A substation is a facility that transforms high voltage electricity to lower voltage for distribution to consumers.

• Substations play a crucial role in the power grid by facilitating the transmission and distribution of electricity.

• They receive electricity from power plants or transmission lines and transform it to a lower voltage suitable for distribution.

• Substations contain various equipment such as transformers, circu...read more

Circuit breakers are devices that protect electrical circuits from damage caused by overload or short circuit.

• Types of circuit breakers include air circuit breakers, oil circuit breakers, vacuum circuit breakers, and SF6 circuit breakers.

• Air circuit breakers are commonly used in low voltage applications, while oil circuit breakers are used in high voltage applications.

• Vacuum circuit breakers are used in medium voltage ...read more

A transistor is a semiconductor device used to amplify or switch electronic signals and power.

• Transistors are used in electronic devices such as radios, televisions, and computers.

• They can be used as amplifiers to increase the strength of a signal.

• They can also be used as switches to turn a signal on or off.

• Transistors come in different types such as bipolar junction transistors (BJTs) and field-effect transistors (FET

The interviewer is asking about common problems with motor meggers.

• Common problems with motor meggers include incorrect readings due to dirty or damaged insulation, faulty connections, or incorrect test settings.

• Ensure proper cleaning and maintenance of the megger to avoid inaccurate readings.

• Check for loose or damaged connections before testing to ensure accurate results.

• Verify that the test settings on the megger are...read more

Resistance is the opposition to the flow of electric current in a circuit.

• Resistance is measured in ohms (Ω).

• It is caused by the collisions of electrons with atoms in a material.

• Higher resistance leads to lower current flow in a circuit.

• Resistance can be affected by factors like material, length, and temperature.

• Example: A light bulb has resistance that converts electrical energy into light and heat.

Inductance is the property of an electrical circuit that opposes changes in current flow.

• Inductance is measured in Henry (H)

• It is caused by the magnetic field generated when current flows through a conductor

• Inductors are components that are designed to have a specific inductance value

• Inductance is used in filters, transformers, and motors

Capacitance is the ability of a system to store an electric charge.

• Capacitance is measured in Farads (F).

• It is the ratio of the electric charge stored on a conductor to the potential difference across it.

• Capacitors are electronic components that are designed to store and release electrical energy.

• Capacitance is used in various applications such as filtering, energy storage, and timing circuits.

Electricity can be produced through various methods such as burning fossil fuels, harnessing renewable energy sources like wind and solar, or using nuclear reactions.

• Burning fossil fuels like coal, oil, and natural gas in power plants to generate steam that drives turbines connected to generators.

• Harnessing renewable energy sources like wind turbines to convert kinetic energy into electricity.

• Using solar panels to conv...read more
