Voltage sags are temporary drops of voltage below the nominal value, typically between 10% and 90%, lasting from 10 milliseconds to one minute.
Micro interruptions are even shorter events, with complete voltage drops lasting from 10 to 500 milliseconds.
Although brief, these disturbances can severely disrupt automated production systems and lead to significant operational inefficiencies.
Voltage sags between 10% and 90% of the nominal value, lasting between 10 ms and 1 minute (typically less than 1 s and greater than 40%), are defined as ‘sags’ (IEC EN 50160).
Micro interruptions, on the other hand, involve total voltage drops for short periods (10-500 ms, often between 200-500 ms).
Voltage sags often occur during the start-up of heavy electrical equipment, network switching operations or external faults.
Micro interruptions arise from transient disturbances or switching on shared lines.
Even when energy supply meets normative standards, it may not suit the real-time requirements of modern, sensitive industrial equipment.
Over 60% of the costs related to poor power quality are due to voltage sags and micro interruptions.
These effects can reach up to 4% of a company’s annual turnover.
The consequences range from halted production lines and system resets to long-term wear on electrical infrastructure and increased maintenance costs.
In response to these problems, OrteaNext offers two distinct and complementary technologies.
Oxygen is designed to counteract longer-lasting voltage sags/dips. Thanks to an ultra-fast response time of less than 3 milliseconds, it ensures voltage continuity without the use of batteries, guaranteeing high performance with low operating costs.
Oxygen Zero, on the other hand, is designed to intervene in micro-interruptions. Its architecture with supercapacitors and IGBT technology makes it ideal for highly sensitive industrial environments, protecting the most delicate devices from very short but frequent disturbances.
Oxygen is the ideal solution for voltage SAGs.
Oxygen Zero is the ideal solution for micro interruptions.
With more than 50 years of expertise, OrteaNext delivers certified Made in Italy solutions for power quality and energy efficiency. Each system is tailored to the client’s installation, ensuring maximum protection and energy savings. Improving power quality means safeguarding productivity, extending the lifespan of your equipment, and making your energy investments more valuable.
What’s the difference between a voltage sag and a micro interruption?
A voltage sag is a partial drop in voltage, while a micro interruption causes a total voltage drop for a very short period.
Why are UPS not ideal in these scenarios?
UPS systems are bulky, require regular battery maintenance, and have lower energy efficiency. OrteaNext’s solutions are more compact and targeted.
How do I know if my plant is affected by these disturbances?
OrteaNext provides on-site audits and energy quality analysis, delivering precise reports and tailored proposals.
