Why a standard inspection often misses the cause

Inspections such as SCIOS Scope 8 (basic safety) and Scope 10 (fire risk) are important, but they mainly test against inspection criteria. Our measurements look at the physics ín the installation: what do voltage and current in the conductors do under different operating and fault conditions, and how do parts of the grid affect each other. We map not only abnormalities, but also cause-effects, trends over time and the impact on components and processes. This also makes 'invisible' risks measurable, such as accelerated ageing and lifetime shortening of cables, connections and equipment due to long-term electrical stress.

Modern installations are complex. The increase in power electronics (LED lighting, variable speed drives, EV chargers and solar panels) creates contamination on the grid. This leads to problems that are not visible with a standard multimeter. Think of harmonic contamination that melts cables while the current seems nominal, or high-frequency EMC faults that disrupt control systems.

Engineer measuring

The symptoms of an unhealthy installation:

  • Printed circuit boards of machines that inexplicably fail frequently.
  • Flickering lights or buzzing transformers.
  • PLCs or IT systems that spontaneously reset.
  • Safeguards that trigger without obvious overload.

A complete spectrum of electrical engineering measurements

Each complaint requires a specific instrument and expertise. We divide our measurement services into four main pillars to analyse every aspect of your installation.

Engineers view measurement

Power Quality

The basis of a healthy installation. We measure voltage and current quality to identify phenomena such as harmonic contamination, imbalance, and voltage dips . Essential for operational reliability.

Energy & Efficiency (Power Flow)

Understanding your consumption profile. We analyse reactive current, peak loads and energy flows. This is the basis for penetration, resolving grid operator penalty clauses and energy savings.

Measurement and diagnostics
Oscilloscope measurement

EMC Research (Electromagnetic Compatibility)

For problems occurring in the higher frequencies (kHz to MHz). Interference between devices often causes fuzzy malfunctions in control technology and data traffic. We detect the source of interference, including harmonic contamination of PV inverters, charging stations and battery systems. But also interference that may be related to grounding problems.

EMF Measurements (Electromagnetic Fields & Radiation)

Human and environmental safety. We measure the magnetic field strength around transformers and distribution equipment to assess compliance with health guidelines and health and safety legislation. We also measure to trace possible failures due to radiation.

Power Quality Measurement & Grid Analysis: in depth

A Power Quality measurement is the starting point for solving most electrical problems. To get to the core, we connect our advanced analysers directly to critical points in your distribution.

What we measure and analyse: Our engineers analyse hundreds of parameters. The most common culprits we identify are:

Continuous Waveform Recording Unique to HyTEPS' approach is the use of equipment with 'continuous waveform recording'. Many standard meters only record averages per second or minute. This often 'averages out' the cause of an ultra-short fault. Our measuring equipment logs (if necessary) every sine waveform over the entire measuring period. This allows us to look back to the millisecond what happened just before, during and after an incident. This is crucial for 'forensic investigations' after outages.

EMC Research: Beyond standard frequency

EMC spectogram

Besides 'classic' Power Quality problems, we see an explosion in high-frequency faults (EMC). Modern installations are full of switched-mode power supplies. A device with a switched power supply could cause a fault or accelerated wear on another device.

EMC: The silent disruptor Do you suffer from measurement errors in sensors, dropped data connections or earthing problems? Chances are this is an EMC (Electromagnetic Compatibility) problem. This takes place in frequencies well above 50Hz (up to 150kHz or higher). Standard power quality meters don't see this. HyTEPS has specialised oscilloscopes and spectrum analysers to visualise this 'noise' and locate the source.

Energy & Capacity Management

Measuring is also knowing how much room you have left. Many companies want to electrify (heat pumps, EV chargers), but do not know whether their current transformer or main connection can handle it. Through a comprehensive load analysis, we map your current load profile. We advise you on residual capacity and how to get more power from your existing connection by 'Peak Shaving' or reducing reactive current.

Our approach: from measurement to solution

For HyTEPS, measurement is only the starting point. We do not provide raw data, but a diagnosis and a solution. Our engineers go through a set protocol to ensure quality.

  1. Intake & Preparation: We discuss your complaints, installation schedule and processes. Based on this, we determine the measurement strategy and equipment required.
  2. Installation Measuring equipment: our certified engineers install the equipment on site. This is usually done under voltage (if safely possible), so that your production process does not have to be interrupted. Depending on the problem, we measure for a day, a week or longer.
  3. Analysis by Experts: This is where we make a difference. You don't get a printout from software. Our engineers manually analyse terabytes of data, make connections and filter out noise from relevant events.
  4. Reporting & Advice: You will receive a clear report in understandable language. We describe the findings, conclusions and - most importantly - concrete advice for improvement.
  5. Aftercare & Implementation: If required, we assist in the engineering and implementation of the solutions, such as the installation of active filters or capacitor banks.
Approach from measurement to solution

High-quality equipment and certified engineers

A surgeon is only as good as his knowledge and his instruments. At HyTEPS, we continuously invest in both. Our team consists of highly qualified electrical engineers (HBO/WO) who receive continuous internal and external training in the field of Power Quality and EMC.

We work brand-independently, but use only the top-of-the-range from the measurement world. Our arsenal includes:

Power Quality Analyzers
  • Power Quality Analyzers: for long-term logging in accordance with EN 50160
  • Blackbox: For continuous waveform recording (never miss an event)
  • Oscilloscopes: For high-frequency EMC analyses
  • Spectrum analyser: for radiated EMC measurements up to the GHz spectrum
  • Various dedicated probes and sensors: For current measurements from milliamps to thousands of amperes.

Because we have dozens of meters at our disposal, we can measure (synchronised) simultaneously at several points in your installation in the event of complex faults. This allows us to see exactly how a failure propagates through your installation.

Frequently asked questions about measurements and analyses

Answer:

For a complete analysis in accordance with the EN 50160 standard, we recommend a minimum of one week (7 days). This ensures that we map all business processes, including weekends and shifts. For specific failures, a day's measurement may sometimes suffice.

Answer:

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.

Answer:

In most cases, they don't. Our engineers are trained to work safely in the vicinity of voltage-carrying parts and place the measurement probes while your installation remains in operation. Your production is not affected.

Answer:

Costs depend on the complexity and size of your installation. However, the cost of one hour of production downtime is often many times higher than the investment in a survey. Speak to an engineer for a tailor-made estimate.

Answer:

This is possible, but we often advise against it for complex problems. Meter placement (correct phase sequence, type of current probes) is crucial for reliable data. Moreover, our engineers on site often see things in the installation that a meter does not.

Answer:

Yes, we carry out EMF (Electromagnetic Fields) measurements. We often do this in office buildings, hospitals or near heavy transformers to test whether the field strength remains within safe values for human exposure.

Answer:

Yes. If our analysis shows that harmonic filters or capacitor banks are needed, we can dimension, supply and commission them (together with you). You can buy this hardware from us and install it yourself, or let us supervise this.

Answer:

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.

Answer:

Absolutely. We are not an inspection agency that just diagnoses a problem. We recommend concrete solutions, such as harmonic filters or capacitor banks, and can also supply and commission them for you.

Answer:

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.

Answer:

Yes, this is a common problem. Often the cause lies in voltage dips or harmonic contamination overloading the inverter's input stage. We can demonstrate this through measurements.

Answer:

Yes, absolutely. Although our headquarters and heart are in the Netherlands, our services reach worldwide. Our engineers regularly fly out to offshore locations, international industrial areas and data centres across borders to solve complex issues. Electricity behaves according to the same laws of nature all over the world, so our knowledge is universally applicable.

Don't keep guessing about the cause

Every day that an outage persists is a risk to your business continuity. Let our experts look into your installation. We provide clarity, hard facts and a working solution.
