America’s Greatest Projects and Their Engineers III Author: Dominic Perrotta American engineers achieved phenomenal success by creating the Trans-Alaska Pipeline, a project that many thought was almost impossible for a variety of reasons. Not only was the climate against them, but they also had to deal with the environment, the ecology, mountain ranges, and precipitous…
Voltage Transformers Author: Velimir Lackovic Voltage transformers are constructed in two configurations based on their intended purpose: magnetic voltage transformers (VT) and capacitive voltage transformers (CVT). The magnetic voltage transformers are more economical for voltages up to 145 kV, and the capacitive voltage transformers are more economical for voltages higher than 145 kV. A CVT…
Power Transformer Testing Author: Velimir Lackovic Transformers may be tested using either AC or DC voltage. AC voltage is preferable to DC voltage for transformer testing because it simulates the internal stress that the transformers face during operating conditions. This course is suitable for engineers interested in learning about commonly used transformer testing procedures. It…
