Secondary Substation Platform.

The ZIV MV Flexible RTU with its powerful processor and range of communications ports is the core component of any Secondary Substation Automation System.

The module supports all the standard protocols for Control Centre communications including Secure IEC 104, DNP3 SAV5, IEC101 and an extensive range of legacy protocols.

The ZIV MV Flexible RTU also has the capability of operating as the gateway for virtually all substation IEDs using protocols such as IEC 61850 Client & Server (KEMA certified), IEC 101/104, DNP3.0 (TCP/IP & Serial), IEC 103 and Modbus (TCP/IP & Serial).

RMU Controller.

The unit is used extensively as an RMU / Switch Controller based on its size, interface flexibility, fault detection and cybersecurity. The unit supports a wide variety of interfaces for AC voltages and currents including conventional CT/VTs, LEA (Low Energy Analogues), Rogowski sensors, Line Post sensors and other low voltage input ranges. This ensures that it can interface with different RMU / Switch types.

DER Controller.

The ZIV MV Flexible RTU is widely used as a DER (Distributed Energy Resource) Controller based on its DER Management capabilities, setpoint controls, failsafe operation, interface flexibility and cybersecurity.

The unit can operate as a standalone DER Controller managing the power import/export limits from a particular DER site or as part of an integrated ANM (Active Network Management) scheme or both.
