HIOKI POWER ANALYZER
HIOKI POWER ANALYZER
Model: PW8001
Brand: Hioki
Origin: Japan
概要
DC, 0.1 Hz to 5 MHz, 3-phase 4-wire, High Precision Power Analyzer for Motor and Inverter Efficiency Analysis
The PW8001 sets a new benchmark for complete power analysis solutions with Hioki being the only manufacturer that offers industry-leading power analyzers and a wide portfolio of high-accuracy current sensors both developed and manufactured by Hioki. This enables to align their performance and results in more accurate and stable measurements from DC to high frequencies and low power factor measurements thanks to functions like the automatic phase shift correction.
Upcoming industry challenges are anticipated with the ability to measure even large currents at voltages up to 1500 V, 15 MS/s sampling rate and multi-channel measurement target applications using SiC/GaN semiconductors from automobile electrification, smart grids and reactors to renewable energy supply sources.
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% (*1)
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.
Accurate capture of power fluctuations caused by high-speed switching
- Sampling performance 18-bit, 15 MHz (*1)
- Noise Resistance (CMRR) 110 dB, 100 kHz* (*1)
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.
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.
PMSM online parameter measurement (*2)
- 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 (*2)
- 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 (*3)
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.
