Deltron Plant and Machinery Incharge Interview Questions and Answers

A capacitor is an electronic component that stores and releases electrical energy.

• A capacitor consists of two conductive plates separated by an insulating material called a dielectric.

• When a voltage is applied across the plates, one plate accumulates positive charge while the other accumulates negative charge.

• Capacitors are commonly used in electronic circuits to store energy, filter out noise, and stabilize voltage le...read more

Star delta is a method of starting three-phase motors with reduced voltage.

• It involves connecting the motor windings in a star configuration during starting and then switching to a delta configuration once the motor is up to speed.

• This reduces the starting current and torque, which can be useful for large motors or when the power supply is limited.

• For example, a 30 kW motor might draw 60 amps at full voltage, but only ...read more
