PASAV stands for Pressure Actuated Safety and Automatic Valve. It is used to control the flow of fluids in a system based on pressure levels.

• PASAV is a type of valve used in mechanical systems.

• It automatically opens or closes based on the pressure levels in the system.

• PASAV helps in maintaining safe pressure levels in the system to prevent damage or accidents.

• Example: PASAVs are commonly used in hydraulic systems to re

To work in open spanner, place the spanner on the nut or bolt and turn it in the desired direction.

• Select the correct size of open spanner for the nut or bolt

• Place the open end of the spanner on the nut or bolt

• Turn the spanner in the desired direction to loosen or tighten the nut or bolt

• Ensure the spanner is securely placed on the nut or bolt to avoid slipping

Types of welding include MIG, TIG, stick, and flux-cored welding.

• MIG welding uses a wire electrode and shielding gas to create a strong bond.

• TIG welding uses a tungsten electrode and inert gas for precise and clean welds.

• Stick welding uses a consumable electrode coated in flux to create a strong bond.

• Flux-cored welding uses a tubular wire filled with flux for outdoor and windy conditions.

The pressure in a VCB in vacuum interrupter remains around 10^-6 to 10^-7 torr.

• The pressure in a VCB in vacuum interrupter is typically maintained at around 10^-6 to 10^-7 torr.

• This low pressure helps in preventing arcing and ensures efficient interruption of the circuit.

• Maintaining a vacuum in the interrupter chamber helps in improving the dielectric strength of the medium.

• Examples of VCBs with vacuum interrupters inc
