versatile meters with the ability to measure 3 to 110 parameters, the opening and closing contacts for control and alarm of the high and low values, has a special place in the panel. Also it can be used for harmonic analysis.
Digital multifunction meters and Power Quality Monitors PQM from Ziegler instruments with multiple parameter measurement is world renowned in the power and energy sector . multi-function panel mount power quality monitor which measures , calculates and displays major , electrical parameters of three phase power system .
this meters are used to measure as The analysis of energy exchange of high-voltage lines, medium voltage and low voltage applications . differences between EMA90H and EMA90 is harmonic analysis function in EMA90H.
In order to reduce power consumption and the related fees and load management skills, the urgent need for a comprehensive and accurate measuring system the main consumers of the plant, as well as collecting and reporting information system measured, felt.
Energy meter with direct three phase connections, type DVH and DDH are used in 4 wires networks and 2 wire networks (with neutral) and 3 wire networks (without neutral) and the maximum input current of them is 65A or 100A.
They are suitable for indoor use only and produced in different models such as DVH 5141,DVH5161, DDH5242, DDH5261-M,...,etc.
Power analyzer with 9 modules, EMA-D9 model is used for measuring, monitoring, management and analysis of the electrical parameters in electrical network. It is mounting on DIN rail and has wide color LCD display and has 9 modules. There is 4 channels of current input in EMA-D9.
