What are voltage spikes?
Voltage spikes are very short-duration pulse disturbances that can reach voltage values of thousands of volts. They are generated by various sources, including switching on high-voltage lines, the insertion of power factor correction capacitors, lightning, and the disconnection of loads with high reactive power. Even low-power loads, such as photocopiers and air conditioners, can contribute to this phenomenon when they are connected to the same power line by generating transient spikes.
What problems do they cause?
These events can be particularly dangerous for the most susceptible users, as they can cause malfunctions and failures in electronic devices. Due to their very short duration, voltage spikes are not detectable with a normal voltmeter, making their management and prevention difficult. However, they represent one of the main causes of failures and disruptions in electrical networks, with significant impacts on operating costs and service reliability.
What solutions does IREM offer to protect the electricity grid?
Statistically, phenomena that reduce the quality of energy supplied by the electricity grid account for over 95% of electrical anomalies, causing failures and disruptions for all connected users.
Adopting adequate solutions for protection from voltage spikes is essential to guarantee the safety and reliability of electricity networks: IREM is committed to providing advanced technologies to improve energy quality and protect users from electrical disturbances.
IREM Ministatic and Steroguard, line conditioners designed to provide a high level of protection to electrical users, are particularly effective against voltage surges, high frequency conducted disturbances and voltage spikes.

IREM integrated power supplies, designed to solve power quality problems in transmission stations in the telecommunications sector, are equipped with safety, protection, sectioning, connection and signaling systems. Furthermore, they guarantee continuous and reliable operation even in the presence of electrical disturbances.

The IREM IT series isolation transformer offers excellent galvanic separation and high noise attenuation. Featuring recessed concentric windings, low output impedance and insensitivity to power factor, it represents an effective solution against voltage peaks, helping to protect the integrity of electrical utilities.
