Rupturing capacity or breaking capacity expresses the current that a circuit breaker is capable of breaking at a given recovery voltage under certain set conditions of operation. It is expressed in MVA The set conditions are power factor,recovery voltage and rate of rise of restriking voltage. When the current broken is symmetrical it is called symmetrical breaking capacity. When the current broken is asymmetrical it is called asymmetrical breaking capacity. It is common to designate circuit breaker capacity based on asymmetrical breaking capacity. Breaking capacity of a circuit breaker =âˆš3xVxIx10-6MVA Short circuit breaking capacity: It is the highest value of short circuit current which a circuit breaker is capable of breaking under specified conditions of transient recovery voltage and power frequency voltage. It is expressed in kA. The breaking current is expressed in two ways
1)The r.m.s value of a.c component of current at the instant of contact separtation.
2)The percentage of d.c component of current at the instant of contact separtation. While selecting the circuit breaker for a particular location in the power system the fault level at that point is determined.
Volume is a pace which can be occupied by some thing, whereas capacity is applies to liquids as the quantity contained in a given space.
Capacity is how 'much' can fit into something, E.g. The capacity of a container may be 2 cups of rice or 500 mL of water. Volume is the amount of 'space' that is taken up (whether or not there is something in it or it is solid), expressed in cubic cm (or m or km). how much can be held.
What is the difference between evaluating an expression?
The difference between a variable resistor and a rheostat is the same as the difference between six and half a dozen.
difference between survey and experiment
CB MCB (i) Mechanism of CB is tripping relay. (i) Mechanism of MCB is tripping release (ii) It is used in HV system. (ii) It is used in LV system. (iii) Rupturing capacity is high . (iii) Rupturing capacity is low.
13amp have a high breaking capacity than 5amp plug
Making capacity of a circuit breaker is the maximum current which the breaker can conduct at the instant of closing. Breaking capacity of the circuit breaker refers to the maximum current that the circuit breaker can interrupt.
Devices such as transistors, IGBT, thyristors in order to protect them the rupture time is in msec. HRC fuses rupture time is more and the current for rupturing is also high making it suitable for motors/resistive loads.
there is no difference.
What is the difference between rated capacity and the nominal capacity
I do not know the answer.The difference between mass and capacity is that capacity is how much something can hold and mass is the weight of an object.
Implantation is usually light and lasts a few hours to a 3-4 days. It is also spotting of a pinkish discharge. Cyst rupturing can only be diagnosed by a doctor.
Capacitance is quite literally the capacity to hold charge at a given potential difference.
storage capacity capacity (mb)
lung capacity/volume: the volume of the air in the lung after maximal inspiration there is no difference
