FAQ About Cable / What is the thermal withstand ...
Last post by tacettin - March 02, 2024, 08:20:43 AM
What is the thermal withstand of a cable ?

The thermal withstand of a cable can be determined by comparing the maximum energy at the fault, with the maximum energy the cable can absorb.  The equation for this is:

I^2*t = k^2*A^2

"I^2*t" is proportional to the energy let-through of the protective device
       I - fault current, A
       t - fault duration, S

"k^2*A^2" is proportional to the energy withstand of the cable
        k - adiabatic constant
        A - cable cross-sectional area, mm2

To better understand the theory behind the above, please check The adiabatic equation.

FAQ About Cable / What is the adiabatic equation...
Last post by tacettin - February 23, 2024, 09:59:19 AM
What is the adiabatic equation for cables?

When calculating the fault ratings of a cable, it is generally assumed that the duration is short enough that no heat is dissipated by the cable to the surroundings.  Adopting this approach simplifies the calculation and errs on the safe side.

The normally used equation is the so-called adiabatic equation.  For a given fault of I, which lasts for time t, the minimum required cable cross-sectional area is given by:

t = (A^2*k^2)/I^2

where:    A - the nominal cross-section area, mm2
        I - the fault current in, A
        t -  duration of fault current, s
        k - a factor dependant on cable type (see below)

The factor k is dependant on the cable insulation, allowable temperature rise under fault conditions, conductor resistivity and heat capacity.  Typical values of k are:
