Hight Numerical Current Relay with RecloserDOA2.1

رله اتوریکلوزر مدل DOA2.1

The overcurrent relay type DOA 2.1 is a numerical relay have been designed to control, protect and monitor industrial installations, public distribution networks and substations, and to be used as back-up protection for EHV and HV transmission networks.

The DOA 2.1 relay provide comprehensive overcurrent phase and earth fault protection for utilities networks, industrial plants and networks as well as for other applications where overcurrent protection is required. The earth fault protection is sensitive enough to be applied in electrical networks where the earth fault current is low. In addition to its protective functions, each relay offers control and recording features. They can be fully integrated to a control system so protection, control,data acquisition and recording of faults, events and disturbances can be made available.
The relay is equipped on the front panel with a liquid crystal display (LCD) with 2 x 16 back-lit alphanumerical characters, a tactile 7 button keypad (to access all settings, clear alarms and read measurements) and 11 LEDs that indicate the status of the relay.In addition, the use of the RS485 communication port makes it possible to read,reinitialize and change the settings of the relay, if required, from a local or remote PC computer loaded with software.Its flexibility of use, reduced maintenance requirements and ease of integration allow the Relay to provide an adaptable solution for the problems of the protection electric networks.
