Power analysers troubleshoot three-phase systems

The new Fluke 434 and 433 three-phase power-quality analysers are designed to locate, predict, prevent and troubleshoot problems in three-phase power distribution systems.

The new Fluke 434 and 433 three-phase power-quality analysers, designed to locate, predict, prevent and troubleshoot problems in three-phase power distribution systems, are now available from TTi (Thurlby Thandar Instruments).

These easy-to-use handheld tools have many innovative features that give users all the details that will enable them to pinpoint problems faster and safer.

The Fluke 430 Series instruments can measure true RMS voltage and current, frequency, dips and swells, transients, interruptions, power and power consumption, peak demand interval, (inter-) harmonics, flicker and unbalance according to the latest IEC61000-4-30 standard.

It is also possible to verify KYZ pulse output revenue meters using an optional pulse input accessory.

Every time an event or distortion on the voltage waveform is detected, the instrument triggers and automatically stores voltage and current waveforms on all three phases and neutral.

The instrument can also trigger when a certain current value level is exceeded.

Up to 40 dips, swells, interruptions and transients can be captured in this way.

Voltage transients as high as 6kV and as fast as 5us can be observed.

Thanks to features like a user-friendly menu and handy on-screen wiring diagrams for all commonly used three-phase and single-phase configurations, the 430 Series power-quality analysers are very easy to use.

Each instrument is supplied with four 400A clamps, and five voltage test leads and clips, and a line adapter/battery charger - all packaged in a hard case.

The rugged construction and battery operation make these products ideal for demanding field work.
