CMM-R6D
Multifunction measurement center

CMM-R6D is the ideal solution for monitoring transformer stations and TGBTs. It allows for measuring the main electrical parameters of the network, ensuring bidirectional energy counting, and measuring earth leakage current, ambient or contact temperature, in addition to remotely controlling and reporting device states. Moreover, it enables the separation of active and reactive energy consumption from the "Normal" network from those produced by the backup generator.

Description

The CMM-R6D measurement center allows for measuring the main electrical parameters of the network, ensuring bidirectional energy counting, and analyzing some parameters of electrical signal quality. It is equipped with a ground leakage current measurement input and a PT100 temperature measurement input. It can also be equipped with a module of 4 TOR inputs and two relay outputs for the control and monitoring of field equipment. The device also features a power measurement function for the backup source, which can be triggered by an external signal It can be easily integrated into any supervision system or energy management system to monitor installation or energy quality.

It is primarily intended for monitoring electrical substations (transformer substations) and for energy management and monitoring of electrical installations requiring mounting on rails (distribution panels in tertiary or residential buildings), mounting in drawers of detachable panels (mining industries, etc.), monitoring of generators and motor starters with measurement of earth leakage current and equipment temperature measurement (generators, capacitor banks, MCC panels, machine tools, ovens, etc.), etc.
