Transformers

Question 1

transforms electric energy from one circuit to another circuit at the same frequency.

Answer 1

Transformers

Question 2

Types of Transformers according to construction

Answer 2

Core and shell Type Transformers

Question 3

the winding are placed outside the core

Answer 3

Core Type Transformers

Question 4

the windings are placed inside the core such that the magnetic circuit almost completely surrounds the winding.

Answer 4

Shell Type Transformers

Question 5

Is the ratio of the amount of magnetic flux linking a secondary coil compared to the flux generated by the primary coil.

Answer 5

Coefficient of coupling

Question 6

A step down transformer converts high voltage from the primary side to low voltage on the secondary coil resulting in a decrease in the output voltage.

Answer 6

STEP DOWN TRANSFORMERS

Question 7

These types of transformers work almost the same as step down transformers.

Answer 7

STEP UP TRANSFORMER

Question 8

• A single-phase transformer is a type of power transformer that uses single-phase alternating current, which means it relies on a voltage cycle that operates in an integrated time phase.

Answer 8

SINGLE PHASE TRANSFORMER

Question 9

These transformers are used to convert the voltage of electronic systems with three phase.

Answer 9

THREE PHASE TRANSFORMERS

Question 10

• They are usually large in size and do not have any rotating or moving parts.

Answer 10

POWER TRANSFORMER

Question 11

The distribution transformer provides the last or final voltage change in the power distribution syster.

Answer 11

DISTRIBUTION TRANSFORMER

Question 12

These transformers are used to measure electrical
and power factor.
quantities like

Answer 12

MEASUREMENT OR INSTRUMENT
TRANSFORMER

Question 13

• Current transformers are commonly used to reduce or multiply alternating current (AC).

Answer 13

CURRENT TRANSFORMER

Question 14

This type of transformer is used to transfer electrical power from an alternating current while isolating the powered device for safety reasons.

Answer 14

ISOLATION TRANSFORMER

Question 15

Potential transformers or voltage transformers are commonly used to reduce voltage levels.

Answer 15

POTENTIAL TRANSFORMER

Question 16

In this transformer, both the primary and secondary windings are set on a nonmagnetic stripe. It has flux linkage in both the windings through the air.

Answer 16

AIR CORE TRANSFORMER
