Presentation

Csepro series offers a multi functional comprehensive smart protection solution for feeder, generator, motor & transformer segment.csepro family of protective relays are advance numerical relays that provide multi protection and monitoring with reliable and fast protection solutions in a single unit.in this family of csepro series, the cseprotxxx is an advanced transformer protection solution which has fast, sensitive and secure protection fortransformer internal & external faults.cseprotxxx also provides an automation solution of power control. It complies with lec60870-5-103, lec6185o, modbus protocol
for high integration of protection & control.

Application :

csepro~t differential relays are used as the main protection and control units for two winding power transformers, for both internal faults and faults in the influence area of current transformers.csepro-t units require no interposing transformers to adjust ct ratio and vector group correction as these adjustments are made by the relay itself in software. For these transformer winding configuration (vector group yd1, –~- dd10) & ct ratio are selectable though l-lml / usb communication. One has to select correct transformer winding configuration and ct ratio used in the protection scheme.
