Anglo-Eastern Ship Management Electro Technical Officer Interview Questions and Answers

The three lamp motor method is a technique used to determine the direction of rotation of a three-phase motor.

• The method involves connecting three lamps in a star or delta configuration to the motor windings.

• When the motor is started, the lamps will light up in a specific sequence depending on the direction of rotation.

• By observing the sequence of lamp lighting, the direction of rotation of the motor can be determined.

Tree lamp method is a technique used to test the insulation resistance of electrical equipment.

• Tree lamp method involves connecting a high voltage source to the equipment under test and measuring the insulation resistance.

• The test is performed by applying a voltage between the conductors and the earthed parts of the equipment.

• The insulation resistance is calculated using Ohm's Law: R = V/I, where R is the resistance, V...read more

Oil mist detectors work by sensing the presence of oil mist in the air to prevent potential hazards in machinery.

• Oil mist detectors use optical sensors to detect the presence of oil mist particles in the air.

• They are commonly used in industries like marine, power generation, and manufacturing to prevent machinery breakdowns or fires.

• When oil mist is detected, the system triggers an alarm or shuts down the machinery to ...read more

Mgps colorinaition type refers to the color coding used in Multi-Grounded Power Systems.

• Mgps colorinaition type is used in Multi-Grounded Power Systems to differentiate between different grounding points.

• Color coding helps in easily identifying the grounding points and ensures proper grounding connections.

• Examples of color coding in Mgps colorinaition type include green for equipment grounding, yellow for isolated grou

The question seems to be asking about the concept of alternating current in electrical engineering.

• The question may be referring to the concept of alternating current (AC) in electrical engineering.

• AC is a type of electrical current where the flow of electric charge periodically reverses direction.

• AC is commonly used in homes and businesses to power electrical devices.

• Examples of devices that use AC include refrigerato
