Distribution Automation Controllers

Multifunctional field RTUs / Distribution Automation Controllers engineered to monitor overhead and underground distribution grids and control MV switching equipment.

Underground Distribution Automation Controllers - CMDA

Underground Distribution Automation Controllers - CMDA

The adaTECH CMDA is a distribution automation controller engineered to control and monitor secondary distribution MV equipment, like Gas Insulated Ring Main Units (RMU), transformer stations, pad mounted gear, vault  / subsurface switchgear and other MV switching equipment installed in a ring / radial topology  .   

Combined with Low Power Instrument Transformers, our DA controller offers an  engineered solution to operate and manage up to 3 feeders / lines, providing real time grid and equipment status data from field to utility level distribution and assets management services.

Its flexibility, low maintenance and compact size make it a reliable solution both to upgrade MV installed Ring Main Units base and enhance new manufactured MV switching equipment.
