ORION Ground Protection Relay

Ground Protection Relay (IPR-D) 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 ground protection for utility feeders, power plants and industrial distribution systems
PROTECTION AND FUNCTIONALITY
◐ (50N/50G) Instantaneous ground overcurrent
◐ (51N/51G) Inverse time ground overcurrent
◐ ANSI, IAC or IEC/BS142 curves included:
○ Moderately inverse
○ Normal inverse
○ Very inverse
○ Extremely inverse
○ Definite time
◐ Overload alarm pickup level
