Dr. Reddy's Interview Questions, Process, and Tips for Experienced

An isolator is a device used to separate a section of a system or equipment from the rest for safety or maintenance purposes.

• Isolators are commonly used in electrical systems to disconnect a circuit from its power source.

• They can also be used in pharmaceutical manufacturing to separate a process area from the surrounding environment.

• Isolators are designed to prevent contamination or exposure to hazardous materials.

• Some...read more

RCCB stands for Residual Current Circuit Breaker, a device designed to quickly disconnect power in the event of a leakage current.

• RCCB is a safety device used to protect against electric shock and fire hazards.

• It monitors the imbalance of current between the live and neutral conductors.

• If a leakage current is detected, the RCCB trips and disconnects the circuit.

• RCCBs are commonly used in residential, commercial, and in...read more

RCBO stands for Residual Current Circuit Breaker with Overcurrent Protection.

• RCBO is a type of circuit breaker that combines the functions of a residual current device (RCD) and a miniature circuit breaker (MCB).

• It provides protection against both earth faults (residual current) and overcurrents.

• RCBOs are commonly used in electrical installations to protect against electric shock and fire hazards.

• Example: A 20A RCBO wo...read more

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

• Consists of two coils of wire, known as primary and secondary windings

• Primary winding receives electrical energy and creates a magnetic field

• Magnetic field induces a voltage in the secondary winding, transferring energy to the load

• Used in power distribution, voltage regulation, and isola

LT HT stands for Low Tension High Tension, referring to different voltage levels in electrical systems.

• LT refers to low voltage systems typically up to 1000V, while HT refers to high voltage systems typically above 1000V.

• LT systems are commonly used in residential and commercial buildings for lighting and small appliances.

• HT systems are used in industrial settings, power distribution networks, and large machinery.

• LT HT...read more
