The instrumentation for measuring the main electrical parameters of a plant is performed by the Network analyzers or Energy meters, the substantial difference being in the quantity of measured variables and how the measurements performed are made available.
PECTECH manages various solutions in stock, all with RS485 serial communication, suitable to meet the needs of every application, from MID certified to panel installations, from simple energy measurements to harmonic network analysis. The offer covers single-phase and three-phase instruments with direct connection and connection via current transformers. and connection via current transformers . The instruments support different types of current transformers, therefore we are able to provide the solution ready to be installed.
Machine tools, production plants, renewable energies, paper mills, steel mills, shopping centers, HVAC and other types of installations, each require specific measures of energy consumption and other electrical parameters of the network, our experience allows us to support you in choosing the best solutions
Energy meters with MID certification are used to ensure that Energy measurements are performed according to the accuracy and safety requirements defined by the European Community.
In all European countries (except Italy) these instruments are used for billing activities. They are widely used in projects for the recognition of energy efficiency certificates (TEE) or in European projects. The SINGLE-PHASE instruments with direct connection from 45 A and 100 A and the THREE-PHASE instruments with direct connection 100 A or with external CTs of 1 or 5 A are available from stock, all equipped with RS485 MODBUS RTU serial communication A 96x96mm panel version is available with Power Quality measurements.

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.

In this category we group the greatest number of possible solutions, the common feature is the RS485 Modbus RTU serial communication port and the bidirectionality of the measurements (4 Quadrants).
THREE-PHASE compact energy meters are available with LED display with external CT with 5A secondary or 333mV input, Transmitters (without display) and THREE-PHASE instruments with graphic display with high performance (Harmonic Analysis and THD) in class 0.5S. SINGLE-PHASE instruments for measurements with external CTs with secondary 1 or 5 A. In addition to the serial output, there are versions with impulsive digital output, alarm threshold and analogue outputs. Versions with internal Datalogger are available to store data locally on the instrument.

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.

BIDIRECTIONAL THREE PHASE ENERGY METER with integrated RS485 Modbus RTU. PANEL VERSION
Panel executions are typically used by panel builders and plant builders as they can be installed during construction. The large display allows the operator to view the data and the operating parameters of the system.
Basic versions are available for essential measurements, MID certified versions (for energy efficiency projects), versions with graphic display with network quality measurements, display of phasors and the waveform graph. All these instruments are equipped with RS485 Modbus RTU serial communication port. The accuracy class starts from 0.5 S up to 0.2 S.
In the case of measurements on storage systems, photovoltaic systems, data centers, telecommunications shelters and other applications related to continuous measurements, the QI-POWER line allows the measurement of DC voltages up to 1000 V and currents up to 400 A DC with a single instrument equipped with RS485 Modbus RTU serial communication.
The QA-POWER-M module allows to have an analogue output, a threshold and a direct input up to 10 A AC / DC and to store the data thanks to a USB memory key to be connected directly on the instrument The QA-POWER-M is equipped with RS485 serial communication and is suitable for use as a signal converter for AC voltages up to 600 V and DC up to 1000 V.
