TP Central Odisha Distribution Graduate Engineer Trainee (Get) Interview Questions and Answers

The first 5 things I will notice during an inspection of a distribution network

• Overall layout and organization of the distribution center

• Condition of equipment and machinery used in the distribution process

• Inventory levels and storage capacity

• Safety measures and protocols in place

• Efficiency of the distribution process and any bottlenecks

Different types of losses in a LT Network include copper losses, iron losses, and stray losses.

• Copper losses: Occur due to resistance in the conductors, leading to heat dissipation.

• Iron losses: Result from hysteresis and eddy current losses in the transformer core.

• Stray losses: Arise from leakage flux and other inefficiencies in the network.

• Examples: A transformer experiencing iron losses will heat up due to hyste...read more

Steady state stability refers to the ability of a power system to maintain a stable operating condition under normal operating conditions.

• Steady state stability is important for ensuring the reliability of the power system.

• It is affected by factors such as load demand, generator output, and transmission line capacity.

• If the power system is not in steady state stability, it can lead to voltage instability, frequenc...read more

One and a half breaker scheme is a protection scheme used in power systems to provide selective tripping of faulty sections.

• It involves using one full circuit breaker and one half circuit breaker to protect a section of the power system.

• The full circuit breaker is used to protect the main section while the half circuit breaker is used to protect the adjacent section.

• If a fault occurs in the adjacent section, the h...read more

Protection measures are necessary to ensure safety and reliability of distribution systems.

• Protection devices such as fuses, circuit breakers, and relays are used to detect and isolate faults.

• Grounding systems are used to protect against electrical shock and lightning strikes.

• Backup power sources such as generators and batteries are used to ensure continuity of service.

• Regular maintenance and testing of protection...read more
