The challenge of the modern medical installation: Why Power Quality is now more critical than ever

Over the past decade, the technical infrastructure of hospitals has changed dramatically. Whereas an installation used to feed mainly linear loads, the modern healthcare network consists of a complex mix of non-linear loads. Think of the huge power electronics in MRI scanners and CT systems, but also of the tens of thousands of LED drivers and frequency-controlled ventilation systems that are crucial for the indoor climate.

At HyTEPS, we understand that 'fixing' is not enough. We focus on improving the overall condition of your plant. A proactive approach starts with understanding how all these systems interact. Without a clear diagnosis, you keep fighting symptoms instead of solving the cause. This not only compromises operational reliability, but also leads to unnecessarily high maintenance costs and a shorter lifespan of your valuable assets.

Not only is this modern equipment a source of harmonic distortion, it is also extremely sensitive to the same contamination. When the Power Quality within your installation deteriorates, symptoms arise that are often misdiagnosed:

  • Mysterious tripping of protection devices without identifiable overload.
  • Unexplained resets of sensitive medical equipment during critical treatments.
  • Premature failure of LED lighting and computer power supplies.

Our integrated approach for a healthy healthcare installation

Engineers view measurement

1. Diagnosis & Analysis

A healthy electrical installation in a hospital does not start with a product, but with a flawless diagnosis. At HyTEPS, we use a scientific approach to reveal the invisible processes within your installation. We look beyond standard values and focus on the interaction between complex medical systems and the energy supply.

Many healthcare facilities experience symptoms such as overheated cables, premature wear of capacitor banks or unexplained communication errors in the building management system. These problems can often be traced back to harmonic contamination caused by non-linear loads such as medical equipment power supplies and large-scale LED lighting. Without a proactive approach and the right measurement data, you keep fighting symptoms, while the real cause continues to undermine operational reliability .

2. Analyse and Simulate

Our engineers use advanced simulations and modelling software to calculate scenarios (such as Load Flow and harmonic analyses). What happens to the voltage quality if an additional MRI scanner is installed? How does the installation react when switching to emergency power? By answering these questions in advance, we prevent incidents instead of correcting them afterwards. We provide you with the technical reliability you need to blindly trust your infrastructure.

Soon the problem was addressed and now the clock has been operating without any problems for years.

Frequently asked questions about Power Quality in industry

Answer:

In a hospital, dependence on electronics is absolute. Medical equipment such as ventilation and monitoring systems have very close tolerances for voltage variations. Whereas a computer reboot in an office is merely a nuisance, equipment failure in an OR can directly compromise patient safety.

Answer:

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.

Answer:

Inverters of PV installations can cause high-frequency contamination and voltage fluctuations. This can interfere with the sensitive signals of medical measuring equipment, causing noise or error messages in diagnostic systems.

Answer:

Yes, particularly due to reactive power and harmonic contamination. This causes additional losses in transformers and cables (heat). Optimising quality improves efficiency and reduces operating costs.

Answer:

Active harmonic filters act as a power 'cleaning system'. They monitor pollution in real time and inject a countercurrent that cancels the harmonics. This protects the plant and ensures a clean voltage for medical equipment.

Answer:

We recommend a proactive approach in which critical points are continuously monitored. In case of major changes to the installation, such as the construction of a new wing or the installation of a new MRI, a comprehensive diagnosis and baseline measurement is essential.

Answer:

Our engineers work strictly according to the relevant standards. We translate complex data into reports that help you demonstrate that your installation is safe and reliable, in accordance with legal frameworks.

Answer:

Aggregates have a higher impedance than the grid. Harmonic currents can disrupt the voltage regulation of an aggregate, jeopardising the stability of the emergency power supply during a grid failure.

Answer:

Harmonics cause additional losses and heat in a UPS's filters and capacitors. This can lead to premature aging of the batteries and, in extreme cases, shutdown of the UPS because the electronics can no longer handle the polluted sine wave form correctly.
