EOR-3DS
EOR-3DS - Fault location in analog as well as in digital primary and secondary substations.
The Earth Fault and Short Circuit Indicator EOR-3DS is intended for fixed installation and the continual measurement, monitoring and evaluation of voltages and currents. The EOR-3DS is exclusively intended for use in electrical power engineering facilities and installations, where professionals carry out the necessary work.
The EOR-3DS combines earth fault and short circuit detection in a compact device. The advantages of different locating methods can be used and weighted by prioritization. The device is developed for the detection of a single feeder. By a variety of SCADA protocols, a PLC functionality, the use of mono-stable relays and IT-Security features the EOR-3DS is especially suitable for installation in intelligent switch gear stations.
