Providing the ultimate power analyzer for use by all engineers pursuing power conversion efficiency

• World-class measurement accuracy
• Basic accuracy ±0.03%, DC accuracy ±0.05%, 50 kHz accuracy 0.2% (When using the 15MS/S Input Unit U7005)

Evaluating power conversion efficiency requires the ability to accurately measure power in every band, from DC to high frequencies. The PW8001 delivers exceptional measurement accuracy not only for 50/60 Hz, but also across a broad frequency band, including for DC and at 50 kHz. This allows it to accurately evaluate power conversion efficiency which often involves measuring multiple frequencies.

Unlocking efficiency in inverter systems: Introducing Power Spectrum Analysis (PSA)

The Power Spectrum Analysis (PSA) function, enhanced by a powerful FFT (Fast Fourier Transform) feature, revolutionizes our approach to analyzing high-frequency power loss. This advanced FFT capability allows for in-depth analysis of voltage, current, and active power, providing detailed insights into power conversion dynamics. This is crucial for enhancing inverter efficiency and minimizing waste in power systems through targeted frequency analysis. The PSA function can provide a clearer picture of electrical issues and helping to pinpoint and reduce power losses more effectively.

Up to 8 power channels optimizing your measurement

• 8-channel power measurement

Increasingly, hardware like electric vehicle (EV) drive systems that use dual inverters and electric power interchange systems in smart homes are adopting multi-circuit designs in order to utilize energy effectively. A single PW8001 can measure 8 channels of power data, allowing equipment with 8 measurement points for power such as dual motors as well as other equipment with multiple circuits to be evaluated in one stroke.

Seamlessly integrate power analysis: Dual units, single Control for up to 16 channels

By connecting two PW8001 units with an optical cable, measured data can be consolidated in a single PW8001 in real time. The power of a maximum of 16 channels and 8 motors can be simultaneously analyzed and their efficiency and loss can be displayed and recorded with a single unit.

BNC synchronization

Electrical angle measurement function:

• Synchronized power measurement across up to 4 instruments (up to 32 channels) using BNC synchronization
• For applications requiring up to 32 channels, time-synchronized  measurement of 4 PW8001s can be done with BNC cables. (1 is the primary unit, and the 3 others are secondary.) Settings of each unit can be operated on the primary unit. Although the data is saved in each unit, they are time-synchronized for later analysis. Since the measurement-timing is synchronized, this function makes consolidation and analysis easy.
• Synchronized items
• Timing of internal operations and data-refresh
• Integration start/stop/reset
• Display hold (HOLD and PEAK HOLD) and data-refresh during hold
• Zero adjustment
• Save, copy

Use cases

Simultaneous measurement of multiple parallel inverters

Issues

Aircraft, ships, and other applications that demand a large amount of drive power sometimes distribute power using multiple inverters that are connected in parallel. When evaluating such systems as a whole, engineers sometimes wish to evaluate power of multiple inverters at the same time. However, if measurements are made separately using multiple power analyzers, the timings of measurement are not aligned making it difficult to combine the data later.

• Solution with BNC Synchronization
• When using BNC synchronization, the times at which measurement starts and stops as well as data refresh times and the current time, among other parameters, are precisely aligned, allowing data generated by separate power meters to be saved as part of a single time series.
• This capability eliminates the bothersome task of comparing data times later and makes it easy to integrate data from multiple instruments.

PMSM online parameter measurement

• Electrical angle measurement function

In order to implement fine control of a permanent magnet synchronous motor (PMSM), it’s necessary to assess the motor’s characteristics under actual operating conditions. The PW8001’s electrical angle measurement function can perform voltage and current advance measurement, which is necessary in order to implement vector control of the dq coordinate system. The instrument can calculate Ld and Lq values from electrical angle measurements and ascertain motor parameters under actual operating conditions.

Compensation of torque meter measurement error

• Dual torque value correction functions

Torque meter measurement error has a substantial impact on motor analysis. The PW8001 can perform calculations using a correction table based on user-defined values for nonlinear compensation and friction compensation. The instrument can accurately analyze high-efficiency motors as well.

Safe evaluation of increasingly high-voltage power conditioners

• 1500 V DC CAT II, 1000 V DC CAT III (When using the 2.5MS/S Input Unit U7001)

Renewable energy generation systems are being engineered to use increasingly high voltages in order to reduce equipment construction costs and transmission loss. Evaluating generation systems requires instruments that are capable of high-voltage measurement. The PW8001 Input Unit U7001 can safely measure directly input high voltages of up to 1500 V DC (CAT II) and 1000 V DC (CAT III). (The Voltage Cord L1025, which can accommodate 1500 V DC [CAT II] and 1000 V DC [CAT III], is also available.)

Analysis of power loss in reactors

• High-accuracy measurement of high-frequency, low-power-factor power

In order to improve power conversion efficiency, it’s necessary to assess power loss in reactors. The lower the reactor’s loss, the lower the power factor, making accurate measurement difficult. The U7005’s outstanding high-frequency characteristics and noise resistance make it an extremely effective tool for analyzing power loss in high-frequency, low-power-factor reactors.

Easy installation even in complicated wiring or narrow/tight spaces

The AC/DC Current Probe CT6830 and CT6831 (optional) have a compact and small-size design, making it easy to install in tight spaces around circuit boards, such as the switching power supplies inside products. Furthermore, they cover a wide operating temperature range from -40°C to 85°C, allowing for accurate measurement of low-level DC currents even in environments where the ambient temperature varies.
