The fault is called a catastrophic fault when the faulty element produces either a short circuit or an open circuit. The fault is called a deviation fault when the faulty element deviates from its nominal value without reaching its extreme lower or upper bounds. For diagnosing the deviation faults, a parameter-value determination technique utilizing inverse transformation of a generalized star to polygon transformation is a very promising approach. On the other hand, a fault dictionary technique is suited to catastrophic faults, but it is difficult to construct a good fault dictionary, in which sufficiently large number of possible faults and the corresponding syndromes are stored, because of the variety of faults. In this paper a new approach is presented for the location of catastrophic faults in linear RLC circuits. The approach is based on reviving the weighted underlying graph of a circuit if any edge admittance of the circuit is either zero or infinity.
