The Fluke 437 Series II Power Quality and Energy Analyzer is the world's only Power Quality analyzer that can monetize the cost of energy waste due to poor power quality and is ideal for characterizing power quality, conducting load studies and capturing hard-to-find voltage events over a user-defined period of time. Designed for capturing power quality measurements in avionic and military systems, Fluke 437 Series II is the must-have 400 Hz quality analyzer. This version is just the mainframe so you can select the ideal current probes for you applications.
Higher power frequencies mean smaller and lighter transformers and motors – a critical concern in avionic and military transport applications where weight is a primary concern. Designed specifically for these environments, the Fluke 437 Series II Power Quality and Energy Analyzer is a must-have for those working in ships, submarines, aircraft, spacecraft and other military vehicles.
Equipped with all the functionalities of the Fluke 435 Series II, the 437 Series II offers the best in power quality and energy analysis all the way to 400 Hz.
Features
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 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.
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 430 series II 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
Fluke's patented Unified Power Measurement system (UPM) provides the most comprehensive view of power available, measure:
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 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.
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.
