10.2 Premier 300 installation procedure Having selected a suitable mounting position for the meter, install the meter using the following procedure:

10.2.1 Groundwork 1. Ensure that all the necessary tools are available. 2. By visual inspection, check for any loose or exposed electrical connections near the installation location. If required, secure the loose connections or use fast-drying, commercially available insulation coating to cover exposed connections. 3. Check and label the polarity of the supply to the consumer circuit. Polarity test can be performed by a line tester. A live wire should cause the tester’s LED to glow whereas the neutral wire should not. 4. Ensure that the consumer’s installation is safe for isolation. Check the health status of fuses, cut-outs etc. 5. Isolate / disconnect the consumer’s supply before installation of the meter. 6. Check for the correct cable size. 7. When multiple meters are being installed next to each other on a central panel, ensure that correct position is located for each consumer’s meter. Label the meter accordingly. 8. When the meter box is provided, fix the meter box first and then proceed with the installation of the meter. 9. Remove both extended and secondary terminal block cover of the meter.

10.2.2 Mounting the Premier 300 The meter has two mounting holes each of 5.5 mm in diameter in the terminal block and a key slot at the top centre-line on the rear plate. Steps to fix the meter in position: 1. Mark out the meter fixing position on the mounting surface, drill a hole and fit a ST 4.2*19 mm AB fixing screw keeping approximately 5 mm outside the surface to secure the meter in place 2. Ensure that the recommended screw is tightened at the correct mounting position. 3. Hang the meter from the top mounting hole provided at the rear panel of the meter. 4. Mark out the positions for mounting screws. Refer mounting dimensions given above or mounting template available at the rear of meter packing box. 5. Remove the meter from the top mounting screw and drill out the holes for the bottom mounting screws. PUBLIC


Page 25 of 41

6. Re-hang the meter from the top mounting screw, and then fit the bottom mounting screws. A pairs of mounting holes is provided adjacent to the terminal block which can be used for fixing the meter. These are visible on the front after removing the terminal block cover. Refer to the Table 8 for more details.

10.2.3 Preparing cables for termination 1. Ensure that a cable of the correct rating is being used. If a cable of lower rating is used, replace it with appropriate cable. 2. Strip the insulation of cables used as per given recommendations. Following table shows the internal bore diameters of all the terminals. Meter terminal

If the cable is corroded or oxidized, replace the entire cable. 4. If cable was already stripped for a previous installation, cut /trim the previous stripped length. Reprepare the cable termination. 5. Loosen the terminal screws and insert one cable core into the terminal cage. 6. Ensure that at least 5 mm of the insulated part of the cable core is inserted into the terminal box shroud. If the cable insulation is thick enough to be inserted into the shroud, strip an extra length of 5.00 mm and insulate this extra length with a standard insulation tape to prevent exposed conductor at terminal end. Terminal block shroud will work as an insulation sleeve. 7. Prepare each core in the same manner for supply as well as load side

10.2.4 Making connections Local best practice must be observed when selecting conductor size and type. Making connections to Premier 300 is similar to electromechanical meters. Copper multi-strand conductors should be used for making connections and the following table gives the recommended guideline for using the maximum and minimum conductor size:

4.0 mm2

5 - 10 A

2.5 mm2

6.0 mm2

Premier 300 is equipped with an extended transparent terminal cover, and is intended to be used in installations in which all the cabling is concealed; it is therefore not necessary to use double-insulated cable. The cables must be cut and trimmed carefully. The insulation must be cut back, removed ‘squarely’ ensuring that no copper is exposed on the portion of the cable outside the conductor bore. Particular care must be taken to ensure that all the conductor strands are contained within the conductor bore and secured firmly with conductor screws. Approximately 20 mm conductor should be cut back when the cable is trimmed. The connections should be made as per the connection diagrams shown in Annexure-A depending on the meter type. A suitable connection diagram is shown on terminal block cover of the meter. The process for fitting the conductors is as follows: 1. Insert each conductor core into the appropriate connection cage. Insert each cable into the terminal box shroud. The terminals from left to right are 1S, 1L, 2S, 2L, 3S, 3L, NS, NL. Connect load side first i.e. 1L, 2L, 3L, NL and then the supply side i.e. 1S, 2S, 3S, NS.

Figure 11: Terminal block indicating all the load terminals of Premier 300 with additional RS485 2. Refer to the table below for the recommended torque. Use a torque screw driver to tighten the screws. Tighten all the terminal screws in turn using a torque screw driver. Tighten the lower screws first, followed by the upper screws. Check tightness of lower screw after tightening the upper screw. Check for any loose connections and tighten them, if any. 3. Tightening the screws causes the cage clamp to grip the conductor more tightly. Tightening both screws ensures that the force is distributed correctly. S. No.

Table 13: Class A, B and C Energies Supported Note: Based on customer requirements other type of energies can be added/deleted to the default mentioned list which is as per DLMS Indian companion standard. Energy channels are configurable at the factory end. For all selected energy channels, two different sets of energy registers are maintained in the meter’s memory: 

Current cumulative values



Billing cumulative values

11.2 Fraud Metering In fraud metering mode, Premier 300 computes energy based on I maximum and V nominal as follows: Fraud energy = 3 x X x I maximum x V nominal Where, X is a specified percentage of the rated maximum load taken into account for fraud metering and remains the same for all tampering events for which fraud metering is enabled.

11.3 STOD/TOU Premier 300 supports STOD (Seasonal Time of Day) based energy management. The following table describes the STOD components supported by Premier 300. S. No.

STOD components

Details

1

Rate registers

A maximum of 8 rate registers can be defined for each supported energy type for both current set and billing; for configured energy channels

2

TOD MD registers

A maximum of 8 TOD MD registers can be defined for supported energy types for both, the current and the billing set.

3

Universal demand register

A universal MD (UMD) register is maintained for both current and billing.

4

Day types

Multiple day-types can be defined. A day-type is defined as a combination of several time intervals spanning 24 hours, each assigned to a specific rate register.

5

Seasons

Multiple seasons can be defined. A season is a non-overlapping period with a start date and an end date. Each weekday of a season is linked with a specific day-type. Table 14: Some STOD components in Premier 300

Using these five components, very flexible STOD tariffs can be created. The day types are configurable at factory end.

11.4 MD Reset Upon MD reset transaction, all maximum demand registers are copied to respective billing registers with occurrence time and date stamp. Current registers are then reset. In case mains supply is absent, the scheduled billing (on billing date) happens when mains supply is restored. MD reset can be done through following mechanisms – 1. Pressing the left push-button, if configured through tool 2. Arrival of billing date 3. Change in STOD tables 4. MD reset command If the transaction happens in the middle of current DIP, the on-going demand computation is not reset. The demand is computed at the next DIP cross over. Premier 300 supports and logs MD reset (through a message). It also displays the cause for an MD reset operation.

11.5 Power-off duration, Tamper count Premier 300 also supports power off duration and tamper count.

11.6 Billing For Premier 300, billing operation is triggered through following actions: 1. Through MD reset message 2. Arrival of billing dates 3. Significant change in configuration 4. Pressing left push button PUBLIC


Page 33 of 41

Upon billing, the following information is stored in the history billing data 1. Values of the main energy registers 2. Values of the rate registers 3. Values of the MD registers 4. Time and date of billing action 5. Average power factor between two consecutive billings 6. Power on and off hours In addition to the above parameters, following billing-wise registers will be maintained by Premier 300 for both display and meter readings – 1. Cumulative tamper count 2. Power on and off hours Up to 12 sets of history billing data can be stored in roll-over mode.

11.7 Maximum demand Premier 300 can be configured through the BCS to record maximum demand for any two of the selected energy channels. The demand integration period (DIP) for calculating demand can be selected as either 15, 30 or 60 minutes.

11.7.1 Method of MD Calculation Demand is calculated by the meter at the end of each fixed integration period or DIP as selected by the user. If this value is greater than the already existing value then this is stored as the MD along with the date and end time of the DIP. The maximum value of demand can occur at any time during a DIP, but the Premier 300 logs the MD occurrence time as the end time of that respective DIP. For example, if the maximum value of demand occurs at any point of time ranging between 2:30 to 3:00 PM, then 3:00 PM is logged as the MD occurrence time. Only one MD register can remain active during an interval.

11.8 Metrological output Premier 300 supports two metrological LEDs. One LED blinks based on active energy while the second one (on the right) is configurable for different functions. Push buttons are used to configure the blinking of the right side LED as per the consumption of reactive or apparent energy. Upon scrolling and releasing a button on either a reactive or apparent energy, the LED’s blinking switches to the displayed energy after display time out. On power up and midnight crossover, blinking of the second LED reverts to its default energy. The default energy for the second LED is configurable.

11.9 Time set Upon requests to change the meter time, irrespective of the amount of change required, Premier 300 sets the meter clock to the new time. The existing day of load survey is closed and a new survey day is started from the new date and time.

12 Event Logging Apart from logging electrical energy and billing data, Premier 300 can also be configured to record a pre-defined operating or electrical conditions identified as events. These events become handy to detect different conditions such as attempted tampers and electrical condition monitoring. Premier 300 detects and logs such conditions with special logics built into the metering software. The meter logs an event for both occurrence and restoration of any event. For occurrence, an event is logged if it persists for a duration greater than a pre-defined time identified as ’persistence time-occurrence’. Similarly, when the conditions return to normal and stay normal, the meter logs an event after a predefined period identified as ’persistence time-restoration’. Once recorded, an event can be made available in the meter readings The monitoring functions in Premier 300 allow displaying, logging and communicating different conditions of the meter to the user. These can be categorised as follows S. No.

Function

Details

1

Instantaneous value

Instantaneous values for different electrical parameters such as voltage, current, power factor, power, frequency are displayed on the meter and are also communicated through meter readings.

2

Events

Events are logged for either one or a combination of multiple predefined operating or electrical conditions. Premier 300 detects such conditions and stores them with occurrence and restoration time. Events are logged and are available in meter readings.

3

Load survey

Load survey is the demand value logged for every consecutive 15, 30 or 60 minute intervals, also identified as ‘Survey Integration Period’ (SIP). Table 15: Event logging in Premier 300

12.1 Event Categories Premier 300 can log the events based on the following categories: Voltage Current Power Transaction Others Non-rollover events such as Cover Open Other Comms Events Non DLMS Events An event is logged in a pre-defined area of memory, also known as a compartment, configured while building the tariff through the tool. Eight configurable compartments for event-logging are available in Premier 300. Generally, only one type of events can be accommodated in a particular compartment. The size of a compartment depends upon the configuration through tool. Events in a particular compartment may or may not be logged with snapshots; this is configurable through the BCS for a complete compartment and not for each event type in the compartment. Note that the compartment containing power on and power-off events does not have a provision of logging snapshots. The number of events configured directly affects the capacity to hold load survey. Higher the events, lesser is the space for storing survey data.

13 External Communication 13.1 Active mode In active mode, half-duplex asynchronous communication is supported through two communication ports – IEC 1107 port and RS-232. While the default baud rate for is 9600 baud, Premier 300 supports only the DLMS protocol for communication in active mode. A secure link must be first established between the server (Premier 300 in this case) and the client (like BCS). All communication is standard OBIS code profile based where a client queries for required information in the form of standard OBIS codes. The server then responds to those OBIS codes in a standard profiles. Default password for meter readings is ABCD001. A complete standard meter reading comprises of four reading sessions as under -

13.1.1 Meter readings – Instantaneous session Instantaneous parameters are read through this session.

13.1.2 Meter readings – Readings session This session is read billing-set wise – current and history bill-sets can be read through the standard readings. Selectivity is enabled for reading desired sessions.

13.1.3 Meter readings – Load survey session Either the whole or selective (subject to availability) load survey readings are available in Premier 300. It is possible to read load survey data from a defined SIP on a particular earlier date to a desired SIP on some other earlier or current date through the standard readings. You can read load survey using fixed or sliding window methods. To know more about the sliding window concept refer section 11.7.1.

13.1.4 Meter readings – Events session In this session, events information available in Premier 300 is read in the form of standard event profiles. Each event log has a separate profile and log profiles are read sequentially. Selectivity is available for reading session for desired event.

13.1.5 Load survey / Interval data Load survey data is configurable through at the time of customization with all instantaneous and energy parameters available. Premier 300 supports fixed-window and sliding-window type load survey data with energy and instantaneous parameters for 15 / 30/60 minutes survey integration period, SIP. Up to 700 parameter-days of load survey data with 30 minute SIP is available in Premier 300 LT and 900 p-days in Premier 300 HT.

13.2 Security Premier supports security configuration for allowing access to authorised personnel only. The security mechanism provides configuring security at the following levels: LOWEST LEVEL for Public Client LOW LEVEL for Meter Reader HIGH LEVEL for Utility Settings

13.3 Sub-active (SA) Mode Under sub-active mode, Premier 300 operates in the absence of mains supply on battery backup and supports limited meter and display read features. The meter supports the following functionality in the sub-active mode: Meter reading using optical 1107 port in DLMS mode Manual display Manual Display The supported displays and display functionality is different for active and sub-active modes. A separate page needs to be configured for ‘manual’ display parameters in the sub-active mode. During a power down, only up to 3 activations are supported; further invocation of sub-active mode is prevented until next power up. Also, a single sub-active mode operation cannot last longer than a few minutes. NOTES: Sub-active mode can be used only for a small duration in any given month. Upon exceeding the monthly limit, the firmware disables sub-active mode operation until the start of next month. The timer is then reset to keep a log of the time of sub-active mode use for the new month. No transaction will be allowed in SA mode such as MD Reset or time set SA mode does not support push button long press
