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... Learn More
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... Learn More
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... Learn More
Power Transformer Maintenance Author: Velimir Lackovic Transformer preventative maintenance involves routine inspection, adjustment, testing, minor fixes, and special handling instructions. The trouble-free and reliable operation of transformers over their usable life depends on proper installation, operation, and maintenance. This course provides an overview of the typical procedures that are performed as part of transformer preventive... Learn More
Power Cable Testing Author: Velimir Lackovic This course covers power cable testing procedures including visual inspection, cable failures and their analysis, insulation and conductor defects, field testing of medium voltage cables and different cable testing methods. It covers issues related to different failure types such as mechanical failures, overheating, chemical actions etc. and ways to... Learn More
