Voltage Variations: impact and solutions

Voltage variations, defined as increases or decreases in the voltage amplitude compared to the nominal value, represent a frequent and problematic phenomenon. These variations can be caused by fluctuations in input power, variations in loads (such as starting the motors or maneuvers in the system) and faults on the system. These variations constitute one of the main Power Quality problems, causing damage to electrical and electronic equipment and causing significant disruptions.

Among the most recurring problems, due to voltage variations, there are shutdowns and anomalies in processes and machinery, interventions of power electronics protections, premature aging of system components and malfunctions of electronic devices. Voltage variations can manifest themselves in the form of overvoltages and undervoltages, with variable durations over time based on the conditions of the system and electrical distribution.

How to eliminate voltage variations?

To effectively deal with voltage variations, IREM offers a complete range of voltage stabilizers designed to guarantee a perfectly stabilized electrical voltage: the MINISTAB and STEROSTAB stabilizers.

IREM voltage stabilizers are recognized for their great reliability, particularly appreciated in installations in locations that are difficult to reach and subject to critical environmental conditions. They are capable of compensating for large variations in mains voltage, an essential feature for systems far from distribution substations or located in developing countries. They offer high stabilized voltage accuracy, ideal for applications such as calibration and test benches, electric ovens and professional lighting fixtures.

Furthermore, IREM voltage stabilizers are particularly suitable for high-power users or with high inrush absorption, such as motors, air conditioners, compressors and pumps. Thanks to their design, they require simple and limited maintenance, a significant advantage in areas where it is difficult to find qualified personnel.

MINISTAB voltage stabilizers are electronically controlled electromechanical equipment, ideal for single-phase and three-phase users of small and medium power. Their operation is based on a control circuit that constantly monitors the line voltage and compares it with the pre-set value, guaranteeing high regulation speed values and stabilization precision.

The STEROSTAB voltage stabilizers, on the other hand, are designed for single-phase and three-phase users of high and very high power. Their architecture allows reaching high values of regulation speed and precision in stabilization, making these devices insensitive to the power factor of the load and capable of avoiding the introduction of harmonic distortions.
