Description
The WT1800E is a high-performance power analyzer that guarantees power accuracy of 0.05% of reading plus 0.05% of range. It is capable of harmonics analysis up to the 500th order of a 50/60 Hz fundamental frequency. With up to 6 input channels, a wide range of display and analysis features, and PC connectivity, the WT1800E is the ideal tool for engineers to accurately measure power characteristics and efficiency of electrical devices.
- Basic power accuracy:
- 0.05% of reading
- 0.05% or range
- Harmonics analysis up to the 500th order of a 50/60 Hz fundamental frequency
- Up to 6 input channels at 2 MS/s (16 bits)
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 of the WT1800E allows split screen viewing of 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 trending in time.
Guaranteed accuracy across a wide range
Measure accurately at a wide range of voltage, current and frequency conditions. The basic power accuracy of the WT1800E is guaranteed between 1% to 110% of the selected voltage and current range. This equates to voltages from 15 mV to 1100 V rms and currents from 0.1 mA to 5.5 A rms (for a 5 A input element) and 10 mA to 55 A rms (for a 50 A input element). The unit is also accurate during large phase shifts and high frequencies thanks to the minimized influence of the low power factor error (±0.07% of apparent power).
Range configuration
Track signal changes faster by eliminating unnecessary range changes. The WT1800E’s range configuration function allows users to select input ranges based on their specific use cases so that optimal range settings are achieved quicker. This reduces the time during repetitive production tests, such as setting to OFF, 100 V, OFF and so on, which is performed frequently on the production line.
Harmonic analysis
Analyze harmonics up to the 500th order for a 50/60 Hz fundamental even at a data update interval of 50 milliseconds. The WT1800E 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 for example input and output of inverters, variable speed motors, lighting ballasts, UPS, etc.
Power integration and auto ranging
Measure energy bought/soldn grid connections or charged/discharged in batteries. The WT1800E’s Power integration function integrates instantaneous values for both positive and negative readings. It also measures total energy (Wh) and current (Ah) when load conditions vary widely such as in devices transitioning from standby to operation mode. Should an input signal start to fall out of the expected range, this function can automatically adjust the range while continuing to integrate the measured values.
High-speed data capture
The high-speed data capturing function can measure Sigma-Urms, Sigma-Irms, and Sigma-P from DC signal and three phase devices every 5 ms when External Synchronization is OFF. It can also update at 1 ms to 100 ms when External Synchronization is ON depending on the frequency of the clock signal.
Flexible & automatic data updates
Manually or automatically set measurement intervals. The WT1800E offers 9 data update interval between 50 ms to 20 s but can also follow fluctuating input frequencies by changing the data update rate automatically. This is useful when measuring devices like motors whose input signal frequency varies with RPM.
DC power supply for AC/DC current sensors (/PD2 option)
The WT1800E can be equipped with a DC power supply for the CT series of AC/DC current sensors. By using dedicated connection cables and shunt resistors, the WT1800E can measure large currents. Improved S/N ratio and noise immunity is achieved by connecting the sensors in this way.
* /EX1 to /EX6 option must be installed in the WT1800E to be able to use the Shunt Resistor Box.
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.
761941 WTViewerE Application Software for WT3000E/ WT3000/ WT1800E/ WT1800/ WT500/ WT300E/ WT300
WTViewerE software enables PC connectivity for Yokogawa power analyzers such as the WT3000E, WT1800E, WT500 and WT300E through Ethernet, USB, GPIB or RS232. This connectivity allows users to easily control, monitor, collect, analyze, and save measurements remotely.
WTViewerEfree application software
Easily view, control and download measurements from your PC. The WTViewerEfree is free software that connects the WT1800E to a PC via a communications interface making numeric, waveform, trend and harmonic data easily accessible via PC.
User-defined events and computations
The event trigger function of the WT1800E allows users to set limits for the capture of readings that fall into or out of a specific range of power, current or other parameters. Data that meets the trigger conditions are stored, printed, saved to a USB memory device etc. Users can also define and use up to 20 expressions for custom calculations.
