Measuring transformer loss helps ensure safer operation and optimizes delivery of electricity. During testing, low power factor signifies high core losses and requires specialty instruments to more accurately measure power.

概览:

Maximum torque per ampere (MTPA) is an optimization strategy for the control of electric motors and drives that employ field-oriented control (FOC), particularly with electric vehicles (EVs) and industrial automation applications. The goal of MTPA is to achieve the maximum possible torque output from a motor for a given current input.

概览:

Maximum power point tracking (MPPT) charge controllers play a crucial role in the optimization of renewable energy system efficiency and performance. Through dynamic tracking of a renewable energy source’s maximum power point, an MPPT controller enables more efficient energy harvesting, faster charging, and adaptability to changing environmental conditions.

概览:

Energy consumption in low-power and standby modes is an important issue due to increased awareness that energy resources are becoming limited and demand for energy-saving household electrical appliances continues to grow. IEC62301 Ed2.0 (2011) and EN 50564:2011 define standby mode as the lowest energy consumption of an appliance not performing its main function, when connected to the mains. IEC62301 Ed2.0 (2011) defines test methods and requirements for both the mains supply and the test equipment. It is crucial that design and test engineers choose highly accurate power measurement tools to confirm that their devices meet these requirements.

    高精度功率分析仪WT5000产品介绍

    概览:

    Test and measurement engineering work groups can have differing priorities and requirements, which often results in multiple instrumentation systems and data file formats, as well as incompatible reporting. This lack of effective communication between groups and instruments causes decreased efficiency and quality and increased spending and time to market. Unify test and measurement instrumentation, software, and data across engineering teams with a suite of solutions that caters to the different needs of engineering work groups, including accurate power data, fast sampling rates, long recordings of multiple different input types, and insights into waveform data.

    概览:

    The current sensor element for the Yokogawa Test&Measurement WT5000 Precision Power Analyzer is ideal for applications requiring a current transformer for high-current measurements. The internal DC power supply simplifies preparations before measurement, requiring only a connecting cable and eliminating the external power supply.

    The WT5000, an industry-leading power analyzer, features seven field-removeable elements, 10 MS/s, 1 MHz power bandwidth, 18-bit resolution, and 0.03% basic power accuracy. Yokogawa Test&Measurement continues to innovate on the platform, enabling /D7 data streaming, /G7 harmonics, and flicker analysis.

    The new current sensor element replaces the traditional current inputs and includes a sensor input terminal with integrated ±15V power supply, eliminating the need for an external power supply. The isolated voltage terminals remain the same as the 5A and 30A elements.
