High performance power analyser

Yokogawa Test & Measurement Corporation announces the release of the WT1800R series high performance power analyser to boost the efficiency of complex power measurements for new energy applications.

The WT1800R combines high and low current input elements, supported by a power supply for current sensor, to verify the efficiency and power consumption of a wide range of applications.

The WT1800R power analyser was designed to support the development and production of high efficiency new energy technologies, combining measurement results with waveform capturing instruments through the IS8000 software. In addition, this allows engineers to perform field-oriented control measurements such as Vd/Vq and Id/Iq and store the measurement data directly to a network drive.

Whether analysing multiphase inputs during motor and drive design or meeting the stringent efficiency standards of photovoltaic inverters, the WT1800R provides the versatility to help engineers bring their product concepts successfully to market with an easy-to-read colour scheme.

The WT1800R is the only instrument in its class that guarantees a power accuracy of 0.05% of reading plus 0.05% of range and is capable of harmonics analysis up to the 500th order of a 50/60 Hz fundamental frequency.

The stability of the WT1800R ensures that precision measurements can be made today and over the long term. The basic power (AC measurement) accuracy of the WT1800R 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 from the low power factor error of ±0.07% of apparent power.

With simultaneous 16bit measurements on up to 6 input channels at 2 MS/s, a wide range of display and analysis features through an enhanced display, and PC connectivity, the WT1800R is suitable for a broad range of power efficiency and harmonic analysis requirements.
