot and analyze power distribution systems. Capable of simultaneously logging up to 500 parameters for up to 85 days and capturing events, the Fluke 1740 Series helps uncover intermittent and hard-to-find power quality issues. The PQ Log software quickly assesses the quality of power at the service entrance, substation, or at the load, according to the latest EN50160 standard.
Plug and play
All three 1740 Series loggers feature easy plug and play setup, for immediate use. The current probes are connected to the logger with a single plug. The instrument automatically detects, scales, and powers the probes using line power from the measured voltages. All accessories are individually calibrated and can be shared with multiple Fluke 1740 series loggers. Once it is connected, logging begins with the touch of a single button!
Electrical shock protection
The Fluke 1740 loggers feature double insulated enclosures and accessories to help prevent electrical shock when coming into contact with blanket bus bars, terminals, or cables. They are also designed to meet the stringent safety standards for use in 600 V CAT III and 300 V CAT IV environments.
Loggers for every application
The portable Fluke 1740 Series power quality loggers are designed for easy installation and use, anywhere in low- and medium-voltage applications. There are three models to choose from to meet your basic or advanced power logging needs:
Fluke 1744:
Includes the same features as the Fluke 1743. In addition to common power parameters, the Fluke 1744 also measures voltage and current harmonics, interharmonics, mains signaling, unbalance, and frequency.
Measure all power quality and power parameters
The Fluke 1745 and Fluke 1744 log over 500 different parameters for each averaging period. This allows you to analyze power quality in detail and to correlate intermittent events, helping to identify the root cause of disturbances. For basic power logging, the Fluke 1743 captures all relevant power parameters.
Calculates current harmonics
Fluke 1745 and Fluke 1744 loggers can calculate the limits of current harmonics to predict overload of the grid according to the standards VSE, VEOE, VDN, among others. This powerful predictive maintenance feature enables current harmonics to be observed before a distortion appears in the voltage.
