14. 03. 2017 | The MEg44 monitor measures 3 voltages and 3 currents of the DTS transformer at the LV. It provides the functions of recording, electricity meter and voltage quality analysis. It can be fitted with a module recording the switching overvoltages up to 6 kV.

The MEg44 monitor with DIN rail design measures three voltages and three currents of the DTS transformer at the LV level. It provides the functions of recording, electricity meter and analysis of voltage quality, all performed simultaneously. It can be fitted with a module recording the course of switching overvoltages of up to 6 kV.

            In the recording function, monitor MEg44, processes all measured values, evaluates powers, energies and harmonics up to the order of 125. In the function of voltage quality analyser, the monitor evaluates all parameters for measured three voltages and three currents, as stipulated by the standard. When recording events, the monitor, aside from recording the course of URMS1/2 and IRMS1/2, makes an oscillographic record of all measured values of voltage and current.

            The voltage measuring inputs are designed for direct voltage measurement at the LV level. The current inputs are only designed for indirect measurements by means of instrument current transformers. The MEg44 monitor is powered by 12 V DC from a separate UPS, e.g. MEg101.4. The MEg44 monitor can be also connected to the MEg202.5 LTE communication unit, which enables remote transmission of parameterisation and measured data by GSM networks of mobile operators.

                The monitor is equipped with three communication interfaces. The serial USB interface is designed for local parameterisation of devices and storing of measured data. The Ethernet and RS485 interfaces are intended for connection to local networks and for remote transmission of data.
