Unexplained faults, faltering control systems or machines that suddenly shut down. In modern, complex electrical installations, the cause is often not visible to the naked eye. The problem lies in the interaction between your equipment: electromagnetic compatibility (EMC).
At HyTEPS, we understand that what you need is not theoretical reports, but a working installation and business continuity. We offer you assurance in every kilowatt. Our engineers analyse the situation on site, find the source of the failure and ensure that your processes continue to run uninterrupted. Where others stop at supplying components, we take responsibility for diagnosis and solution.
EMC stands for Electromagnetic Compatibility. In understandable language, this means: the ability of electrical devices to continue working properly in close proximity to each other, without interfering with each other.
You can compare your electrical installation to a busy traffic square. If everyone obeys the rules, traffic flows smoothly. But if one vehicle (device) makes unexpected manoeuvres or produces too much noise, chaos ensues and others get stuck. In your installation, this 'noise' is electrical noise that distorts signals.
Technically, EMC is all about the balance between two factors:
When emissions are too high or immunity is too low, problems arise. We call this Electromagnetic Interference (EMI). Unfortunately, the result is tangible for your organisation: outages, damage, data loss and unsafe situations.
EMC problems are notorious for often being erratic and difficult to reproduce. One day everything runs perfectly, the next day a crucial production line shuts down for no apparent reason.
Do you recognise one or more of the following symptoms?
If you ignore these signals, you risk not only costly downtime, but also unsafe situations for your employees. A machine that wrongly ignores or activates a safety stop poses an immediate risk.
We regularly hear from technical managers, "We didn't used to have this problem, did we?" That's right. Today's electrical installation is fundamentally different from that of 20 years ago.
The energy transition and the need to save energy have changed the nature of connected equipment. Whereas we used to have mostly 'linear' consumers (such as light bulbs and directly switched motors), we now use power electronics en masse. Think frequency converters, LED drivers, EV charging posts, solar panel inverters and UPS systems.
These modern devices switch power on and off thousands of times per second to operate efficiently. This switching behaviour creates high-frequency pollution on your power grid. At the same time, modern control electronics are becoming more sophisticated, compact and energy-efficient (lower voltages), making them actually more sensitive to this same pollution (lower immunity).
So we are seeing an increase in 'polluters' as well as an increase in 'sensitive receivers'. In this complex environment, blind reliance on the CE marking of individual devices is no longer enough. It's all about total system integration. This is precisely where HyTEPS' expertise lies
Installing filters haphazardly or replacing cables is rarely the structural solution and is unnecessarily costly. HyTEPS takes a data-driven approach. We do not guess, we measure.
Our specialised engineers come to your site with high-end measurement equipment. We do not limit ourselves to a standard measurement, but look deep into the installation for high-frequency disturbances, transients and common-mode currents. We map the true 'blood flow' of your installation.
The data gathered is analysed by our specialists. Is it an earth fault? Is there internal crosstalk? Or is a specific drive causing interference? If necessary, we use simulation models to test the impact of possible solutions in advance. You receive a clear report with concrete conclusions, not vague technical jargon.
Based on the analysis, we implement the right solution. This can range from installing active filters to adapting cabling. After implementation, we always perform a validation measurement. This is how we prove that the problem has been solved and guarantee your operational reliability.

Power Quality deals with the quality of the power supply up to frequencies of about 2.5 kHz (harmonics, dips). EMC (Electromagnetic Compatibility) is about disturbances in much higher frequencies (kHz to MHz) that interfere with communications and electronics. HyTEPS measures both.
At extremely high field strengths, electromagnetic fields can affect the human body, but in standard situations within industry the main concern is danger to machines and processes. Indirectly, EMC can indeed be dangerous for people: if a safety circuit, crane control or medical equipment fails due to a malfunction, direct safety risks arise.
This is a common misconception. A CE mark means that the device has been tested under specific, isolated lab conditions. But once you combine dozens of these devices in one installation, with long cables and other 'pollutants', the limits can still be exceeded. The sum of the parts then creates the problem. CE is a starting point, not a guarantee of a fault-free installation.
Costs depend on the size of your installation and the complexity of the problem. A targeted measurement at one machine is different from a complete scan of a hospital or data centre. However, consider it an investment: one day (or even one hour) of production downtime often costs many times more than a specialist investigation. We always make a clear price agreement in advance.
Meters can be bought for basic Power Quality measurements, but EMC measurements require specialist high-frequency measuring equipment and antennas. Even more important is the knowledge to interpret the measurement data. A graph says nothing if you don't know what the physical cause is. Our engineers are specifically trained for this.
Yes, harmonics are distortions of the sine wave form with a multiple of the fundamental frequency (50Hz). They fall under the heading 'Low-frequency EMC'. They often cause overheating of transformers, cables and neutral conductors. HyTEPS specialises in reducing harmonics with active filters.
Don't wait for plant downtime. Call us in when there are unexplained malfunctions, frequent electronics failures, or preventively when you are planning a major expansion with power electronics (such as heat pumps, solar panels or EV chargers). A 'zero measurement' beforehand prevents a lot of misery and costs afterwards.
We work in every sector with critical, complex electrical installations. From heavy industry, data centres and hospitals to marine and offshore. Wherever electricity reliability is crucial and failure is not an option, we feel at home.
Conducted fault moves through the cables (copper). This can be via the phases, neutral or earth. Radiated interference travels through the air (radio waves/electromagnetic fields). Both types require different measurement methods and solutions. HyTEPS examines both paths during an analysis.
We usually install measuring equipment that collects data over a period of time (e.g. a week or two weeks) to catch even occasional failures. For acute problems, our engineers can often take measurements directly on site to find the hotspots.
Don't let invisible failures rule your process. Our engineers are ready for a clear diagnosis.
