DMC900A3S0

Automatic Control Panel DMC900A3S0

Thytronic Protection and Control Panels can be mounted both on the MV section supports and on the HV user line of Primary Substations. These devices are applicable not only in medium voltage nodes but also in primary substations with a grounded neutral or with a very low-value neutral resistor in foreign countries where ENEL is present.

Features of the DMC900A3S0 Automatic Control Panel

In addition to protection functions, the DMC900A3S0 automatic control panel provides monitoring and control funcionts such as CT Supervision(74CT),  VT supervision (74VT), trip circuit supervision (74TCS), Syncrocheck function, frequency protection EAC (Automatic Load Balancer), programmable logic (PLC), and automatic reclosing (79).
Calibration, programming, and reading of measurements and recordings can be managed via a PC with ThyVisor support software or through an Ethernet communication bus. All these operations can also be performed through the front keyboard (MMI). Additionally, up to 2 external RIO DMRIS0 modules can be integrated. The system complies with ENEL DMI 900016 and GSTP101 standards, as well as cybersecurity standards. Moreover, an upgrade kit is available for ENEL panels,  to comply  with the latest Enel specifications.
