Richiedi Informazioni

Con la crescente attenzione verso la generazione e la conversione dell’energia in modo più efficiente, l’uso di fonti rinnovabili come il solare e l’eolico è in continua espansione. Parallelamente a queste tendenze, i rapidi progressi nei veicoli elettrici e nelle tecnologie ad alta efficienza energetica rendono essenzarie misurazioni precise per rilevare anche le più piccole perdite di energia. Che si tratti di analizzare ingressi multifase durante la progettazione di motori e azionamenti o di rispettare rigorosi standard di efficienza per gli inverter fotovoltaici, l’analizzatore di potenza ad alte prestazioni WT1800R offre agli ingegneri uno strumento preciso e affidabile per misurare potenza, qualità ed efficienza.

 

6 Inputs on a High-Resolution Display

Make simultaneous measurements on up to 6 inputs at 2 MS/s (16 bits). The high-resolution 8.4 inch XGA display allows split-screen viewing up to 6 waveforms and can display up to 12 pages of diverse measurement parameters, making it ideal for efficiency tests of inverter driven motors, renewable energy technologies, and traction applications like pumps, fans, and hybrid/electric vehicles. The unit can also display measurements in vector format or trended over time.

Guaranteed Accuracy Across a Wide Range of Conditions

Accurately measure a wide range of voltage, current, and frequency conditions. Basic power (AC measurement) accuracy is guaranteed between 1% to 110% of the selected voltage and current range, which equates to voltages from 15 mV to 1100 Vrms and currents from 0.1 mA to 5.5 Arms (for a 5 A input element) and 10 mA to 55 Arms (for a 50 A input element). The unit is also accurate during large phase shifts and high frequencies thanks to minimized influence of low power factor error (±0.07% of apparent power).

Two Types of Input Elements

Both 5 A and 50 A input elements can be installed in a single unit. This enables engineers to use a single WT1800R for multiple applications such as standby power measurement and the evaluation of various operating modes of the device under test.

Flexible and Automatic Data Updates

Manually set measurement intervals with 9 data update intervals between 50 ms to 20 s or follow fluctuating input frequencies by changing the data update rate automatically. This is useful when measuring devices like motors, where input signal frequency varies with RPM. In addition, during low-speed operation (when the input frequency is 20 Hz or less), data updates every cycle, which is helpful when checking measurement results per motor revolution.

Harmonic Analysis

Analyze harmonics up to the 500th order for a 50/60 Hz fundamental, even with a data update interval of 50 milliseconds. The WT1800R features two options for analyzing harmonics in addition to power parameters:

  • Harmonic measurement mode (/G5 option) for fundamental wave, harmonic components, and total harmonic distortion (THD)
  • Dual harmonic option (/G6 option) for side-by-side measurement of harmonics on two different sources (e.g., input and output of inverters, variable speed motors, lighting ballasts, UPS, etc.)

Motor Evaluation Function

Measure more than just electrical parameters, the motor evaluation function enables measurement of rotation speed and direction, torque, mechanical power, synchronous speed, slip, electrical angle, motor efficiency, and total system efficiency from the analog or pulse outputs of rotation and torque sensors.

Measurement for Field-Oriented Control

Permanent magnet synchronous motors (PMSM), which offers the highest efficiency compared to other motor types, are generally controlled using dq-axis parameters (a rotating coordinate system). The WT1800R has enhanced calculation functions that enable computation of Ld and Lq and support measurements required for PMSM control.

DC Power Supply for AC/DC Current Sensors (/PD2 Option)

The WT1800R can be equipped with a DC power supply for the CT series of AC/DC current sensors to measure large currents and improve S/N ratio and noise immunity.

High-Speed Data Capture

The high-speed data capturing function measures Sigma-Urms, Sigma-Irms, and Sigma-P from DC signal and three-phase devices every 5 ms when external synchronization is OFF or 1 ms to 100 ms when external synchronization is ON, depending on the frequency of the clock signal.

Easy-to-Use Custom Display with Internal Storage

Customized screens allow for visual confirmation of parameters and can be quickly loaded from the internal storage for easy display.

The built-in memory can also be used to store numerical data and other data. Capacity is 1 GB.

 

Correlate Power Consumption and Inverter Waveforms

When efficiency deterioration is observed during motor endurance tests, combining high-precision power and waveform measurements can help identify the cause. Yokogawa’s integrated measurement software platform, IS8000, enables simultaneous display of high-precision power measurements from the WT1800R and waveform data from the DL950 high-speed data logger or DLM5000 oscilloscope. This setup allows for easy, on-screen analysis and correlation between power consumption and inverter waveforms.*1
