Powerful Troubleshooting Capabilities

The Fluke 430-II products were specifically designed with the needs maintenance engineers and technicians in mind; users who need to get to the solution of the power quality problem as quickly as possible so that they can minimize expensive downtime. The measurement process and display of data is optimized to get to the most important information as quickly as possible. Multiple parameters are measured simultaneously and displayed in formats that quickly describe the state of the power quality of the system. Data can be quickly accessed as simple digital values, trend graphs, waveforms, phasor diagrams or analyzed and organized into tabular format such as the event data where the magnitude, duration and time stamping enable rapid correlation to problems experienced.

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.

The System-Monitor Overview Screen
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.

PowerWave Data Capture
For some users, load 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 model 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
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 this patented Unified Power function 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.

SystemMonitor – Check Performance Against EN50160 with Ease
The unique System-Monitor gives you an overview of power system performance (there is no button or single function) 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.
