| Benefits | The C&S Electric CSDPR-V2-300 self-powered relay offers significant benefits in reliability and cost-effectiveness by eliminating the need for an external auxiliary power supply for core protection functions, which is crucial for applications like Ring Main Units (RMUs). The primary advantage is, Relay draws its operating energy directly from the current transformers (CTs) in the protected circuit, ensuring continuous operation even during a main power outage or auxiliary supply failure. It can also be energised from an auxiliary voltage supply (AC/DC), an internal battery, or a front USB port (for configuration), providing flexibility during commissioning and maintenance. The device is designed to store enough energy to trip the circuit breaker even with low current faults It integrates various protections in a single compact unit, including: Over-current (O/C) Earth fault (E/F) and Earth fault high set Unbalance/Asymmetric protection Circuit Breaker Failure Protection Switch on to Fault * Trip circuit supervision * The relay stores the last several fault and event records with a date and time stamp. Its small and compact design facilitates integration into Ring Main Units and other space-constrained switchboards. Features an RS-485 Modbus communication port (rear) and a front USB port for PC/laptop interfacing, enabling remote monitoring, control, and easy configuration using software like CSE LIVELINK. An LCD display and push buttons allow for easy viewing of measured parameters, fault data, and setting adjustments. |

| Introduction | CSDPR-V2-300 is a numeric multi-powered Overcurrent relay specially designed for ring main units & feeder protection. It consists of all the necessary protection and monitoring functions required for RMU. The advanced Controller continuously monitors line load current and E/F currents with standard CTs. These measured values are then used for different protection functions overcurrent protection, E/F protection etc. Metering is available on LCD display. The power module derives power from the current flowing through the line; therefore, external power supply is not required. Relay provides pulse output to Trip the RMU or compact CB having low low-energy series tripping coil. Along with that, Relay provides potential-free output contacts for Alarm/Annunciation. |
