TP Central Odisha Distribution Interview Questions, Process, and Tips

Q1. Types of distribution networks
Ans. 
Distribution networks can be categorized into radial, loop, and network types.
• Radial distribution network: Power flows in one direction from the source to the load.

• Loop distribution network: Power flows in multiple directions forming loops for redundancy.

• Network distribution network: Power flows through interconnected paths for reliability and flexibility.

Q2. Types of relays
Ans. 
Relays are electrically operated switches used to control high power circuits with low power signals.
• Electromechanical relays: use electromagnets to mechanically operate the switch (e.g. SPST, DPDT)

• Solid-state relays: use semiconductor devices to perform switching action (e.g. SSR)

• Time delay relays: provide a delay before switching (e.g. ON delay, OFF delay)

• Overload protection relays: protect circuits from excessive cu

Q1. What is transformer
Ans. 
A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.
• Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.

• They consist of two coils of wire, known as the primary and secondary coils, which are wrapped around a magnetic core.

• When an AC voltage is applied to the primary coil, it creates a magne...read more

Q2. Transformer working principle
Ans. 
Transformers work on the principle of electromagnetic induction to transfer electrical energy from one circuit to another.
• Transformers have two coils of wire, a primary coil and a secondary coil, wrapped around a magnetic core.

• When an alternating current flows through the primary coil, it creates a magnetic field that induces a voltage in the secondary coil.

• The voltage induced in the secondary coil is proportional to t...read more

Q4. What is eddy current loss
Ans. 
Eddy current loss is the energy lost due to the resistance of a material to the flow of eddy currents induced by a changing magnetic field.
• Eddy current loss occurs in conductive materials when they are exposed to a changing magnetic field.

• This loss is due to the resistance of the material to the flow of eddy currents.

• Eddy current loss can be reduced by using laminated cores in transformers and motors.

• Examples of eddy c...read more

Q5. What is core loss
Ans. 
Core loss is the energy lost in the magnetic core of a transformer or inductor due to hysteresis and eddy currents.
• Core loss is also known as iron loss.

• It is caused by the magnetic field in the core constantly changing direction, which causes the core to heat up and energy to be lost.

• Hysteresis loss is caused by the magnetic domains in the core constantly changing direction, which causes friction and energy loss.

• Eddy c...read more

Q1. What is the formula of transformer short circuit test ?
Ans. 
The formula for transformer short circuit test is Vsc = (Isc * Zsc)
• The short circuit test is performed to determine the impedance and losses of a transformer.

• The formula for short circuit test is Vsc = (Isc * Zsc), where Vsc is the short circuit voltage, Isc is the short circuit current, and Zsc is the impedance of the transformer.

• The short circuit test is conducted by applying a reduced voltage to the primary winding ...read more
