3-phase power analysers pinpoint problems faster

Fluke has launched a new series of three-phase, handheld power quality analysers with innovative features that enable power quality problems to be accessed faster and in greater detail.

Fluke has launched a new series of three-phase, handheld power quality analysers with innovative features that enable power quality problems to be accessed faster and in greater detail.

The first instruments of their type to meet the CAT IV 600V safety standard, they can measure all phases and neutral on virtually every connection in a low voltage application.

The new Fluke 433 and 434 Three-Phase Power Quality Analysers are troubleshooting tools designed for applications in industry, healthcare, business, public services and all areas where power quality is critical.

They measure all power system parameters in accordance with the latest IEC61000-4-30 standard, like true-rms voltage and current, frequency, power, power consumption (energy), unbalance and flicker, and can track (inter-) harmonics.

They also automatically capture events like transients (as fast as 5 microseconds and as high as 6kV), interruptions, rapid voltage changes and dips and swells.

The Fluke 430 Series feature a unique AutoTrend function.

This provides fast insight into changes over time without the need to set up specific threshold levels or interval times, or to manually start the process.

Every reading is always recorded, and it is possible to switch between data and trend plots, and even to zoom in and use cursors for detailed analysis, while background recording continues.

With AutoTrend, no valuable data or time is wasted setting up the instrument and starting separate measurements.

The 430 Series also offers a System-Monitor feature.

With a single push of a button, System-Monitor provides a comprehensive overview of the power systems quality by checking the conformity to limits specified in EN50160 or to a users own specified limits.

The overview is displayed on a single screen, with colour-coded bars clearly indicating which parameters fall within the limits.

A list with all events falling outside the limits is available.

Drilling down into these events is easy, while the underlying trend data of all measured parameters for the three phases and neutral are stored and can be viewed and analysed in detail using cursors and the zoom function.

As four-channel instruments, the Fluke 433 and 434 can simultaneously measure voltage and current on all three phases and neutral.

The series supports all commonly used wiring schemes.

They are also the first instruments of this type to meet the stringent 600 V CAT IV safety standard required for measurements at the service entrance, and can be used on virtually all power connections and outlets in low-voltage power-distribution systems.

Optimised for mobile applications, the rugged Fluke 433 and 434 run over 7 hours on a single battery load.

The large data memory stores up to 50 screens and up to 10 measurements each comprising 32 parameters ? including set-ups and trend data ? all of which can be transferred to a PC via FlukeView software for analysis or use in reports.

Both models also feature versatile scope functionality.

The 430 Series three-phase power quality analysers are supplied in a hard case as a complete package with four clamps and five test leads.

A kit to upgrade the 433 to the 434 specification (extra functionality plus FlukeView and optical connection cable) is also available.
