WT5000具有无与伦比的精确度和模块化的构架,让工程师们能够兼顾精度与灵活性进行创新,并充满自信地将概念快速转化为产品,走向市场。
2020年3月6日,横河继续发力,为WT5000发布新功能:波形数据流输出(Data Streaming)功能选件和IEC谐波/闪变测量功能选件。详情可见横河通告。
WT5000作为世界上精度最高的精度功率分析仪,确保基本精度为±0.03%,且在选定电压和电流量程的1%~130%范围都能够保证精度。 WT5000最小化了低功率因数的影响(视在功率的0.02%),也能精确测量较大的相移与频率。
测量支持多达7个不同的功率相,采样速率达到10MS/s(18bit)。 10.1英寸的WXGA显示器具有高分辨率,允许多达7组的分屏波形显示,能显示多至12页测量参数,是效率测试的理想之选,适用于变频器驱动的电机、可再生能源技术以及诸如泵、风扇和电动车辆之类的牵引测量。测量数据还会即时以矢量格式或趋势图显示。
Use of the internal DC power supply for AC/DC current sensors simplifies the preparations before measurement and the measurement setup only requires the current sensor and a connecting cable. Using an external DC power supply and additional wiring is no longer required. There are three sensor connection cable lengths available; i.e., 3 m, 5 m, and 10 m.
*Firmware version 3.01 or later is required.

WT5000支持独立的触屏和硬件按键操作,流畅直观的体验让连接、配置和测量比以往更简单。 10.1英寸的WXGA触屏即使在电机和变频器等高噪音环境中依然保持优秀的抗干扰能力。
The operability of the touch panel has been improved. "Time / div" can be set by pinch / out. Also, you can flick the waveform display contents.
除了低通频率滤波器和线路滤波器, WT5000还具备高级滤波功能,提供前所未有的控制来精确分析最复杂的波形。
评估和对比变频器、电机或功率调节器高达500次的输入输出谐波。 WT5000让用户不仅能同时测量谐波和功率,还能对比来自两个不同输入源的谐波。
由于采用了具备数字并行通路技术的抗混叠功能和线路滤波器,可以同时对宽频成分和窄频成分进行功率分析,所以最大程度地降低了噪音和混叠的影响。
Combined with the /G7 option and IEC Harmonic /Flicker measurement software, the WT5000 measured harmonic data can be saved into a PC and tested according to IEC regulations. To support large equipment over 16 A/phase (IEC61000-3-12) the CT200 current sensor model can be used.
The waveform data is streamed without any gaps up to 2 MS/s and is synchronized with the numerical data. Abnormal findings in numerical data can be directly linked and be evaluated in the waveform data. For example, one can find numeric parameter variations caused by the influence of imposed high-frequency noise.
根据应用需求定义和使用事件触发及自定义运算。事件触发功能允许用户设置限值,捕获特定功率、电流或其他参数限值内或限值外的读数。用户还可以定义和使用多达20条不同的表达式,进行自定义运算。满足触发条件的数据可被存储、打印或另存到USB存储设备。
用户自定义功能
This feature can follow fluctuating input frequencies without gaps by changing the data update rate automatically when measuring devices like motors whose input signal frequency fluctuates with changes in rotation speed. It can cover from frequencies as low as 0.1Hz. In addition to constant-interval update mode of 10ms-20s, “Auto update mode”, which updates data in sync with the cycle of input signal, is now available. This new feature is useful for continuous measurement, such as automated testing.
Current range, various filters, data update rate, and measurement period can be automatically switched according to the measurement scene.
The measurement scene can be selected from among "50/60Hz," "DC," "PWM," "High Frequency," and "General.
After the automatic setting, the switched items can be checked at a glance and the settings can be easily adjusted.
When three-phase delta wiring is used, the results of converting to phase voltage using delta-star conversion can be used to measure harmonics, display waveforms on screen, and output data. (When using star connections, it is possible to measure harmonics using the result converted to line voltage using star-delta conversion.)
It can calculate the fundamental wave components of phase voltages required for measuring motor parameters (Ld, Lq), and can be used to evaluate synchronous motors.

Measuring transformer loss helps ensure safer operation and optimizes delivery of electricity. During testing, low power factor signifies high core losses and requires specialty instruments to more accurately measure power.
Maximum torque per ampere (MTPA) is an optimization strategy for the control of electric motors and drives that employ field-oriented control (FOC), particularly with electric vehicles (EVs) and industrial automation applications. The goal of MTPA is to achieve the maximum possible torque output from a motor for a given current input.
Maximum power point tracking (MPPT) charge controllers play a crucial role in the optimization of renewable energy system efficiency and performance. Through dynamic tracking of a renewable energy source’s maximum power point, an MPPT controller enables more efficient energy harvesting, faster charging, and adaptability to changing environmental conditions.
Energy consumption in low-power and standby modes is an important issue due to increased awareness that energy resources are becoming limited and demand for energy-saving household electrical appliances continues to grow. IEC62301 Ed2.0 (2011) and EN 50564:2011 define standby mode as the lowest energy consumption of an appliance not performing its main function, when connected to the mains. IEC62301 Ed2.0 (2011) defines test methods and requirements for both the mains supply and the test equipment. It is crucial that design and test engineers choose highly accurate power measurement tools to confirm that their devices meet these requirements.

高精度功率分析仪WT5000产品介绍
Test and measurement engineering work groups can have differing priorities and requirements, which often results in multiple instrumentation systems and data file formats, as well as incompatible reporting. This lack of effective communication between groups and instruments causes decreased efficiency and quality and increased spending and time to market. Unify test and measurement instrumentation, software, and data across engineering teams with a suite of solutions that caters to the different needs of engineering work groups, including accurate power data, fast sampling rates, long recordings of multiple different input types, and insights into waveform data.
The current sensor element for the Yokogawa Test&Measurement WT5000 Precision Power Analyzer is ideal for applications requiring a current transformer for high-current measurements. The internal DC power supply simplifies preparations before measurement, requiring only a connecting cable and eliminating the external power supply.
The WT5000, an industry-leading power analyzer, features seven field-removeable elements, 10 MS/s, 1 MHz power bandwidth, 18-bit resolution, and 0.03% basic power accuracy. Yokogawa Test&Measurement continues to innovate on the platform, enabling /D7 data streaming, /G7 harmonics, and flicker analysis.
The new current sensor element replaces the traditional current inputs and includes a sensor input terminal with integrated ±15V power supply, eliminating the need for an external power supply. The isolated voltage terminals remain the same as the 5A and 30A elements.
This video demonstrates how to test to an IEC standard (IEC 61000) using a Yokogawa Test&Measurement WT5000 Precision Power Analyzer and the harmonic flicker testing software. The software automates the process of judging if the device under test is compliant with the chosen standard and allows you to output the necessary test reports for your records.
With ongoing innovations in motor and inverter technologies seeking to advance global decarbonization objectives in the automotive industry, it’s crucial that engineers have a thorough understanding of how to properly analyze these systems.
