New series high performance power analyser released

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

The series 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.

Since 2011, the WT1800 series has been a choice for power and efficiency measurements with excellent performance and long-term stability. With the latest power analyser, engineers can continue to perform reliable measurements, combine these measurements with the results from other measurement instruments, and perform field-oriented control measurements on motors and drives.

The analyser was designed to support the development and production of new high-efficiency energy technologies, combining measurement results with waveform capturing instruments through the IS8000 software. Also, this enables 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 device provides the versatility to help engineers bring their product concepts successfully to market with an easy-to-read colour scheme.

The device is the only instrument in its class that ensures 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 50/60Hz fundamental frequency.

The stability of the device ensures that precision measurements can be made today and over the long term. The basic power (AC measurement) accuracy of the series is guaranteed between 1% to 110% of the selected voltage and current range which equates to voltages from 15mV to 1100Vrms and currents from 0.1mA to 5.5Arms (for a 5A input element) and 10mA to 55Arms (for a 50A 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 16-bit measurements on up to six input channels at 2MS/s, a wide range of display and analysis features through an enhanced display, and PC connectivity, the WT1800R is suited for a wide range of power efficiency and harmonic analysis requirements.
