Railway electrification is the main trend of this last century. Although the deployment of overhead lines is keeping growing, specific protection devices are needed in the substation to detect and disconnect damaged or fallen catenaries. The associated problem is how to test those protections with a high degree of confidence, while reproducing as closely as possible the potential catenary damage.

The IDC20K revolutionary DC current injector is able to reproduce this kind of electrical faults with an ampacity of up to 20 000 A. By introduction of the catenary parameters and fault characteristics, the IDC20K is able to generate a current waveform identical to a line fault. It allows secure, low voltage testing with accuracy.

IDC20K brings operators a new and innovative way to perfectly master their protection devices and get more confident in the protection of their network.
