Pinpoint power quality problems faster, safer and in greater detail
These three-phase power quality meters help you locate, predict, prevent and troubleshoot problems in power distribution systems. These easy-to-use power quality tools are a “must have for any person who maintains or troubleshoots three phase power. The new IEC Class A standards for flicker and power quality are built right in to take the guess work out of power monitoring.
Applications
- Frontline troubleshooting – quickly diagnose problems on-screen to get your operation back online
- Predictive maintenance – detect and prevent power quality issues before they cause downtime
- Quality of service compliance – validate incoming power quality at the service entrance
- Long-term analysis – uncover hard-to-find or intermittent issues
- Load studies – verify electrical system capacity before adding loads
- Energy assessments – quantify energy consumption before and after improvements to justify energy saving devices

|
- Complete three-phase troubleshooting tool: measures virtually every power system parameter: voltage, current, frequency, power, power consumption (energy), unbalance and flicker, harmonics and inter-harmonics. Captures events like dips and swells, transients, interruptions and rapid voltage changes.
- The Fluke 435 features 0.1 percent voltage accuracy making it fully compliant with the IEC 61000-4-30 Class A standard
- Logger function: record the detail you need. Detailed, user-configurable long-time recording gives you the MIN, MAX and AVG readings of up to 100 parameters on all 4 phases with selectable averaging time down to 0.5 seconds. Enough memory is available to record 400 parameters with 1 minute resolution for up to a month.
- Four channels: simultaneously measures voltage and current on all three phases and neutral.
- AutoScaling: easier trend analysis with automatic scaling of the vertical axis you
will always use the full display to view the waveforms.
- Automatic transient display: captures up to 40 dips, swells, interruptions or
transients automatically.
- Meets the stringent 600 V CAT IV, 1000 V CAT III safety standard required for
measurements at the service entrance.
- Rugged, handheld instrument operates for more than 7 hours on included
rechargeable NiMH battery pack. Menu-driven interface simplifies operation.
- Extensive data analysis possibilities. Cursors and zoom can be used ‘live’ while
taking the measurements, or ‘offline’ on stored measurement data. The stored
measurements can also be transferred to a PC with FlukeView software (included with Fluke 435 and 434).
- The Fluke 435 comes with Power log software to analyse recorded data and to
create reports.
- Complete package includes everything to get started: 4 current clamps, 4 flex
clamps with Fluke 435, 5 voltage test leads and clips, line adapter/battery
charger and hard case.
- Complies with IEC 61000-4-30 measurement standards

AutoTrend - Quickly see the trend
Unique AutoTrend gives you fast insight into changes over time. Every displayed reading is automatically and continuously recorded without having to set up threshold levels or interval times, or having to manually start the process. You can quickly view trends in voltage, current, frequency, power, harmonics or flicker on all three phases plus neutral. And you can analyze the trends using the cursors and zoom function – even while background recording continues.
AutoTrend automatically records all displayed parameters in the background.
SystemMonitor - Check performance against EN50160 with ease
With a single push of a button, the unique System-Monitor gives you an overview of power system performance, and checks the compliance of incoming power to EN50160 limits or to your own custom specifications. The overview is shown on a single screen, with color-coded bars clearly indicating
which parameters fall outside the limits.
The System-Monitor overview screen gives instant insight into whether the voltage, harmonics, flicker, frequency and the number of dips and swells fall outside the set limits. A detailed list is given of all events falling outside the set limits.
