CSENEX Series offers a compact Multi-functional Over-current protection solution for Feeder, Generator, Motor & Transformer segment. CSENEX-l Family of protective relays are numeric relays that provides multi protection and monitoring with reliable and fast protection solution in a single unit. In this family of CSENEX series, the CSENEX-I 150 is an advanced feeder protection solution which has fast, sensitive and secure protection forfeeder internal & external faults. CSENEX-l offers different model based features to cover the wide range of user.The CSENEX-I relays have been designed for controlling, protecting and monitoring industrial, utility distribution networks and substations. They can also be used as part of a protection scheme for feeders, transformers and generators.Three Phase Over-current Protection (50/51): The independent two stages are available for phase fault protection. For l> the user may independently select definite time delay or inverse time delay with different type of curves. The second Hi-Set stage can be configured with definite time only.Earth Fault Protection (50N / 51N): The independent two stages are available for earth fault protection. For first stage (le>) the user can select definite time delay or inverse time delay with different type of curves. The second Hi-Set stage can be configured with definite time only.
