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:
