Enhanced hardware for demanding applications The Extended is the Thytronic high level platform for the comprehensive protection in distribution networks, substations and industrial plants with any level of application: selective protection of feeders, power transformers, motors, generators, bank capacitors inside large industrial plants (Oil & Gas), metallurgy and paper industry and offshore installations. INNOVATIVE FEATURES More binary I/O without external expansion modules More communication ports with redundancy and TX (RJ45) and/or FX (optical ber) connections IRIG-B Synchronization with...

VERSIONS NVA100X-B (BASE) The protective system for a feeder and a transformer is largely dependent on the size and the importance of the transformer. In case of transformers the usual practise is to provide overcurrent delayed and instantaneous protection for overloads, external short-circuit, terminal faults, winding faults. NVA100X-B is suitable for all these application and, moreover, also for protecting feeders and transformers from earth fault in case grounding through impedance, solidly earthed or isolated. Phase-to-phase faults, interturn faults, core faults are the other typical cases....

COMMUNICATION The evolution of the supervision and control systems in the electrical systems requires the possibility of setting up the protection relays as intelligent devices (IFD – Intelligent Field Devices) within communication networks consisting of general purpose devices such as PLCs or Personal Computers. To meet this need, THYTRONIC has geared its development strategy towards the search for “open” solutions: the Extended family provides communication protocols based on Ethernet technology such as MODBUS TCP/IP and IEC61850. These protocols allow the use of a single eld bus with all features...

PROTECTION AND CONTROL ELEMENTS The protection elements are grouped according to typical applications as shown in the table below, but more combinations are easily achievable thanks to the configurable Hw-Sw structure of the PROMM Extended family Some versions (NVA100X-P) can be supplied with CT and VT or sensors (ThySensor) input circuits.
