Safety and continuity are fundamental to any business. HyTEPS provides assurance with in-depth analyses, security studies and specialist service. We make invisible risks transparent and protect your employees and business processes.
You know that electricity leaves no room for errors or assumptions. Yet the most dangerous situations often arise out of sight, in the heart of the installation. An electrical installation that complies with all the rules on paper can still be vulnerable in practice. Factors such as ageing, frequent extensions and increasing grid pollution play a crucial role here.
Modern industry is changing rapidly. The integration of power electronics, LED lighting, variable speed drives and PV systems introduces new variables into your energy network. These components can affect the operation of standard safeguards, creating risks that standard controls might miss. Consider the impact of an unintended shutdown in a critical process, or the serious consequences of an arc incident on your technical staff.
As an organisation, you bear the burden of these risks. You are not looking for temporary solutions, but fundamental security. HyTEPS helps you bear that responsibility. We look beyond the 'tick' on the checklist. By analysing, modelling and periodically maintaining your installation, we create an environment where safety and operational reliability go hand in hand.
When it comes to safety, people often immediately think of physical shielding, earthing and insulation. However, an underestimated component in this safety issue is the quality of the electrical energy itself: Power Quality. When voltage and current deviate from the ideal sinusoidal waveform, physical reactions occur within your components that directly jeopardise safety.

One of the most common problems is harmonic distortion. This phenomenon causes additional energy losses that manifest as heat. Due to the ‘skin effect’ and eddy currents, cables, transformers and motors can become severely overheated, even if the measured current (RMS) appears to fall within the rated values. The neutral conductor poses a specific risk. In three-phase systems, so-called ‘third harmonics’ can accumulate in the neutral conductor. As the neutral conductor is often not protected against overcurrent, it can become red-hot without being noticed, resulting in melting insulation and fire. Our engineers identify these harmonics and advise on filtering to eliminate this fire risk at source.
In addition to thermal risks, power quality affects your safety components. Voltage dips, surges or high-frequency disturbances can cause safety switches and circuit breakers to trip unnecessarily (‘nuisance tripping’). This may seem like nothing more than an annoying interruption, but it compromises the reliability of your system. Worse still, it can mean that a circuit breaker fails to respond when it really needs to. An installation that behaves unpredictably is, by definition, unsafe for users and maintenance technicians.
To measure is to know, but to calculate is to predict. To stay ahead of calamities, it is necessary to simulate the behaviour of your installation under fault conditions. HyTEPS carries out detailed studies on your installation model. This way, we ensure that your safety devices do what they are supposed to do: protect.

Are you certain that your switchgear can withstand the enormous forces of a short circuit? If the short-circuit current at a particular point in the installation exceeds the breaking capacity (kA) of your circuit breakers, they may explode in the event of a fault rather than switching off safely. This poses an immediate risk to life. Our engineers calculate the maximum and minimum short-circuit currents at every point in your infrastructure. This enables us to verify whether your components can withstand the thermal and dynamic effects of a fault current. This calculation forms the basis of a safe design and is increasingly becoming a strict requirement imposed by insurers.
In the event of an electrical fault, it is crucial that the impact is minimised. You want only the circuit breaker directly above the fault to trip, and not the main distribution board that supplies the entire factory. We refer to this principle as selectivity. In practice, we regularly see that main and sub-circuit breakers are not properly coordinated, meaning that a minor fault in a terminal group leads to a total blackout. Through a comprehensive selectivity analysis, we optimise the settings of your protective devices. We analyse the tripping characteristics (amperometric, chronometric and logical) and ensure correct grading. In this way, we guarantee maximum operational reliability: a fault is isolated locally, whilst the rest of your process continues uninterrupted.


An arc flash is one of the most devastating incidents that can occur in an electrical installation. The explosive energy released during an arc flash – in the form of heat, pressure, light and sound – is life-threatening to anyone in the vicinity. HyTEPS carries out specialised arc flash calculations in accordance with international standards such as IEEE 1584 and NFPA 70E. We determine the potential arc flash energy (incident energy) at each workplace. Based on this, we advise on the necessary Personal Protective Equipment (PPE) and safe working distances. We also look beyond this: by making smart adjustments to safety settings, we can often significantly reduce the arc flash energy. This allows you to lower the risk from ‘life-threatening’ to a manageable level.
An electrical installation is not a static entity. Components age, connections can loosen due to vibrations and settings can expire over the years. Therefore, a one-off good design and adjustment is not enough. You must be able to demonstrate that you are in control of safety at all times. HyTEPS supports you in this with high-quality service on your installation.

Our engineers periodically check the vital parts of your installation. In doing so, we look beyond standard standards and focus on the actual condition of your electrical infrastructure. Possible risks due to wear and tear or contamination are immediately identified.
It is essential to be sure that your protection relays and circuit breakers are still responding exactly as calculated. With advanced test equipment, we simulate fault currents to validate the response time and accuracy of your protection devices.


Using thermal imaging cameras, we scan your distributors for hotspots. This brings bad contact crossings or overloads into focus without having to shut down the installation.
Together with you, we draw up a maintenance plan that matches the criticality of your installation. This shifts you from reactive fire-fighting to proactive management and prevents overdue maintenance from becoming a safety risk.

Yes, we read the logs and do snapshots to see if the filter is still functioning correctly and meeting its targets. However, for a comprehensive analysis of the entire installation (e.g. in case of vague complaints elsewhere in the premises), we recommend a specific Power Quality Analysis.
For contract customers with critical processes, we can make specific SLA agreements on response times and availability outside office hours. Standard failures are handled with high priority within office hours.
We understand that downtime costs money. For urgent matters, we try to respond as quickly as possible, often within 24 to 48 hours. For less urgent analyses, we plan in consultation.
We recommend a regular checkup to identify degradation in time. Our service department has the right equipment to measure condition precisely.
Electronic components and insulation materials wear faster due to heat and voltage spikes. By stabilising the voltage and keeping it 'clean', you avoid these stressors, making equipment last years longer.
Our focus is on Power Quality and the quality of voltage and current (NEN-EN 50160). However, Power Quality is an essential part of a safe installation. We can supplement your inspection report with in-depth measurements that go beyond the standard NEN 3140 scope.
NEN 3140 is a safety inspection focusing on touch hazard and fire safety at a basic level. It does not look at voltage quality or the influence of equipment on each other. A 'safe' installation can still be very unreliable due to Power Quality problems.
