Yokogawa’s WT5000 Precision Power Analyzer has won the prestigious “Power Product of the Year” trophy at the second annual Electronics Industry Awards.
The award was presented on the 21st June at a ceremony at London’s Tower Hotel in the presence of an audience of leading industry professionals and has become a highlight of the industry calendar since its inception in 2018, where leading figures from the electronics field gather to celebrate their achievements and reward the market leaders from across the blossoming sector.
Commenting on the win, editor of CIE magazine, Niamh Marriot, said: “Ensuring your product is safe with great efficacy is paramount for our industry. Testing equipment and products and ensuring their accurate readings and measurements is vitally important, as it can be dangerous if not done correctly, and the precision of the product guarantees this level of accuracy and thereby enhances safety.”
“The Yokogawa product is precise and well thought-out, and all round is an excellent design that works”, she added: “Congratulations to Yokogawa!”.
Kelvin Hagebeuk, European Marketing Manager, Yokogawa Europe Test & Measurement, said “The Yokogawa community of precision makers is very excited and most of all honoured to win this prestigious award. For us at Yokogawa the WT5000 Precision Power Analyzer is the leading building block in our mission to enable customers to develop zero emission technologies. A mission which ultimately provides a sustainable future for generations to come.”
“The electronic industry is best equipped and positioned to directly influence a sustainable usage of energy resources”, he added: “The awards scheme recognises good work, which is inspiring and energising to all involved especially the innovative and highly skilled precision engineering team."
The event was organised by Datateam Business Media and was hosted by comedian Ian Moore and household favourite Alan Dedicoat.
About the WT5000 Precision Power Analyzer
The new Yokogawa WT5000 is the first of a new generation of Precision Power Analyzer that offers exceptional measurement accuracy of ± 0.03% combined with stability, noise immunity and plug-in modular flexibility to meet the measurement needs of today’s developers of energy-efficient systems.
In rapidly evolving industry sectors like electric vehicles, renewable energy and energy efficient technologies, the need for reliability in testing to enhance safety, efficiency and performance has never been greater. Changing application needs and evolving international standards call for custom measurements and consistent accuracy, and in the WT5000 Precision Power Analyzer, engineers have a versatile platform that not only delivers reliable measurements today, but is ready for the challenges of tomorrow.
The WT5000 achieves the world’s highest measuring accuracy: ±0.03% of total at 50/60 Hz. As a result, it has become possible to evaluate the power consumption, loss, and efficiency of electrical and electronic devices. In particular, its wide dynamic current range is indispensable for tests on energy-saving designs.
One of the essential elements for determining the performance of a power measuring instrument is the A/D converter that performs analogue-to-digital conversion. In order to obtain the world’s highest measurement accuracy, the WT5000 uses an 18-bit converter with a sampling frequency of maximum 10 MS/s. As a result, it becomes possible to accurately capture waveforms from the latest high-speed inverter devices. It is very effective for stable measurement results.
While the WT5000 has the same dimensions as existing models in Yokogawa’s WT series, it incorporates up to seven input channels, allowing it to support applications that previously could only have been measured by synchronising several separate instruments. As a result, it offers considerable savings in installation space, communications overheads and cost-effectiveness. Further benefits result from the use of plug-in modular input elements, which can be swapped directly by the user.
The 30 A and 5 A elements, for example, can be switched for applications involving electric vehicles or fuel-cell vehicles, where developers are increasingly required to evaluate a number of different motors. Using the WT5000 equipped with the /MTR1 and /MTR2 options, it is possible to evaluate up to four motors simultaneously with one unit. Since these options allow the input of four channels, flexible measurement of the A, B, C and Z phases of each motor can be carried out.
With a 7 elements input capability, multi-system measurement is increased in harmonic measurements on 3-phase systems, for example. The WT5000 can carry out two harmonic measurement functions simultaneously, each at up the 500th order and up to 300 kHz fundamental waveform. This makes it possible to measure the carrier frequency component from the rotational speed of the motor in the inverter drive and also to check the influence of the carrier frequency on the motor drive.
An increasing number of applications require the evaluation of larger-current devices, typical examples being electric vehicles and large-scale solar installations. In these cases, external current sensors are often used. An external current sensor input function is fitted as standard in the input element of both the 30 A and 5 A input elements of the WT5000. For much higher currents (up to 2000 A RMS) dedicated high-current sensors are available. Yokogawa AC/DC current sensor CT series is current output type in order to prevent noise influence.
Yokogawa, the world's largest manufacturer of energy and power analyzers and meters, provides a broad choice of digital power analyzers to satisfy all requirements.
The WT5000 Precision Power Analyzer is a versatile platform that delivers reliable measurements.
