Roulunds Braking Electrical Maintenance Engineer Interview Questions, Process, and Tips

A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Consists of two coils of wire (primary and secondary) wrapped around a core

• Primary coil receives electrical energy and creates a magnetic field

• Magnetic field induces a voltage in the secondary coil, transferring energy to the secondary circuit

• Used to step up or step down voltage levels in power dist...read more

PLC programming stands for Programmable Logic Controller programming, which involves writing code to control industrial automation processes.

• PLC programming involves writing code to control the operation of machinery and equipment in industrial settings.

• It uses ladder logic, function block diagrams, or structured text to create programs that dictate the behavior of the PLC.

• Programs are written to monitor inputs from se...read more

VCB stands for Vacuum Circuit Breaker, a type of circuit breaker that uses vacuum as the arc quenching medium for interruption of electrical current.

• VCB is used for switching and protection of electrical equipment in power systems.

• It is more reliable and requires less maintenance compared to other types of circuit breakers.

• VCBs are commonly used in medium voltage applications.

• Safety measures when working with VCB inclu...read more

ACB stands for Air Circuit Breaker, which is a type of circuit breaker used for protecting electrical circuits and equipment. Safety measures include proper installation, maintenance, and operation of ACBs.

• ACB is a type of circuit breaker that operates in the air instead of oil or gas.

• ACBs are used to protect electrical circuits and equipment from overloads, short circuits, and other electrical faults.

• Safety measures f...read more

DG stands for Diesel Generator and safety refers to the measures taken to ensure the safe operation and maintenance of the generator.

• DG is a backup power source that runs on diesel fuel in case of power outages.

• Safety measures for DG include regular maintenance checks, proper ventilation, and fire prevention protocols.

• Safety precautions also involve training personnel on how to operate the DG safely and what to do in c...read more
