Hello Friends. In last post we shared a lot of mcq on high voltage
engg. Now we are going to share interview question on high voltage
engg. In this post, breakdown in gases, liquids and solids is mostly
discussed. Lets start and enjoy interview question of high voltage
engineering.
Q.1 Mention the types of insulating materials which is used in high
voltage engineering?
Ans - Insulating materials are four types.
A. Solids
B. Liquids
C. Gases
D. Vacuun
Q.2 What are the salient properties of usual metals ?
Ans: These are:
A. Specific resistivity in ohm meter.
B. Temperature resistance coefficient.
C. Specific Gravity.
D. Tensile strength when used in overhead line.
Q.3 What are the usual materials for conductors used in high voltage
equipment and transmission lines?
Ans- Conductors are mostly fabricated from metals. Depending on the
equipment the following metals are found in high voltage work, gold,
silver, copper, aluminium, tin, lead, iron, nickel, chromium
