The term POWER QUALITY is commonly understood as the ability of electrical energy to properly supply user equipment. It is a critical factor for the continuity, efficiency, and safety of production processes and the most sensitive professional applications.
POWER QUALITY is influenced by voltage and current conditions, and is often compromised by overvoltages, undervoltages, voltage dips, frequency fluctuations, or harmonic disturbances. These anomalies are caused by network faults, load variations, atmospheric events, and even by the loads themselves.
What are the consequences of bad Power Quality?
An insufficient level of POWER QUALITY can lead to:
- Damage to equipment: malfunctions in motors, errors in industrial processes, shutdowns in POWER LIGHTING systems, and damage to electronic devices;
- Increased energy costs: energy losses and inefficiencies in electrical systems;
- Service interruptions: disruptions and productivity losses.
Electrical disturbances affecting Power Quality
Distribution lines, subject to continuous load variations, cannot ensure stable voltage. Although energy providers allow a tolerance of ±10% from the nominal value, in practice, there are often slow variations (from overloads and undersized lines), overvoltages (in the absence of industrial absorption), and rapid changes (from the insertion of heavy loads).
In particular, voltage imbalance in three-phase networks can cause serious problems: a 2.3% imbalance on a 400 V motor leads to a current imbalance of 18%, with a temperature increase of about 30 °C.
What is the most reliable solution to manage voltage fluctuations?
IREM Ministab and Sterostab voltage stabilisers offer a concrete and proven solution to these issues. Designed to ensure perfectly stabilised voltage, they allow:
- Prevention of faults caused by network fluctuations;
- Increased system reliability;
- Improved overall level of POWER QUALITY;
- Reduction of costs related to disruptions and plant downtimes.
Why are voltage stabilisers an investment in Power Quality?
Ensuring high POWER QUALITY means protecting systems, devices, and processes from faults, unexpected downtimes, and efficiency losses. In this light, IREM Ministab and Sterostab voltage stabilisers are a strategic solution: not only do they correct grid fluctuations, but they also directly improve the quality of power supply in a stable and continuous manner.
The use of these devices makes it possible to prevent significant economic losses, often associated with unplanned interruptions or premature equipment degradation. In many industrial contexts, avoiding even a single critical fault or just a few minutes of downtime can be enough to justify the entire investment.
