Voltage Transformers

COURSE NO: E03-042
PDH CREDIT: 3
Voltage Transformers
Course Highlights

This online engineering PDH course presents information on voltage transformers, including basic engineering laws, measuring error, voltage factor, burden and accuracy class, non-linear burdens, different voltage transformer winding connections, Ferro resonance and specific applications for protection schemes.

 

There are two types of voltage transformers, magnetic voltage transformers (VT) and capacitive voltage transformers (CVT). The magnetic voltage transformers are most economical for voltages up to about 145 kV and the capacitive voltage transformers for voltages higher than 145 kV. A CVT can also be used together with the Power Line Carrier (PLC) devices that are used for communication over the high voltage transmission circuits.

 

This 3 PDH online course is suitable for engineers and technicians with a desire to understand the fundamental theory and operating principles of voltage transformers. Upon successful completion engineers will be able to address different terms related to voltage transformers, understand their operational principles and various applications.
