Improving Process Control Immunity to Supply Voltage Sags in Petroleum and Chemical Industries
(Energy Systems Laboratory (http://esl.tamu.edu), 1998-04)
In the modern industrial facility, many electrical and electronic control devices are routinely integrated into automated processes to increase both energy efficiency and productivity. In many cases these controls turn out ...
Voltage Sag-Related Upsets of Industrial Process Controls in Petroleum and Chemical Industries
(Energy Systems Laboratory (http://esl.tamu.edu), 1998-04)
In the modern industrial facility, many electrical and electronic control devices are routinely integrated into automated processes, increasing the potential for electrical compatibility problems. Hardwired motor control ...
Studies in Power Quality Success
(Energy Systems Laboratory (http://esl.tamu.edu), 2000-04)
The California Energy Commission is actively supporting research and development to improve power quality. Poor power quality can result in productivity losses and compromise safety. Dealing with power quality problems ...
The Constant Voltage Transformer (CVT) for Mitigating Effects of Voltage Sags on Industrial Equipment
(Energy Systems Laboratory (http://esl.tamu.edu), 2000-04)
Electric quality problems associated with
power interactions between distribution and industrial process control systems can be prevented. Surveys of large users that buy power at the transmission and distribution voltages ...
Improving Cooling System Immunity Supply Voltage Sags in Petroleum and Chemical Industries
(Energy Systems Laboratory (http://esl.tamu.edu), 2000-04)
Electrical service faults and voltage discontinuities are of growing concern in process industries where individual sensitive equipment or controls can disrupt the entire plant. In fact, just a minor variation in power for ...
