Tap Changing Transformer: Working principle, Nameplate readings
The purpose of tap changer in a transformer is to keep the output voltage within an acceptable range when system conditions vary. In practice, the voltage on the power network keeps
Tap changer
No-load tap changer (NLTC), also known as Off-circuit tap changer (OCTC) or De-energized tap changer (DETC), is a tap changer utilized in situations in which a transformer''s turn ratio does not require frequent changing and it is permissible to de-energize the transformer system. This type of transformer is frequently employed in low power- low voltage transformers in which the tap point often may take the form of a transformer connection terminal, requiring the input line to be disconnected by
