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... 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... 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... Learn More
