Yokogawa has long been recognized as an industry standard for Motors & Drives. Yokogawa power analyzers built their reputation by providing accurate and reliable measures of speed, torque, motor output / mechanical power, synchronous speed, slip, motor efficiency, total efficiency, and many other parameters related to motor evaluation and design.
Measuring efficiency with high precision: simultaneous measurement of input and output
Preventative maintenance is crucial to maintaining reliable plant operations and reducing costly downtime. As electrical cables are found everywhere in industrial plants, insulaiton testing is one of the many active measures used in this type of periodic equipment validation. Insulation testers ensure the integrity of electrical cables by measuring the quality of the conductivity state. By diagnosing insulation quality early on, you can prevent harmful leakage currents from destroying nearby equipment or harming your personnel.

If a product uses power, then power consumption and power quality measurements must be made as part of product design and test. These measurements are essential to optimize product design, comply with standards and provide nameplate information to customers.
This article will discuss best practices for making these measurements, starting with power measurement basics and proceeding to the types of instruments and associated components typically used to make measurements. The article will conclude with real-world examples, which apply the information imparted earlier in the article to solve practical measurement problems. Although most of us have been exposed to basic power measurement equations, a primer is helpful to summarize this information and to show how it applies to product design and test.
There are several factors for a user to consider when using an IEPE accelerometer, particularly when used with newly available integrated signal conditioner/data acquisition systems. Correctly managing these factors will help the user avoid erroneous data from their IEPE accelerometer and ensure the quality of the measurement data is at the level they expect and require.
One of the main responsibilities of engineers and technicians is data analysis, and this article will show how multi-touch technologies can be used to improve the performance of this and other related tasks.
With the increased demand in electric-hybrid vehicles, the electromechanical designs of in-vehicle systems are becoming more sophisticated and there has been a demand shift towards high efficiency brushless direct current motor (BLDC) implementation. Think of motorized seat adjustment, electric window, power steering, HVAC fans, pumps, etc. In many of these systems various types of motors are used as actuators; more specifically, 3-phase BLDC motors are gaining popularity as they provide these important advantages:
How can I capture data from motion sensors synchronized with other analog data? The Yokogawa ScopeCorder series of instruments feature input modules and functions to make this possible.
How to use built-in calculations to analyze motor rotor position and find the relative angle between the rotor and sensors such as encoders or resolvers.
This white paper describes the WT1800, a precision power analyzer that has been replaced by the WT1800E, a unit with numerous improvements including better accuracy. Please visit the WT1800E product page to learn more about the WT1800E.
To keep pace with the increasing speed of switching devices in inverters, Yokogawa has developed the WT1800 precision power analyzer with 10 times faster sampling speed and 5 times wider frequency bandwidth compared with previous models. Its basic accuracy is 0.15% and the frequency bandwidth of voltage and current is 0.1 Hz to 5 MHz (-3 dB, Typical) including the DC component. With up to six inputs, a single WT1800 unit can measure the efficiency of three-phase inverters. In addition, the high-speed data capturing mode allows the WT1800 to measure transient power. This paper describes the high-speed, real-time power measurement technologies underlying these functions.
The Yokogawa DL850E is a waveform measuring and recording instrument with eight slots for signal conditioning and data acquisition modules. In addition to high-speed signal inputs up to 100 MHz sampling rate, the DL850E has features for real-time signal processing that provide advantages to scientists and engineers trying to observe complex systems.
This white paper describes the WT1600 precision power analyzer, a model that has been discontinued and replaced with the WT1800E. Please visit the WT1800E product page for more information regarding the WT1800E.
We have developed the WT1600, a high-precision, wide-bandwidth power meter. The WT1600 can measure DC and AC signals from 0.5 Hz to 1 MHz with a basic power accuracy of 0.1%. With the maximum of six input elements installed, a single WT1600 can measure the efficiency of a three-phase inverter. In addition to the functions of conventional power meters, it has wider ranges and various functions including waveform display. This paper gives an outline of the WT1600.
The accuracy of a measurement instrument varies with the range over which a reading is measured.
But what if different manufacturers specify this range differently in their instruments?
This article explores the impact of range definitions on measurement accuracy and how one can be mindful when comparing accuracy across instruments.
