EDR-3000
The EDR-3000 Protective Relay is a multifunction microprocessor based overcurrent relay designed for both ANSI and IEC applications. It is a panel-mounted, self-contained unit which operates from either ac or dc control power. The EDR-3000 design provides true RMS and fundamental sensing of each phase and ground current. Only one unit is required for each 3-phase circuit. Current monitoring and operator selectable protective functions are integral to each relay. The EDR-3000 relay operates from the 5 amperes or 1 ampere secondary output of standard current transformers. The EDR-3000 has multiple setting groups to reduce arc flash energy and zone selective interlocking for bus protection eliminating the need of additional CTs or relays. The EDR-3000 features a user friendly operations panel to monitor, and program the relay. Operating parameters and troubleshooting information are displayed in the 128x64 LCD display. In addition, all data and information can be communicated to a host computer equipped with PowerPort-E TM. |
