Ashok Leyland Interview Questions, Process, and Tips for Experienced

HIRA stands for Hazard Identification and Risk Assessment.

• HIRA is a process used to identify potential hazards and assess the risks associated with them.

• It involves identifying hazards, evaluating the likelihood and severity of potential consequences, and determining appropriate control measures.

• HIRA is commonly used in industries such as construction, manufacturing, and oil and gas.

• Examples of hazards that may be iden...read more

EMS stands for Energy Management System.

• EMS is a computer-based system that helps manage energy consumption in buildings and facilities.

• It monitors and controls energy usage, identifies areas of inefficiency, and suggests ways to improve energy efficiency.

• EMS can be used in a variety of settings, including commercial buildings, hospitals, and industrial facilities.

• Examples of EMS include building automation systems, li...read more

A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

• Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.

• They consist of two coils of wire, called the primary and secondary coils, wrapped around a magnetic core.

• When an AC voltage is applied to the primary coil, it creates a magnetic field th...read more

APFC panel is used to improve power factor and reduce energy consumption.

• APFC panel helps in maintaining a high power factor which reduces energy consumption and saves money.

• It also helps in reducing voltage drops and improves the efficiency of electrical equipment.

• APFC panel is especially useful in industries where there are a lot of inductive loads such as motors and transformers.

• It monitors the power factor and auto...read more

Megger is used to measure insulation resistance in electrical systems.

• To ensure the safety of electrical systems and prevent electrical hazards.

• To detect any insulation breakdown or leakage in the system.

• To identify any potential faults or defects in the system.

• To comply with industry standards and regulations.

• Examples: testing cables, transformers, motors, generators, etc.

A permit system is a set of procedures and documents required to ensure safety and compliance with regulations before starting a job.

• Permit systems are used to control hazardous work activities.

• They involve obtaining permits and following specific procedures before starting work.

• Examples include hot work permits, confined space permits, and excavation permits.

• Permit systems help prevent accidents and ensure compliance ...read more

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.

• Compressors are used in various industries such as refrigeration, air conditioning, and gas processing.

• They come in different types such as reciprocating, rotary, and centrifugal compressors.

• Reciprocating compressors use pistons to compress gas, while rotary compressors use rotating impellers.

• Centrifugal compressors use a ro...read more

Relays are used to control high voltage or current circuits using low voltage signals.

• Relays provide electrical isolation between the control circuit and the load circuit.

• They can switch high voltage or current circuits using low voltage signals.

• Relays are used in applications such as motor control, lighting control, and power distribution.

• They can also be used for safety functions such as emergency shutdowns.

• Relays ar...read more

PM stands for Preventive Maintenance and RM stands for Reactive Maintenance.

• PM is a scheduled maintenance activity that aims to prevent equipment failure.

• RM is a maintenance activity that is performed after equipment failure.

• PM is proactive while RM is reactive.

• PM involves regular inspections, cleaning, and replacement of parts.

• RM involves troubleshooting, repairing, and replacing faulty parts.

• Examples of PM include ch...read more
