The magnetising current of a transformer is usually small because it has small air gap.
Description : The secondary of a current transformer is always short-circuited under operating conditions because it?
Answer : The secondary of a current transformer is always short-circuited under operating conditions because it avoids core saturation and high voltage induction.
Answer : No-load current of a transformer has small magnitude and low power factor.
Answer : The transformer ratings are usually expressed in terms of kVA.
Answer : Material used for construction of transformer core is usually silicon steel.
Answer : The thickness of laminations used in a transformer is usually 0.4 mm to 0.5 mm.
