1 Safety

1.1 Safety requirements

1. Installing, uninstalling, parameterization and verification can be performed only by authorized organizations that have qualified technicians. Only qualified persons should install meters.

2. Meter’s connection or disconnection from network should be done when voltage in the network is turned off. A protection from accidental network voltage connection must be established.

3. No accessories can be hung on a meter, it is forbidden to hit or strike meter’s case.

4. Precautions must be taken in battery changing procedure: 1) meter has to be disconnected from electricity network, a protection from accidental network voltage connection must be assured; 2) use pincers or similar instruments to change battery (connection/disconnection of a plug).

1.2 Transportation and storage rules

1. Prior to the usage meter must be kept in a closed room in a transportation packing, where the temperature ranges from 5°C to 40°C and average area humidity is up to 80% when temperature being 25°C. The room must be without harmful gas or steam. Meter must be kept and exploited in premises protected from dust, aggressive vapors and gas.

2. Unpacked meters can be kept only in repair workshop. The temperature must range from 10°C to 35°C, average area humidity must not exceed 80% when temperature being 25°C.

3. During wintertime meters must be kept in a heated room for 6 hours or more, before they are used.

4. Meters are to be transported only in closed vehicles (carriage, container, hold). Shake acceleration is to be up to 30m/s², 80-120 strikes per minute. The temperature must range from -40°C to +70°C, average area humidity must not exceed 98% when temperature being 35°C.

1.3 Prevention and elimination of malfunctions

If suspected that meter works improperly, the following actions should be performed:

1.3.1 Exterior inspection

Before applying voltage to the meter makes sure its case has no mechanical damages, there are no signs of overheating, and all wires are properly connected.

Do not plug a meter into network if it is mechanically damaged. This can cause

staff injuries and destroy meter as well as other equipment!

Before switching on network voltage, it is necessary to check if sliding voltage

link is connected (see chapter 5.7 Sliding voltage link).

1.3.2 Inspection of connection and parametrization constants

Installing, uninstalling, parametrization and verification can be performed only by authorized organizations that have qualified technicians. After plugging a meter into electric network technician should check whether date and time are correct, whether meter shows right energy direction, valid tariff time zone and calendar, tariff seasons.

1. If meter shows wrong date and time, a representative from the organization in charge of the meter installation should be informed.

2. If LCD indicator shows a warning note ‘Er’, the meter should be uninstalled and passed for repair works.

3. If energy direction is wrong, technician should check whether inputs are connected properly to terminal block.

4. If meter calendar season, season time name or valid tariff time zone does not correspond to real situation, meter’s parameterization data has to be checked and errors has to be corrected by repeated meter’s parameterization.

1.3.3 Procedure of meter returning to manufacturer

In case malfunctions cannot be eliminated on the spot, the meter should be returned to the manufacturer for repair or replacement. Meters on their return to manufacturer must have their Passport with notices of organization in charge of their exploitation and short description of meter’s malfunctioning.

Harmonics analysis is performed by using a digital band-pass filter, tuned to 50 Hz (narrow band). Total Harmonic Distortion (THD) for current and voltage is calculated by formulas:

Wide band RMS values are measured up to 21st harmonics (21 × 50 Hz = 1050 Hz). Maximum demand registration is explained in chapter 7.3. For more information about billing profile refer to chapter 8.1. List of measured instantaneous values is presented in Table 4-4. Instantaneous data can be readout via all available communication interfaces. Please note: meters that do not contain reactive energy registers (Code F3), do not measure instantaneous reactive power, as well as power factor cos(φ). For more information about load profile refer to chapter 8.2.

5 Construction

5.1 Case

Meter case, fixing holes and terminal block conform to the requirements of standard DIN 43857. Meter case can be made from transparent highly mechanically resistant and fire retardant insulation material – polycarbonate, stabilized by ultraviolet rays or molded of non-transparent polycarbonate with transparent polycarbonate windows for LCD, optical interface and optical test output. It protects meter interior parts and its nameplate. Main cover (transparent and nontransparent parts of main cover) is fixed to the base by two sealing screws. Removal of main cover of mounted meter could be done only after terminal cover removal. An option of special sealing bolts preventing disassemble of meter is available. Terminal cover is fastened with 1 sealing screw (suspended seal). Access to the terminals without terminal cover removal is excluded. This affords additional level of security to the customer. Terminal cover has a hole for threading sealing wire to sealing screw. The possibility to touch the meter terminals with sealing wire while sealing the terminal cover is prevented. Figure (See Figure 5-1) presents meter exterior parts and allotment of control elements. For case dimensions and allotment of fixing holes see Figure A-0-1. There is a liquid crystal display (LCD), optical communication interface, optical scroll key for display control, sealable and not sealable buttons on the main cover of the meter. See chapter 11 for the explanation of display control commands, and chapter 6.10 for the description of push buttons.

and non-transferable. Nameplate for meters with non-transferable cover is marked on the nontransparent part of main cover by means of laser marking technology during the meter manufacturing process. This ensures that all marks and inscription are clear, non-erasable and non-transferable. The nameplate bears all the necessary information according to EN 50470-1 and Directive 2004/22/EC, as well as identification of main data, displayed on LCD. Example of nameplate is provided in Figure 5-3. Meter serial number is displayed as barcode (by default, barcode type Interleaved 2/5). Additional QR (DataMatrix) code which contains the meter technical information is printed on the nameplate.

5.3 Terminal block

The terminal block with all meter connections is situated behind the terminal cover. Terminal block made from highly mechanically resistant and fire retardant insulation material and conform to the requirements of standard DIN 43857. One utility seal in the fixing screw of the terminal cover prevent unauthorized access to the phase connections and therefore also prevent unrecorded energy consumption. Current and voltage terminals can be made of zinc-plated iron or nickel-plated brass (copper) and it provides the ability to add copper or aluminium wires without oxidation process. Terminal assures the same quality of the contact irrespective of the shape of the connection conductor (a compact wire, a stranded wire, greater or smaller cross-sections).

Current terminals for current up to 100 A are with 9 mm hole diameter and wires cross sectional area at 2.5 mm2 to 60 mm2.

5.4 Operation principle

5.4.1 Measurement module

In measurement module, current and voltage values of each phase are transformed into proportionally analogous signals. Precise current transformers, shunts or di/dt current sensors are used for current measurement in phase circuit. In case meter contains two measurement elements (i.e. type G1B.x6x carries out current measurement in neutral as well), current measurement in neutral circuit is based on different type of current sensor (current transformers or shunts). For voltage measurement, resistant voltage dividers are employed.

5.4.2 Signal conversion

Analogous signals are transformed into digital codes by three-channel Sigma - Delta converter. Digital signal processor (DSP) calculates average power values P(t) and Q(t), as well as instantaneous RMS values of current and voltage. Furthermore, DSP outputs values of RMS current in neutral and electricity network frequency.

5.4.3 Micro-controller

By integrating power values, micro-controller accumulates import and export energy values. Energy values are registered to corresponding energy and demand tariff registers in accordance with the valid tariff program. Furthermore micro-controller controls liquid crystal display, communication interface, meter outputs, tariff program and internal clock.

5.4.4 Non-volatile memory

G1B meters contain non-volatile flash memory of different capacity (2048 kB). Flash memory is used for data profiles and parameter storage. Memory retains data for 20 years and more.

5.5 Display (LCD)

Gama 100 meters are provided with a liquid crystal display (LCD). The display can be provided with backlight for easier reading (read chapter 4.8). LCD backlight may be configured (only by manufacturer) for one of two work modes and can work permanently or can be switched on by

pressing one of the buttons and is extinguished automatically after a short time if no further button is pressed. LCD backlight can be switched on and turned off locally or remotely. Default liquid crystal display of G1B meter contains 115 controlled segments (marked in dark colour in Figure 5-5 - Figure 5-7). Vertical dimension of main digits is 10 mm. LCD displays majority of data accumulated in meter and parameterization constants. LCD divided into 7 information fields which description is not changeable and
