HV Testing for On Load Brush Change in Engineering

Play an AI-generated podcast conversation about this lesson

What is the primary purpose of the HV DC test set used in this procedure?

To measure the insulation resistance of the sample under test
To measure the voltage applied to the sample under test
To measure the dielectric strength of the PPE
To measure the current flowing through the sample under test (correct)

What is the main precaution to be taken when conducting this high voltage proving test?

Ensure the area is cordoned off with security tape
Ensure overload protection of the test set (correct)
Ensure the voltage is raised and lowered gradually
Ensure the sample under test is placed on a clean surface

What is the purpose of measuring the insulation resistance (IR) of the sample before and after the high voltage test?

To ensure the sample meets the required insulation resistance
To ensure the test set is functioning correctly
To ensure the sample is not damaged during the test (correct)
To ensure the earthing system is working properly
