quench detection system (QDS) for the LHC 600A corrector magnet circuits and 6KA individual powered quadrupole (IPQ) is described. A direct current derivative method is mainly proposed inorder to improve the dependability of QDS. The system uses a numerically derived current derivative. The current derivative is highly filtered inorder to have a stable calculation. This leads to rise of a phase shift and thus the operational range of the circuit parameter is restricted. Transformer based current derivative sensors are in the process of development and they use cut cores which helps in easy prototyping ,control in the performance and also in the installation process. An improved method was adopted to find the best arrangement of the sensing element,.air gap in the cut core to give high mean sensitivity and to reduce the PQF.
