ZES ZIMMER LMG610 German Gaomei GMC-I Power AnalyzerEstablish a benchmark for power analysis
For the past thirty years, ZES ZIMMER has only focused on high-precision power measurement technology, so we know that this is not just about
Simple measurement of voltage and current. Anyone attempting to measure power using a general data collection system will quickly need to face its limitations:
How is the common mode rejection situation? Is the test result still reliable when the power factor is 0.01? Is the ground capacitance small enough to resist
Interference from leakage current? In which frequency range does the manufacturer guarantee the measurement accuracy stated? It can be quickly and clearly understood that only specific skills are targeted
Only equipment designed for rate measurement can truly meet these high requirements. ZES ZIMMER's LMG670 stands out in the market because
It has extremely high reliability, precision, and maximum bandwidth - all of which are achieved throughexcellentIdeal conditions for the outcome.
Multiple channel combinations suitable for various applications
The power analyzer provides different accuracy levels, allowing users to choose the appropriate instrument to complete their work. After all, not all applications
NeedtallThe precision. Usually, a normal resolution and accuracy are sufficient. Unfortunately, not all measurement applications are like this.
The following situation often occurs: different measurement points require different bandwidths and accuracy levels under the same measurement configuration. Why is this
LMG670 offers three different input modules that can be installed in the same main chassis to ensure that you can customize the measuring instruments needed for your specific application. This low-priced solution can also meet your requirements well without compromising on accepting low precision
Degree or overuse.

Simultaneous measurement of two bandwidths, thanks to dual paths - no compromise, beyond doubt
In traditional power analyzers, the measured signal is first subjected to analog processing, and then converted into a digital signal through an A/D converter for processing, resulting in
The signal can be measured across the entire frequency range, and can also be used as the basis for FFT analysis or further digital filtering through anti aliasing filters.
Due to the limitations of A/D converters, some of their inherent drawbacks will be introduced into traditional devices. If the filter is turned on for measurement
To avoid confusion in FFT analysis, wideband values are discarded. If the filter is turned off, strictly speaking, FFT should not be used. If resistance is not used
The confusion filter performs FFT analysis on the entire frequency range, and the calculated values are suspicious, with a confusion error of up to 50%. For example, it is easy to find that there is none
How can at least 0.5% deviation be ignored. Finally, the validity of the results is also questionable when alternating between filtered and unfiltered measurements
Because this assumes that the signal does not change over time, which is almost non-existent in reality. In addition, this processing procedure is particularly
Other time-consuming activities.
Finally, all proposed measurement methods are merely unsatisfactory compromise solutions. That's why ZES ZIMMER is fundamentally
Design a dual path architecture for signal processing and research and development. Simulation processing is the same as traditional measuring instruments, but subsequent digital processing has been thoroughly implemented
Bottom change. LMG670 is a power converter with two A/D converters in each voltage and current channel in two independent signal paths worldwide

In order to clarify the functional relationship between physical measurement channels correctly, the power measurement channels (P channels) can be grouped into so-called groups, which are generally
Present as a virtual measurement channel or virtual device outside of the physical channel. The logical combination of P channels depends on the number of connections and phases of the analyzed system.
Due to the flexibility of LMG670, it can even be assembled into unusual and rare configurations, such as phase separated systems and four phase or multi-phase systems, which are both simple and
Reliability, the requirement is that all channels in the same group have the same fundamental frequency and are the same module (A1, B1, C1). this
It will avoid minor errors caused by different technical performance of different module types. One benefit of creating a group is that it changes the settings of the instrument
It should be simple, for example, to make the filter settings that affect all channels within the same group only need to be set once. In addition, derived values such as within the group
The active, apparent, and reactive power of all channels are calculated. When grouping specifies how channels are logically connected, the wiring will specify the measuring equipment

In order to provide aessenceThe answer requires continuous execution of two independent tasks
Measurement: One is the unfiltered wideband power, and the other is the power of the filtered signal at a specific frequency. Then use FFT analysis to measure the harmonic spectrum. This process is very time-consuming, but it cannot guarantee that the initial measurement state will remain unchanged.

The total loss is related to frequency and should be minimized as much as possible, as they have a significant impact (such as in the battery range of electric vehicles).
The power loss of the magnetic core can be directly calculated from the excitation current of the tested coil and the induced voltage of the induction coil. The magnetic flux density of magnetic core materials can be obtained from
The rectified value of the induced voltage of the induction coil is derived. The magnetic field strength is proportional to the current flowing through the tested coil.

In order to reduce energy consumption, light bulbs are being replaced with more efficient light sources around the world. Although the necessary operation on the consumer side is only to insert a new product into an existing device, the electrical level difference is actually very large - compared to traditional light bulbs, LED lights, and compact fluorescent lamps
Low energy bulbs are controlled by special electronic ballasts. Some ballasts operate at switching frequencies up to 200kHz, resulting in signal distortion frequencies of up to 1MHz. The first thing manufacturers must do is to prevent damage to the feedback circuit, followed by ensuringgoodThe lifespan of the product. in order to

CE compliance testing for harmonics and flicker
If electrical equipment, systems, and devices are to be placed on the EU market, their electromagnetic emission and immunity must meet the levels allowed by EU directives and regulations. Two different types of power grid emissions were tested: harmonics and flicker. Any device with nonlinear loads will generate harmonics. from
Due to the impedance of the power grid, this will cause voltage download and distortion. In addition, certain devices (such as continuous heating equipment, heating furnaces, etc.) control power consumption by suddenly opening and closing, which can cause instability in the grid level due to the impedance of the grid. This generates voltage fluctuations, causing electrical problems
