Answer / sangram
Air Blast CB. High restriking voltage appears across the
contacts because of current chopping. If these voltages are
not allowed to discharge, they may cause break down of
insulation of the circuit breaker or the neighboring
equipment.

Answer / raul
ABCB.......during current chopping, capacitive current breaking.......high transient voltages r produced......resistance switching avoids dis by connecting a shunt resistance across d cb contacts.......

Answer / nikhil sharma
oil filled circuit breakers use resistor switching to
balance the voltage distribution amongst the contacts of
circuit breaker and to reduce the transient overvoltages
produced during arc inhibition process...

Answer / srinivas.k.p
b)Air blast c.b in that we reduce the re-striking voltage b\w the moving contact and fixed contact by using the resistance and allows the current though reverse leakage current will be avoided only we resistance used in air blast c.b other than we can't use in oil r gas..

Answer / alpesh
can anybody tell me what is the use of that resistor switch???

Why material of brush is carbon in motors why not other material.
Basic laws governing motor and generator
We have two Al.busbars each of size 125mm*10 mm connected in parallel.To increase the current rating ,can we connect third busbar of size 100mm*10mm in parallel to existing two busbars?In my opinion ,if we connect busbars of different sizes in parallel,then the busbar of lowest size will take much current.So this type of paralleling should be avoided .Am I correct?
What mean 150 amp hour write on battery.
We need to current density & short circuit calculation at 65kA for aluminium & copper busbar.
can we use 3 phase UPS for Motors and Other Machines
