The AVCRTS is an Industrial Uninterruptible Power Supply (UPS). It prevents downtime by correcting short-term outages, deep voltage sags and overvoltage.
With companies reporting a near doubling of short-term power outages since 2017, the AVCRTS has become increasingly important to maintain production during short-term outages.
The AVCRTS is specifically designed to handle the unique conditions found in industrial environments, including:
Unlike commercial UPS systems, the AVCRTS is built to handle these conditions and provide a reliable source of power to protect against unexpected power disturbances.
The AVCRTS is connected between the supply and the load and works by monitoring the voltage and ensuring that it stays within user-defined limits.
If the voltage level drops below its threshold, the AVCRTS disconnects the load from the utility and connects to the battery source within ¼ cycle. Once the voltage is restored from the utility or supplied from a standby generator, the inverter synchronizes with the supply, reconnects to the load and disconnects the battery.
The AVCRTS handles high inrush current, high harmonic distortion, and loads with regenerative back feed. These conditions stem from the dynamic loads created by equipment in industrial facilities.
Typical conditions that reduce the reliability of a UPS connected to a dynamic load:
Poweroutages, also called a blackout, are the loss of the electrical power on onephase, two or three phases.
IEEE 1159 defines an interruption as follows:
The main reason for power outages is the weather, such as:
Other factors that contribute to power outages include wildlife and tree branches striking power cables. These interruptions occur due to recloser operations from the utility. As a result, a short power outage can last anywhere from a few milliseconds to a few seconds.
Momentary power interruptions occur due to recloser operations from the utility. As a result, a short power outage an last anywhere from a few milliseocnds to a few seconds. Common causes of recloser operations include faults occuring during lighting storms, trees and animals coming into contact with power lines.
