Answer / rajkumar

for making -more time
for breaking-less time why?

when moving contact starts leave from fixed contact
during breaking at that time arc will develope this arc
follow to the moving contact upto rest position of the
contact but arc quench media didnot allow this process
incase breaking cpacity is more means arc presence in
between contact is long time so it is damage the breaker

during making moving contact touch or very near to the
fixed contact on that short time only arc produce

Answer / sudheer

because of the inductance associated with the circuit, it
takes time to establish magnetic fields around all the
wires and whatnot. This requires extra current at startup.

Answer / kumar

when we make the circuit ON at that time a suddern inrush
current the steep traveling current wave) flow to the
network or to the device due to the presence of circuit
parameters like as inductance, capacitance. that time the
current value is more than the breaking current.Thats why
the making capacity is more than the breaking capacity.

Answer / guest

if any fault is create in systeam at the time breaker must
be open in within seconds ( it is 2 to 3 sec. )otherwise
very denger fault is create and we loss a very costly
equipment.

we done magnetic balance test for 33KV /440V transformer in our company , but the ratio out is confusing us Voltage applied in RY = 440 , at RB = 320 and YB = 60 RY 440 = ( RB + YB ) 380 only Please let me know what type of problem is it.

ASTM D 3455 - Standard Test Methods for Compatibility of Construction Material with Electrical Insulating Oil of Petroleum Origin has been used for Testing Transformer Oils with a product placed in it. Aged Control Oil has a Power Factor of 0.032% at 100°C. Aged Oil with a Test component has a Power Factor of 0.093% at 100°. Is this increase acceptable? If not why? How much increase is acceptable?
