I applied via Referral and was interviewed in Oct 2024. There was 1 interview round.
Transformers work on the principle of electromagnetic induction to transfer electrical energy between two or more circuits.
Transformers have two coils of wire, known as primary and secondary coils, which are magnetically coupled.
When an alternating current flows through the primary coil, it creates a changing magnetic field which induces a voltage in the secondary coil.
The ratio of the number of turns in the primary an...
To replace a blown 22 kv line fuse, safety measures include de-energizing the line, using proper PPE, and following proper procedures.
De-energize the line before attempting to replace the fuse
Use insulated tools to avoid electrical shock
Wear appropriate PPE such as rubber gloves, safety glasses, and flame-resistant clothing
Follow proper lockout/tagout procedures to ensure the line remains de-energized during the replac...

The current in a transformer is made by inducing voltage across the primary coil.
The primary coil of a transformer is connected to an alternating current (AC) source.
The alternating current in the primary coil creates a changing magnetic field.
This changing magnetic field induces a voltage across the secondary coil.
The induced voltage in the secondary coil causes a current to flow through it.
The current in the secondar...
DC shunt motors are a type of direct current motor that have a parallel field winding and a series armature winding.
DC shunt motors have a parallel field winding and a series armature winding.
They are commonly used in applications that require constant speed and moderate starting torque.
The speed of a DC shunt motor can be controlled by varying the field current or the armature voltage.
DC shunt motors are widely used i...
A DC shunt motor is a type of direct current motor that has a shunt field winding connected in parallel with the armature winding.
The field winding and armature winding are connected in parallel
The shunt motor has a relatively constant speed-torque characteristic
The speed of the motor can be controlled by varying the field current
The motor provides good starting torque
The shunt motor is commonly used in applications wh...
