  • Page 37: Instant Values

    These registers cannot be reset. 7.3 Instant values Besides energy, the Prometer 100 can also measure instant values. Instant values are constantly changing values such as current, voltage, power and harmonics. The instant values are updated every second. The formulas and definitions used to calculate the values are presented in Appendix E: Calculation Principles on page 61.

  • Page 38: Prefix For Units In The Display

    7.4 Daily Energy Snapshot Energy Snapshot feature saves the value of a particular energy register at a particular time. Prometer 100 stores a snapshot of different energy registers (can be up to 28 energies) on a daily basis at predefined time as selected from tariff configuration (generally it is set at midnight).

  • Page 39: Digital Inputs And Outputs

    7.5 Digital inputs and outputs The Prometer 100 has several inputs and outputs that can be configured to perform various tasks. Both inputs and outputs are protected against overvoltages by varistors. They also have an isolated interface between the electronics and the surroundings to ensure personal safety. For electrical data on the meter’s inputs and outputs, see Appendix F: Connection and General Details (page 66).

  • Page 40: Outputs

    Note that the outputs are inverted via firmware. If the meter loses its auxiliary power, the relay will open, regardless of it is inverted or not. Page 40 of 72 Prometer 100 User Manual BGX501-943-R01...

  • Page 41: Communications And Security

    An active output means a closed relay when the output is not inverted. When the output is inverted, the active relay is open. The Prometer 100 outputs are of the solid-state type and when the meter is turned off, they are open.

  • Page 42: Loggers

    7.7.1 Overview A logger in a Prometer 100 can log values for instant quantities, energy registers and external registers. Some quantities can be logged both by phase and as total values for all three phases, others only as total values. The table provides an overview of quantities that can be logged.

  • Page 43: Logging Interval And Total Channels

    A logger’s capacity is dependent on number of channels and logging interval. For example, Prometer 100 meters can be configured to store 960 days of load profile data at 30 minutes SIP for 10 parameters. When the logger is full, the oldest values will be written over. The table shows the capacity in number of days before the oldest value is written over.

  • Page 44: Storage Of Logged Values

    When a user-defined alarm has triggered during the past interval, this is indicated with the flag “Alarm”. Parameter The Prometer 100’s configuration, calibration or initiation has changed. Which of changed these three the flag refers to can be seen in the event log.

  • Page 45: Alarms

    7.8 Alarms The Prometer 100 is equipped with alarms to be able to indicate when measured quantities are over or under a factory configured limit value. The meter enters the alarm state when the limit value is reached. An alarm is generated only after the alarm state has continued for a configurable time (persistence time).

  • Page 47: Maximum Demand

    The Prometer 100 meter has the capability of logging Maximum Demand for all the selected energy types (except Net Active and Net Reactive). The Maximum Demand is computed for a fixed block of time which is called Demand Integration Period (DIP).

  • Page 48: Historical Registers

    7.10 Historical registers Historical registers are used by the Prometer 100 to store current register values at defined points so as to be able to read them later. Stored in historical registers are all maximum demand values, TOU registers and energy registers, with the exception of energy registers by phase.

  • Page 49: Day Type

    A holiday date specifies the day type that applies on a certain date. Holiday dates can be configured to apply every year on the same date or for a single year. In the Prometer 100, up to 30 holiday dates can be configured.

  • Page 50: Cumulative Maximum Demand Registers

    7.13 Meter Reading The Prometer 100 uses DLMS for meter reading. In DLMS protocol the BCS is considered the client and the meter is the server. On request by the BCS, the meter will send all its supported OBIS codes and expected queries.

  • Page 51: Instrument Transformer Compensations

    The states shorter than three seconds are registered by accumulating registers. If the states last longer than three seconds, they are instead registered in the event log with time stamp and duration. The accumulating counters and the event log can be read in M-Cubed.
