PDZI9000

Catenary protection - 25 kV or 2x25 kV

Protects 25 kV or 2×25 kV AC catenary systems at 50 or 60 Hz.

Embedding various protection functions, including a distance function [21] combined with a large event recording capacity, our PDZI9000 facilitates the operation of your AC railway electrical network.

Thanks to its hybrid acquisition via CTs or IEC 61850-9-2 «Sampled Values», it is now possible to protect catenaries operated in parallel connected to the same transformer by means of a patented summed current management.
