Overview

Do you know what makes Fluke 437 Power Quality & Energy Analyzer different from the other products in the Fourth area series?

Fluke 437can lend report and repairs as well as 50 and 60 Hertz with great value. This is really important for Lords Places like airplanes and also on ships. So it measures all the usual powerful experiences but it got the extended frequency.

People need that well those 400 Hertz Lords they’re different from the typical 50 16x modes. So these are four pieces of equipment which are very specialized.

Fluke 437 it allows the equipment to be lighter and smaller and obviously in that location it’s quite tight for space and what is important for those kinds of loads on board a ship. It defines exactly what it is Allowable. When you have onboard power on the ship because you don’t have a fixed network it’s possible that the voltage and current will modulate and go too high for the equipment.

Which is inside the ship and possibly damage it so one international it’s very important for ships well the voltage tolerance is different from what trying on a grand.

The power system also the current imbalance and voltage imbalance is a different metal as well so we can’t just use the standard test plus minus 10% that we might have on a ground basis that’s all built into.

This meter provides the result exactly according to the standard, so you don’t have to do any extra work. The way it measures is all built into the instrument so the user just has to connect up and you get results exactly as you want to see them.

What kind of measurements do those people make maybe the same kind of measurements as you would do in any electrical system but the important thing is that they have these high-frequency pieces putting?

The 42 thirds the key part when the could be damaged so we find it useful to be able to measure on aircraft systems obviously the aircraft manufacturers but also the people who supply the ground power system and also
reports you have the responsibility of connecting those ground power systems to the aircraft.

Features

  • 400 Hz measurement: By increasing the power frequency to 400 Hz, transformers and motors can be much smaller and lighter than at 50 or 60 Hz, which is an advantage in aircraft, submarines, space crafts, and other military equipment and hand-held tools. The 437 II model captures power quality measurements for these types of avionic and military systems.
  • Power inverter efficiency: Simultaneously measure AC output power and DC input power for power electronics systems using optional DC clamp.
  • PowerWave data capture: Capture fast RMS data, show half-cycle and waveforms to characterize electrical system dynamics (generator start-ups, UPS switching etc.).
  • Energy loss calculator: Classic active and reactive power measurements, unbalance and harmonic power, are quantified to pinpoint the fiscal costs of energy losses.
  • Troubleshoot real-time: Analyze the trends using the cursors and zoom tools.
  • Highest safety rating in the industry: 600 V CAT IV/1000 V CAT III rated for use at the service entrance.
  • Measure all three phases and neutral: With included four flexible current probes with enhanced thin flex design to fit into the tightest places.
  • Automatic Trending: Every measurement is always automatically recorded, without any set-up.
  • System-Monitor: Ten power quality parameters on one screen according to EN50160 power quality standard.
  • Logger function: Configure for any test condition with memory for up to 600 parameters at user-defined intervals.
  • View graphs and generate reports: With included analysis software.
  • Battery life: Seven hours operating time per charge on Li-ion battery pack.

PowerWave data capture

For some users, loads switching is a cause of power quality problems. When loads switch on, the current draw sometimes causes the voltage to drop to a level that causes other equipment to malfunction. The PowerWave function available in the 435 and 437 Series II models enables users to capture voltage, current and frequency signals simultaneously at a high speed to see which interaction is potentially causing problems. PowerWave goes beyond standard power quality measurements; PowerWave’s fast data capture mode enables system dynamics to be characterized.

Waveforms for voltage and current are continuously captured for the specified time, and are displayed on the screen in high detail; the power waveform is derived from the data. In addition, half-cycle RMS values for voltage, current, power and frequency can be stored and retrieved for analysis. This feature is particularly useful for testing of standby generation systems and UPS systems where reliable switch-on can be vital.
These UPM calculations are used to quantify the fiscal cost of energy loss caused by power quality issues. The calculations are computed, along with other facility-specific information, by an Energy Loss Calculator that ultimately determines how much money a facility loses due to wasted energy.

Power inverter efficiency

Power inverters take DC current and transform it into AC current, or vice versa. Solar generation systems usually include an inverter that takes the DC energy from the solar cells and converts it to useful AC power. Inverters can lose performance over time and need to be checked. By comparing the input power with the output power you can determine the system efficiency. The 435 and 437 II models can measure the efficiency of such inverters by simultaneously measuring the DC and AC power of a system to determine how much power is lost in the conversion process.

Unified power measurement

Previously, only experts could calculate how much energy was wasted due to power quality issues; utilities could calculate the cost, but the required measurement process was beyond the reach of average electricians. With the new, patented Unified Power function of the 430 Series II, you can use one handheld tool to determine how much power is being wasted, and calculate exactly what the extra consumption costs. Fluke’s patented Unified Power Measurement System provides the most comprehensive view of power available, measuring:

  • Parameters of Classical Power (Steinmetz 1897) and IEEE 1459-2000
  • Detailed Loss Analysis
  • Unbalance Analysis

These UPM calculations are used to quantify the fiscal cost of energy loss caused by power quality issues. The calculations are computed, along with other facility-specific information by an Energy Loss Calculator that ultimately determines how much money a facility loses due to wasted energy.

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

 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.

Logging function allows you to customize measurement selections and provides instantaneous analysis of user-selectable parameters. Measure and record power (W), VA and VARs. The 434 adds the ability to record energy consumption. Track harmonics up to the 50th, and measure and record THD in accordance with IEC61000-4-7 requirements
