Protecting Process Quality with ABB's Active Voltage Conditioner

AGC Display Glass

ABB’s Active Voltage Conditioner system, the PCS100 AVC-40, improves quality and productivity at AGC Display Glass, a major supplier of glass substrates for display technologies. The technology guards sensitive industrial production processes from the disturbances and harm caused by voltage fluctuations in the utility power supply.

The most common cause of plant malfunctions in advanced manufacturing facilities with high levels of meticulousness automation are voltage sags and surges. Without power protection, such substantial interruptions can occur between 12 and 18 times a year. Eradicating lost production due to down time and associated quality issues can transform the competitiveness of a facility.

“Businesses choose ABB’s Active Voltage Conditioners to protect processes where the loss of voltage for even a few milliseconds results in the failure of the machinery and damage to its yield,” said Shen Xiang, Sales Specialist for ABB’s Power Protection business in China. “The PCS100 AVC-40 is the most efficient solution available –– and it provides higher levels of overload capability to handle conditions that defeat competitor systems.”

Active Voltage Conditioner

The PCS100 AVC-40 uses ABB’s established Active Voltage Conditioner system to correct voltage issues promptly, maximizing productivity. ABB has installed two systems at the company’s Shenzhen facility to safeguard the manufacturing process control system, quality inspection equipment and automation for glass cleaning and material handling. The systems adjust voltage variations in less than five milliseconds, guaranteeing these operations continue to run smoothly. A redundant internal bypass system also ensures continuity of supply from the utility.

“To succeed in this competitive and technologically complex industry, reliable power protection is paramount,” explains Li Jin, Electrical Manager at AGC Display Glass. “With more than 4,000 hours of production accrued so far since the AVC’s installation, ABB’s solution has completely eliminated the shallow voltage sags that would normally affect our highly sensitive glass inspection equipment. ABB’s commitment to quality, innovation and the level of service on hand made the upgrade straightforward.”

Advantages of ABB Solutions

ABB’s PCS100 AVC-40 allows factories to streamline their resources. The unit uses utility power, eliminating the requirement for costly on-site generators to stabilize power supplies. And, because it draws the energy for voltage corrections from the utility supply, batteries are not necessary, further lowering maintenance costs.

ABB’s compressed design makes it simple to install in confined spaces such as machine rooms, freeing up floor space. Its minimal heat emission means energy efficiency surpasses 98% and cooling needs are lowered.

AGC Display Glass of Shenzhen City, China is one of the world’s principal manufacturers of glass substrates. Their technologies are employed in a wide range of thin film transistor (TFT) displays, liquid crystal displays (LCDs) and organic LEDs. The company’s advanced manufacturing methods are critical to its global competitiveness.
