Takeaways

• 😀 The first equipment mentioned is the transformer substation, which is part of the electricity distribution system, used to transform electrical power.
• 😀 The second equipment is electrical wiring, which includes conductors and components like transformers, isolators, and reclosers.
• 😀 A generator set (genset) is connected to a turbine, which powers a generator to produce electricity that is then transmitted to a substation for further distribution.
• 😀 Transformers are used to change the electrical power, maintaining the same frequency but adjusting voltage levels for proper distribution.
• 😀 A circuit breaker is a protection device that safeguards electrical systems from voltage spikes and faults by disconnecting the power when necessary.
• 😀 Potential transformers step down high voltage for measuring purposes, ensuring safety and accuracy in electrical monitoring.
• 😀 Electrical conductors distribute electricity from the transformer to consumers, with some systems operating underground for safety and aesthetics.
• 😀 Disconnecting switches are used to disconnect circuits when no current is flowing, often used during maintenance or to ensure system stability.
• 😀 Lightning arresters protect electrical systems from lightning strikes by providing a low-resistance path for the surge, preventing damage to the equipment.
• 😀 Capacitors store electrical energy temporarily and act as conductors in AC systems, while providing insulation or resistance in DC systems.

Q & A

What is the role of a 'Gardu Induk' in the electrical system?

A 'Gardu Induk' or substation is a subsystem of the electrical power distribution system, functioning to transform electrical power and distribute it to different parts of the network.

What are the primary types of electrical poles mentioned in the transcript?

The three primary types of electrical poles mentioned are wood, steel, and concrete poles, each used for different purposes depending on the environment, such as overhead or underground systems.

What is the function of a generator set in an electrical power system?

A generator set (genset) is connected to a turbine. The rotation of the turbine generates electricity by turning the rotor of the generator, which produces voltage transmitted to substations for further distribution.

How does a transformer work in an electrical power system?

A transformer works by transforming electrical power, changing its voltage level while keeping the frequency constant, which is essential for efficient power transmission and distribution.

What is the purpose of a circuit breaker in an electrical system?

A circuit breaker is a protective device that provides safety by interrupting the electrical circuit in case of overvoltage or short-circuit conditions, preventing damage to electrical equipment.

What is a potential transformer and why is it important?

A potential transformer steps down high voltage in electrical systems to lower levels for use in instruments such as meters, gauges, and relays, ensuring safety and accurate measurements.

What is the purpose of conductors in an electrical system?

Conductors are used to carry electric current from the transformer to consumers, facilitating the transmission of electrical power throughout the distribution system.

What is the role of a disconnecting switch in an electrical system?

A disconnecting switch is used to isolate sections of an electrical system for maintenance or repair, ensuring safety and the continued operation of the power system without disruptions.

What does a lightning arrester do in an electrical system?

A lightning arrester protects electrical systems from lightning strikes by providing a low-resistance path for the lightning current, preventing damage to electrical equipment.

How does a fuse contribute to an electrical system’s safety?

A fuse acts as a safety device in electrical systems. It melts and breaks the circuit when excessive current flows through, protecting the system from potential damage caused by overcurrent or short circuits.
