I applied via Campus Placement and was interviewed in Jan 2024. There were 2 interview rounds.
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.
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

Yes, SCADA stands for Supervisory Control and Data Acquisition. It is a system used for monitoring and controlling industrial processes.
SCADA systems are used in various industries such as power plants, water treatment facilities, and manufacturing plants.
They allow operators to remotely monitor and control processes in real-time.
SCADA systems typically consist of sensors, controllers, and a human-machine interface (HM...
Types of losses in power distribution include resistance losses, core losses, and dielectric losses.
Resistance losses occur due to the resistance of the conductors, leading to heat dissipation.
Core losses occur in transformers due to hysteresis and eddy current losses.
Dielectric losses occur in insulating materials due to polarization and leakage currents.
Power distribution system is a network of electrical components used to deliver electricity from the generation source to the end users.
Power generation at a central location
Transmission of electricity through high voltage lines
Distribution through substations and transformers
Delivery to end users via distribution lines
Utilization by consumers for various applications
Types of transformers include power transformers, distribution transformers, autotransformers, isolation transformers, and instrument transformers.
Power transformers are used in high voltage transmission systems to step up or step down voltage levels.
Distribution transformers are used to supply power to residential and commercial areas.
Autotransformers have a single winding and are used for voltage regulation.
Isolation...
