THE MID DIRECTIVE
Implemented nationally with Legislative Decree 22/2007 is one of the new approach directives adopted by the European community. The objective of this approach is the definition of shared and common technical rules, which allow the instruments to move freely within the community
e instruments that fall within this standard have the CE marking, and it is important to underline that the directive relates exclusively to the design and production phases of the measuring instruments.
In energy monitoring installations or in those installations on machines with limited space, the dimensions of the instrument are the basis for being able to perform measurements without having to create a new panel.
The QE-POWER-T model is the most compact three-phase instrument on the market, only 17.5mm wide, without display, with integrated RS485 serial communication. The instrument supports any type of current transformers (secondary 1 or 5 A, 333mV and Rogowski probes). Three different versions are available, from basic measures up to quality network measurements. The device requires a low voltage supply in direct or alternating current.
Bidirectional Three phase Energy meter with RS485 Modbus RTU integrated.
In this category we group the largest number of possible solutions, the lowest common denominator being the RS485 Modbus RTU / Modbus TCP-IP serial communication port and the bi-directionality of measurements (4 Quadrants).

The instrumentation for measures of network quality includes different models, by definition those instruments capable of measuring at least the 51st harmonic are defined, but from a practical point of view it is known that most of the problems are present in the first tens.
Doing a network quality analysis also means measuring the THD on the voltage and current channels and counting and measuring the number of interruptions or voltage dips. To do this we have available Transmitters, Analyzers with display,panel meters with graphic display to measure and shown these information.
