Investigation the effect of secondary burden of current transformer (CT)
(Universiti Malaysia Perlis (UniMAP), 2011-05)
Current Transformers (CT’s) are instrument transformers that are used to supply a
reduced value of current to meters, protective relays, and other instruments. CT’s provide
isolation from the high voltage primary, permit ...
Study of single phase transformer inrush current
(Universiti Malaysia Perlis (UniMAP), 2011-05)
When a transformer is initially connected to a source of AC voltage, there may be a substantial surge of current through the primary winding called inrush current. This analogous to the inrush current exhibited by an ...
Power transformer magnetization under different frequency supply
(Universiti Malaysia Perlis (UniMAP), 2011-05)
Transformer is a vital link in a power system which has made possible the power
generated at low voltage to be stepped up to extra high voltages for transmission over
long distances and then transformed to low voltages ...
