3 Billing transformers and accessories Q.3 Billing transformers and accessories This section describes the current transformers used in Low Voltage installations and a wide variety of accessories, for both QNA and CIRWATT. Some of the accessories include modems, for example, RTC (analogue) and type GSM, ideal for communications in points where there is no analogue line. Another accessory is the protection device for analogue modems DIN-RTC, universal optical readers for meters, converters, etc. Highlighting the software available. We have the following software: Powerwatt is a remote metering and management software for meters. Softwatt is a program that has been designed for electricity companies, energy merchants and users that have been authorised to program meters for energy billing purposes. PowerPLC is the management and control software of the meters with PLC communications. PowerStudio is a control software that is focused on energy efficiency for the management of products. Q.3 Definition The installation of meters to bill electrical energy requires the installation of current transformers that have been certified by the electricity company. CIR- CUTOR has a wide range of products that can meet the consumer's requirements in each type of installation with the TRMC transformers. This completes the installation of billing meters, in accordance with the market specifications. Likewise, there are various communication methods proposed to guarantee the total control of the remote meter, depending on the nature of each installation. Analogue and GSM modems are vital elements in remote metering processes. The availability of a dedicated telephone line will allow us to select the type of modem that will be installed. In the case of field metering activities, CIR- CUTOR has meters with an optical port to download the information. The use of the PC's software is vital to download and treat the information stored in the meter's memory. CIRCU- TOR offers different types of software for each application, in order to cater for the customer's needs, from programming to data treatment software. The software range also includes the management of our QNA power quality analyzers, with a powerful application used to control the information, allowing the download of the memory to carry out studies about the behaviour of the grid in each installation. Q3-3

4 Q.3 Billing transformers and accessories Applications Data is downloaded and treated by the meters of the CIRWATT series with various options, depending on the typology of each installation. There is an exclusive telephone line that requires the installation of analogue modems to read the meters. However, if their location means that the installation of a fixed analogue line is improbable, a GSM modem must be connected, with greater accessibility options, since it does not need an additional installation to carry out its functions. CIRCUTOR offers specialised software, such as the SoftWatt range, focused on the operations of electricity companies and energy distribution companies, to program and meter all electrical energy parameters. Watt Pro includes the simulation of bills of the current electricity market, in order to carry out adjusted studies about the cost of electricity bills. Our range of analyzers of the QNA-400 series enables many different grid configurations: RS-232 / RS-485 / Ethernet and GSM-GPRS. PowerVision has been designed to meter the parameters that define the quality of the grid in an installation, while acting as grid analyzers, and it is capable of creating graphs and lists with any electrical parameter required to make a complete study of the grid's behaviour in any industrial environment.

Display of parameters in real time: It displays the parameters of all units in real time, knowing the installation's behaviour and status of the electrical distribution lines of the installation at all times. Said communications are possible, since PowerStudio SCADA is in constant communication with the units (pulling). This information is used to display the evolution of any electrical or process parameter in time, also displaying the increase of totalized variables in time (energy). The user can print any graph or table generated by the software. Alarm module: The previous programming tasks are used by the user to display any incident in the installation in real time. Data can be displayed in digital (number) or analogue (bars) format, indicating the colours (red, orange, green) of the variables that are outside the limits. Record log: Alarms can be associated easily to any parameter available in the PowerStudio SCADA, such as electrical or process parameters, with the purpose of guaranteeing the excellent efficiency of the installation's preventive maintenance tasks. The record log is drawn up as follows: The user must not configure any other option than the storage period to start the recording process, since when the devices are added to the software, PowerStudio SCADA automatically starts recording all electrical parameters Multi-position Software (Integrated Web Server) The internal software web server can be used by any user connected to the corporate network (LAN) or any Internet connection (if the Q3-30

Performance router used for the connection by the company, factory, etc. is connected. The relationship between the public IP and the private IP) to display the data log or in real time, which will be updated permanently. Screens are dynamic, so that the web client can display all data in real time, as in the case of the master server. the installation in each case. Force variables (Remote control) Execution of remote control functions on elements of the installation, forcing stops and start-ups of the said elements. Generation of reports and receipt simulator The number of web users that can connect to the server is unlimited; in the case of the connection, an access filter can be used, limiting the display of screens or with the remote control of the different field elements. Integrated XML and DDE server In addition, there are tools specialised in the exchange of dynamic data, for the integration of the energy supervision tasks within a global control system, which contains communications servers for the integration of DDE (local integration) and XML (relocated integration). Construction of customised screens PowerStudio SCADA can be used to create customised screens that emulate a production process. Therefore, we can fix the parameter or state display labels, which indicate the status of a specific point of the installation or state of a line. The number of screens implemented can be unlimited, so that we will can customise displays in sectors, displaying a specific point of This software has a very powerful module that can be used to generate reports and simulate receipts. It can be used to create billing calendars, programming the following: types of hour, types of day, billing calendars and calculation of costs. This module is used to design a summary report with any variable obtained and recorded by the software. It implements energy consumption in a determined period of time, summary of events or incidents in the grid. The reports can be customised in each case and mathematical functions can even be applied to the variables obtained, with the purpose of obtaining production ratios or to check the consumption of electrical bills issued. All in all, it is a highly versatile and easy to use software. In this case, Scada applications can be created without the need to have programming knowledge, since the user interface uses a vertical menu system. Q3-31

Additional information DYNAMIC EXCHANGE OF DATA PowerStudio Scada, is not only an excellent energy manager, but it also has a series of data exchange functions implemented, facilitating the quick and comfortable integration of the system with other market applications. To carry out the DDE integration tasks, PowerStudio Scada and the generic control application must be installed on the same platform (PC), with a local integration of all parameters requested. XML Integration DDE Integration In many cases, there are clients that not only need to know the CVM grid analyzer, CIR- WATT or protection equipment data, but also need to centralise the air-conditioning or other parameters from the equipment of different manufacturers. The handicap for integrators is the development of different communication drivers for all units connected. To this end, PowerStudio Scada uses a DDE server for the integration of the different units manufactured by CIRCUTOR, acting as a real time integration agent, for the different electrical or process parameters. The objective of the integration of DDE is to facilitate the integrator the indirect communication with units through PowerStudio Scada, with the purpose of assuring a quicker and simpler integration, thus ensuring that the integrator will not have to develop the communication driver for all metering peripherals. At times, integrators have various external applications that need the to read the data from the same peripheral device remotely. This is a big problem, since the units with RS-485 communications can only be queried by a single master. When there is more than one, there are collisions in the communications and no application receives the information correctly. The XML communications protocol solves this problem: the only requirement is that the IP address of the slave application or data server can be accessed. With this format, we can request any electrical or physical parameter of the PowerStudio Scada system in real time, integrating many different electrical or physical parameters in one or various PowerStudio Scada systems installed in the same network, even on accessible external grids (decentralised energy control systems). In other words, the communication between software, via LAN or the Internet. Q3-32
