You are investing in the future. Solar panels on the roof, charging stations in the car park and heat pumps in the technical area. These steps are necessary for your operations, your image and the climate. But there is a downside that often goes unexposed in the plans of architects and installers. At the same time, the technology that makes us sustainable places a heavy burden on the quality of voltage and current within your own walls.
HyTEPS ensures that your electrical installation can cope with this transition. We offer the expertise to identify, simulate and definitively resolve risks. In this way, we guarantee continuity and safety exactly where it is critical for you.
The energy transition is forcing organisations to electrify. You replace traditional, fossil-based processes with electrical alternatives. This leads to a radical change in the structure of your electrical installation. Where linear loads (such as light bulbs and directly switched motors) used to be the norm, power electronics now dominate. This entails a fundamental change in the physics of your power grid.
Think of the inverters in your PV plant, the variable speed drives in your heat pumps and the rectifiers in EV chargers. These devices are highly efficient, but they work by 'chopping' alternating current into pieces to create the desired frequency or voltage. This switching process inevitably causes side effects: harmonic contamination, voltage dips, rapid voltage variations and reactive current.
The result is polluted sine wave form. Your existing installation - including transformers, cabling and protective devices - was often not originally designed for this complexity. This creates Power Quality problems that initially remain invisible. Without intervention, these effects accumulate ("the bucket fills up"), until the limit of your installation is reached and operational reliability is compromised.
The impact of the energy transition on Power Quality manifests itself in various technical phenomena. For the technical manager and installation manager, it is crucial to distinguish them. Only with the right diagnosis can we eliminate the cause.
Modern inverters switch at very high frequencies to be more efficient and compact. These so-called supraharmonics behave differently from classical harmonics.
Consequence: They can go right through capacitors and resonate in your installation. This often leads to failures in control electronics, PLCs, touchscreens and smart meters, resulting in inexplicable process stops.

Many companies fear grid congestion on the public grid, but forget about congestion within their own gates. Electrification increases energy demand, while solar feed-in creates peaks.
Consequence: Your internal transformers and main distributors become overloaded, even when average consumption seems to be within standards. By reducing reactive current and harmonics, you can often free up capacity ("Capacity Release") and postpone costly reinforcements.
Switching on and off large power, such as a fleet of electric vehicles starting charging at the same time or a heat pump switching on, causes dips and spikes.
Impact: Sensitive equipment in hospitals or data centres needs a stable voltage. A brief dip can be enough to cause systems to fall into failure, resulting in data loss or product failure.
Power quality problems often lurk long before they escalate. However, when the limit is reached, the consequences are immediately felt in your operations. For sectors with critical processes, such as industry, healthcare and data centres, these risks are unacceptable.
At HyTEPS, we do not believe in trial and error or blindly fitting a standard filter. The complexity of modern installations requires a scientific, data-driven approach. We take over responsibility from problem definition to solution.
Our engineers start with a thorough analysis of your installation. We perform a Power Quality measurement and install advanced measuring equipment to record the quality of voltage and current over a representative period. We look beyond standard standards; we look for the specific interactions between your sources (PV, Grid) and your loads (EV, machines).
Data is just the beginning. With the collected measurement data, we build a digital model of your electrical installation in our advanced simulation software. In this 'Digital Twin' environment, we test the effects of possible solutions.
Based on the simulation, we implement the technically and economically best solution. This can range from rearranging transformers (taps) to installing Active Harmonic Filters (AHF) or capacitor banks. We do not just supply hardware; we deliver a working system that secures your operational reliability and makes your installation compliant with the standards again.

As an installation manager, you have to deal with strict standards. The energy transition makes compliance more complex.
HyTEPS not only helps you technically, but also ensures that you demonstrably comply with these regulations. We provide reports that you can submit to insurers and grid operators.
Solar photovoltaic (PV) systems generate direct current, which is converted to alternating current by an inverter (inverter). This switching process always causes some degree of harmonic contamination. In addition, when there is a lot of solar irradiation and low offtake, the voltage in the system can get so high that inverters fail to protect the grid. This leads to yield losses.
Electric vehicles charging at high powers. The simultaneous initiation of multiple charging sessions creates peaks in the load (inrush currents). Moreover, chargers contain rectifiers that generate harmonics and supraharmonics. Without filtering, this can lead to overheating of transformers, neutral conductors and faults in other connected equipment.
Grid congestion, simply put, is congestion on the power grid. At peak times, the demand for power (or the supply in case of feed-in) is greater than the cables and transformers can handle. As a result, grid operators refuse new connections or reinforcements to companies.
Yes, in part. Grid congestion often takes place on the grid operator's network, but you can optimise your internal capacity. By reducing reactive current and harmonic contamination, you reduce the useless current flowing through your cables and transformers. This frees up space ("Free capacity") for new equipment, such as additional charging stations or heat pumps, without you needing a heavier (and often unavailable) grid connection straight away.
LED lighting uses non-linear power supplies (drivers) that introduce harmonic currents. In large healthcare facilities with thousands of luminaires, this contamination adds up, leading to overheating of neutral conductors and transformers, and unexplained failure of other sensitive electronics.
The cos phi concerns only the phase shift of the ground wave, while the power factor includes the influence of harmonics. We analyse both values to determine the overall efficiency of your installation.
This is not always necessary. Heat pumps are large consumers that often use variable speed drives. This puts extra strain on the transformer, both thermally and through harmonics. By first carrying out a Power Quality measurement and simulation, HyTEPS can determine whether you can keep the current transformer by applying active filtering, for example. This saves considerable investment costs and lead time.
Supraharmonics are disturbances in the frequency range between 2 kHz and 150 kHz. They are mainly caused by modern inverters in solar panels and EV chargers. These high frequencies are notorious for passing right through capacitors. They cause communication failures in smart meters, building management systems and PLCs. They are often the cause of 'ghost faults' that cannot be explained by standard measurement equipment.
There are several standards such as EN 50160 (for voltage at the transfer point) and the IEC 61000 series (for EMC and Power Quality within installations). HyTEPS tests your installation against these standards through advanced measurements. We deliver a clear report that indicates in understandable language where you are at risk and how to become compliant again.
This is a common issue in sustainability. The filters in variable speed drives and inverters 'leak' a small current to earth as part of their operation. If you have many appliances on one group, these leakage currents add up and the earth leakage circuit breaker will trip without an actual fault. Harmonic currents can also cause this behaviour. An analysis of the leakage currents provides the answer here.
Investing in Power Quality is not a cost, but a business case. It delivers immediate returns: you avoid costly downtime, extend the life of your equipment and make maximum use of your existing connection capacity. It gives you the certainty that your sustainable ambitions will not come at the expense of operational reliability. It creates peace of mind in the organisation.
Don't let invisible pollution block your sustainable ambitions. Choose security and continuity. HyTEPS is ready to future-proof your installation.
