Satguru Electrical Work Interview Questions, Process, and Tips

Resistive, inductive, and capacitive loads are types of loads in electrical circuits that affect the flow of current and voltage.

• Resistive load: Converts electrical energy into heat, such as incandescent light bulbs.

• Inductive load: Creates magnetic fields when current flows through, like motors and transformers.

• Capacitive load: Stores electrical energy temporarily, seen in capacitors.

Load lamp is used to indicate the presence of load in a circuit.

• Load lamp lights up when there is a load connected to the circuit.

• It helps in visually confirming the operation of the circuit.

• It can be used to troubleshoot circuit connectivity issues.

• Common examples include indicator lights on appliances or machinery.

Endurance testing of switches and sockets involves repeatedly turning them on and off to simulate real-world usage.

• Endurance testing involves repeatedly operating the switch or socket to ensure it can withstand a certain number of cycles without failure.

• The test may involve applying a specified load or current to the switch/socket during operation.

• Examples of endurance testing methods include mechanical cycling tests a...read more

Temperature rise in a 10 amp switch can be checked by measuring the temperature increase during testing.

• Use a thermometer to measure the initial temperature of the switch

• Apply a 10 amp load to the switch for a specific testing time

• Measure the temperature of the switch after the testing time

• Calculate the temperature rise by subtracting the initial temperature from the final temperature

• Ensure the temperature rise is with

High voltage tester is used to test electrical equipment for insulation breakdown. The process involves connecting the tester to the equipment and applying high voltage to check for any insulation faults.

• Ensure the high voltage tester is properly calibrated before use

• Connect the tester to the equipment being tested

• Apply high voltage to the equipment and monitor for any insulation breakdown

• Record the test results and en...read more
