A one stop solution to manage your resources

CEMA SYSTEMS

“Managing competition through cost saving and quality management of resources has caught the attention of many management gurus across various industries. One of the major qualifying criteria is to possess information on your fingertips”

WHY CEMA.…?
Energy efficiency is one such resource, an incredible investment for a sound business vision. Needs can vary from energy inputs to consumption, uptime & downtime, machine utilization and manpower effectiveness. Energy management and proper utilization of power can convert into revenue on a long-term basis.

WHAT IS CEMA.?…
 “CEMA” - Centralized Energy Monitoring and Accounting System an System that helps to Acquire, monitor and Account for energy needs and manage energy consumption, thereby giving you direct access to conserve energy and indirect benefits in terms of avoiding excess consumption, low productivity, excess operational loss, wear & tear, shutdowns & high energy cost.
CEMA comprises of high quality and feature oriented measuring devices connected to your computer or server through a specialized software, giving you instant data & reports on a hourly, daily, weekly, yearly or as and when the need arises. CEMA can track various parameters associated with power, water, steam, gas, air, fuel etc. CEMA tracks these parameters and the quality/flaws from all machines & nodes simultaneously. It provides data on consumption accurately to identify the wastage if any against Universal Standard /Industrial norms.

TOPOLOGY VIEW

Topology view is used to continuously monitor all Electrical Parameters. The parameters can be customized according to the user’s need.
A user-defined background in .jpg format can be deposited, for example a sketch of the existing energy distributions. The measuring devices can now be allocated on the sketch according to their real position, and the selected values can be shown online. Threshold violations are clearly marked with selected colors. The status of the inputs and outputs can also be indicated. Topology view, therefore, allows a fast overview over the complete energy grid with the possibility
to locate interferences, for example caused by harmonic sources, by comparing every single measuring point, and check the customer set tolerances.

TOPOLOGY

Limit can be set for any parameter, thereby an alarm can be generated when the parameter exceeds the specified limit.

GRAPHICAL GENERATION

GRAPHICAL VIEW - ONLINE DATA

REPORT GENERATION

Reports can be generated for all specified parameters.

CONFIGURATION OF MEMORY FOR DATA LOGGING

MEASURED VALUE MANAGER(COST CENTER MANAGEMENT)

In order to offer another low cost solution for cost center management, it offers user defined Excel solutions.  An expensive control technological solution becomes needless. 
The most commonly measured data of products are available as Excel macro or Excel function.
Those macros get the corresponding measured values from the database, generated by PSW professional, and insert those in an Excel sheet.
For example, only time periods are entered, and the corresponding consumption, costs or graphs are given out. For the construction of the Excel sheets, all tools and instruments of Excel can be used. The Excel macro is bound into Excel as an Add-In

GRIDVIS SOFTWARE
Gridvis software is suitable for programming and configuring power quality analysers, power analysers, universal measuring instruments, dataloggers and reactive power controller as well as for the administration and visualization of all measured data. The electrical data from the companies can be monitored at a glance in the topology overviews. The measured values are written in the data memories of the units or directly online in databases and can then be presented as line graphs, bar charts or histograms.

Multifunctional Power Meters can also be programmed through Gridvis software which has the following features:
(A)        Visualization of measurement values
(B)        Automatic ring buffer readout from the instruments
(C)        Storage of the data in a database
(D)        Graphic presentation of online measurement values

1. (F)        Configurable topology overview with freely selectable register levels
2. (G)        Configuration of the measuring instruments
3. (H)        Graphic programming of user programs or programming with the Jasic source code 
4. (I)        Parameterisation, visualization, data management and analysis
5. (J)        Measurement data analysis
6. (K)        Events Browser
7. (L)        Harmonic Analysis

TOPOLOGY VIEW

The Gridvis software for programming and grid visualization enables a simple and complete parameterisation of power analysers. Customer specific visualization of the energy supply is possible with the topology view. The topology overview guarantees a quick overview of the complete electricity network.

GRAPHICAL GENERATION

Graph can be generated for electrical parameters like voltage, current, power factor and cos(phi). Selected values can be supervised online. The measurement data can be directly recorded on the PC in online graphs. Furthermore, Gridvis offers convenient opportunities for presentation and analysis of historical data from the database.

The software Gridvis allows an individual collection, reading out and visualization of online data. The received data of multiple measuring points are collected, saved, processed, visualized and provided for further use. All measurement values are available in the mode of online measurement either as a line graph or bar graph. The Line graphs are permanently actualized and the most obsolete datas are cancelled. Two scales can be created for two different units per graph. Any number of measurement data from each unit, including from measurement instruments, can be observed in the same graph. In the graphs, indication of transients and events is displayed. The colour of the graphs can be adjusted as required.

REPORTING AND STATISTICAL FUNCTIONS

With integrated reporting and statistical functions, the following reports and information can be created, printed on paper or exported via HTML, excel images or as pdf files.

PROGRAMMING LANGUAGE JASIC AND LICENSES

The programming language JASIC opens up completely new possibilities. We are no longer limited to the device’s built in functions, but the device can be extended with your own functions and applications. The graphical programming is used to create and configure logical operations or mathematical functions. We can activate your own digital outputs depending on predefined thresholds for example, and digital inputs are evaluated. In addition it is possible to analyse or write registers of external modbus devices. It is possible to customize the applications according to specific requirements and extend by far the functionality of the measurement devices of the UMG device series UMG 604,UMG 103,UMG 96S,UMG 503, UMG 510 etc. The self made programs can be stored on the computer as a file or directly transmitted to the UMG measurement device. For storage of your customized programs, 7 memory locations are available with 128K-byte memory space available.

CASE STUDIES

LAURSEN AND TOUBRO LTD, PONDICHERRY
Laursen and Toubro Limited has Rolling Mill division located at Pondicherry which manufactures Anglers for transmission lines.

MAIN CAUSE FOR THE NEED OF ENERGY MONITORING SYSTEM
The number of Anglers passing through the rolling mill needs to be monitored.

BARON SOLUTION
The solution was given by calculating the number of times the current shoots as the anglers pass through the load. EMS software is programmed to record this excessive shoot by customizing the current limit in the topology view. Therefore this rise in current gets stored in the software which in turn gives the number of anglers passing through the load.
