Measurements

EMC test and PowerQuality

Measurements

Electromagnetic compatibility (EMC) is an important objective when planning and operating electrical equipment. All components should work smoothly with each other and then only intentionally interact with each other, if at all. Unfortunately, this is sometimes very difficult to achieve in practice. In order to be capable of mitigating PowerQuality problems such as harmonics, voltage dips or reactive powers effectively, the sources of error must first be analysed and the measurements evaluated.

REO provides you with the necessary portable or permanently installed measurement devices and records measurement data, if necessary, for up to one year. Finally, our qualified professionals evaluate the recorded measurements, thereby enabling them to put together the appropriate REO PowerQuality product for you individually.

Our test fields

Quality assurance is top priority at REO. That is why we keep test fields at all our locations worldwide as part of our comprehensive product control during operations. The latest measurement technology, which is always kept state-of-the-art, ensures that the products delivered have the highest quality.

According to the principle of “everything from one source”

Precise understanding of the problem with the help of EMC long-term measurements (over several months) using REO devices
Uniform compliance with applicable norms and standards
Custom design of a product or a combination of products
In-house development and manufacture of the solution
On-site installation and servicing by a qualified REO employee

Which product solution is right for me?

A custom-designed product solution is determined using long-term EMC measurements (REO Service). These measurements show details over several months or even down to a fraction of a second.

There are a variety of options depending on your requirements (THDI value), the legal standards and specifications:

For example, if the THDI value is set to 35%, then a mains choke is suitable. The advantage of this solution is very clearly on the relatively low-cost implementation.
For a THDI value set to 20%, we would already use a mains choke combined with a filter.
The REOWAVEpassive is an ideal solution for a low THDI value of less than 5%.A B6-inverter topology is required for this.
