Demonstrating that your electrical installation complies with set standards is not an administrative formality, but a technical necessity. At a time when installations are becoming increasingly complex due to power electronics and renewable generation, 'compliance' is the only way to ensure operational reliability and limit liability risks.
A Power Quality report provides you with black-and-white evidence about the health of your voltage and current. It translates invisible phenomena into clear conclusions against standards such as EN50160, the Electricity Grid Code or the IEC 61000 series. Whether it is a delivery test, a periodic inspection or a dispute with the grid operator: without valid reporting, you are technically and legally weak. HyTEPS helps you interpret data and turn it into action.
Short on time? Here are the key points you need to know:
The aim: To demonstrate that voltage and power quality remain within legal or contractual limits.
The need: compliance is often required for warranty claims, insurance policies and to avoid fines from the grid operator (e.g. for harmonic emission).
Standards: The most commonly used frameworks are EN50160 (public grid) and IEC 61000-2-4 (industrial environment).
The action: To measure is to know, but to analyse is to understand. A report without expert interpretation is worthless. Provide continuous monitoring or specialised measurements at the Point of Common Coupling (PCC).
Reporting and compliance are essential topics for professionals responsible for the continuity and safety of critical infrastructure.
Compliance in the context of electrical energy means that the characteristics of voltage and current meet predetermined requirements. This is a two-way street:
Grid Compliance deals specifically with a grid operator's requirements at the point of connection (Point of Common Coupling). Increasingly, grid operators require proof prior to a connection that your installation will not violate the grid code. This often requires sophisticated simulations and power quality studies even before the first cable is laid.
Nuance: Complying with the standard does not always mean you have no problems. EN50160 is a statistical standard for the public grid. For a sensitive data centre or hospital, these requirements are often too broad. Customised limit setting is therefore often needed for internal operational reliability.
Ignoring standards and lacking insightful reporting carries several risks. It is not just about avoiding a fine, but about the continuity of your operations.
Not every standard is suitable for every situation. Misapplication of standards is a common mistake in reporting.
Often, you only notice non-compliance when it is too late. Yet there are early indicators:
Real-life example: A hospital experienced unexplained failures in laboratory equipment. The equipment supplier pointed to the power supply, the technical service to the device. A one-week measurement showed that the installation complied with EN50160, but that specific high-frequency harmonics were disturbing the sensitive equipment. By reporting against the more stringent equipment specifications, the cause could be identified and resolved with active filtering.
To ensure and prove compliance, you go through a structured process. A snapshot is rarely enough for this.
It is not always necessary to engage an external party directly. However, in the following specific situations, the expertise of a Power Quality specialist is necessary to manage risks and costs:

Symptoms are often subtle until things go wrong. Look out for unexplained machine failures, flickering lights, cables getting hot or transformers buzzing. Also, if electronics (PLCs, drivers) fail earlier than the service life indicates, chances are that the power quality is insufficient. A Power Quality measurement provides the answer.
This is possible, provided you have a high-quality Power Quality Analyzer (according to IEC 61000-4-30 Class A) and the knowledge to interpret the data. Collecting data is easy; analysing the correlation between events, harmonics and your specific business processes requires specialist engineering knowledge. We are happy to support you in the analysis.
Not by definition. NEN-EN 50160 describes the minimum requirements for voltage at the grid operator's transfer point. However, modern equipment can be more sensitive and malfunction even if the voltage is within this standard. We therefore look beyond the standard: we look at the compatibility between your power supply and your connected load.
Peace of mind, certainty and insight. You get a clear diagnosis of the 'health' of your electrical installation. We pinpoint the cause of faults, enabling you to avoid unplanned downtime and reduce fire risks or unnecessary energy losses. You receive a concrete advisory report with practical points for improvement.
No, that is a misconception. A filter is a powerful tool, but not a panacea. Sometimes the solution lies in changing transformer settings, redistributing loads or adjusting cabling. HyTEPS always recommends a thorough analysis and simulation before we recommend hardware, to avoid unnecessary investments.
Yes, significantly. Solar panel inverters and LED lighting drivers are non-linear loads that cause harmonics and sometimes supraharmonics. This can lead to interference with other equipment or overloading of the neutral conductor. When renovating or preserving, a Power Quality check is essential to ensure operational reliability.
We call this phenomenon 'nuisance tripping'. Often the cause is not the total amount of current, but the distortion of the current (harmonics) or short peak currents that your measuring equipment misses. This contamination can extra heat up thermal protections or confuse electronic protections, causing them to switch off wrongly. A specialised measurement can find out exactly why a protection reacts.
For a reliable picture, we usually measure at least one to two weeks. This is necessary to capture a full duty cycle, including weekends and peak loads. For specific acute failures, we can also take short-term measurements or deploy 'continuous waveform recording' to capture transients.
Your installer is an expert in installation and maintenance (the 'general practitioner'). HyTEPS is the specialist (the 'Power Quality Doctor'). We have advanced measuring equipment, simulation software and in-depth knowledge of theoretical electrical engineering and regulations. We often work together with installers to solve complex puzzles that fall outside standard knowledge.
After the measurement, you receive a report with conclusions in understandable language as well as technical details. If necessary, we simulate the possible solutions in our software. So you know exactly what the effect of a measure will be in advance. We then supervise the implementation and verify the result with a follow-up measurement.
Doubting whether your installation complies with the Grid Code or experiencing unexplained failures? Don't wait for things to go wrong. Speak to an engineer from HyTEPS for an analysis or a no-obligation review of your current metering data. We will help you go from data to solution.
