Description

Ground Protection Relay (IPR96D) has been designed to measure the ground RMS current under normal conditions or under disturbances. The current signals are sensed throughout a current transformer (CT). This information is internally processed by the microprocessor in order to take the current protection actions defined under ANSI, IAC or IEC standard. Applications - Primary and backup protection for utility feeder, power plants and industrial distribution systems Protection and Functionality - (50G/50N) Instantaneous ground overcurrent - (51.1G/51.1N) Ground timed overcurrent - (51.2G/51.2N) Ground timed overcurrent - ANSI, IAC or IEC/BS142 curves included: - moderately inverse - normal inverse - very inverse - extremely inverse - definite time Communication - Communication port RS485 - Remote programming of the setpoints - Communication Protocol: Modbus RTU Features - CT rated primary selectable in 5 A steps (5 A to 5000 A) - Ground RMS current measurement - 1 trip relay and 2 programmable auxiliary relay - Control power drop or internal fault relay - Breaker operation & trip failure - Digital input functions: - remote TRIP - remote RESET - remote Aux Relay activation - breaker Status Signalling - LED and LCD display indication - Ground current indication - Indication and storage through a Pop-Up function, of fault conditions and their values
