Data logging

The meter has a default, comprehensive data-logging configuration. Information regarding the default logging capacity and default logging configuration can be found in Default logging capacity.

To learn more about the Data Recorder modules in your meter, refer to the ION Reference.

Configuring data logging

Use Power Monitoring Expert or ION Setup to change your meter’s logging settings.

Using the front panel

You cannot configure logging using the front panel.

Using ION Setup

1. Open the Setup Assistant for your meter. See the ION Setup Help for instructions.
2. Select the Logging folder.

   Use the Memory, Load Profile, and Event Log screens to configure your logging settings.

Memory screen

1. Click Logging > Memory to re-allocate meter memory.
2. Select the log you want to configure and click Edit. You can change both the Log Duration (days) and the Log Size (records). Changing these parameters affects the meter memory allocated to that log.

Load Profile screen

1. Click Logging > Load Profile to configure the Revenue Log.
2. Click the Channels tab to access the Revenue Log sources. Select a source.
   • Click Unlink to unlink the parameter from the source.
   • Click Edit to edit the parameter. The Parameter Selection dialog box displays the source register groupings. To view the individual registers, expand the node beside the register group . Select the register that you want to connect to the source, and then click OK.

     Select the Show all available registers check box for a complete list of all possible registers.

3. Click the Interval/Depth tab to edit the Revenue Log interval and duration and missing record handling.

Events screen

1. Select the Event Log screen to configure what events are logged and the notification settings
2. Click the Events tab, select a parameter and click Edit:

   – Depth: This parameter sets the number of events the event log contains.

– Cutoff: This parameter determines the minimum priority level for events to be logged; events with a lower priority are not logged.

– EvPriority: This parameter sets the event priority of Sag/Swell events. See Configuring power quality event logging for more information.

– PhaseLossEnable: This parameter enables or disables phase loss event recording.

3. Click the Notifications tab to configure the event log notification settings based on the number of unread entries. These settings allow you to define the designated reader and set a limit to the number of unread event log entries. Select a parameter and click Edit to change.
   • Designated Reader: This parameter allows you to select a user to be the designated reader of the event log. An entry in the event log is designated unread until reviewed or backed up to external storage by the designated reader. This feature can assist in ensuring that event log entries are not overwritten before they can be reviewed.
   • SMTP Server: This parameter displays the IP address of the SMTP Server. The value can only be displayed under this tab. Navigate to Communications > Advanced Ethernet > SMTP to change this setting. See Configuring Ethernet connections for information on configuring network settings.
   • Depth: This parameter displays the number of events the event log can contain. The value can only be displayed under this tab. Navigate to Logging > Event Log > Events to change this setting.
   • Unread Events: This parameter displays the number of event log entries that have not been reviewed or backed up to external storage by the designated reader. When the designated reader reviews the event log, this value returns to zero. If any user other than the designated reader reviews the event log, the unread events value does not change. This value is not configurable.

Changing waveform recording

The Waveform Recorder modules do not require changes to their default settings. If you want to change the format of the recorded waveforms, refer to the Waveform Recorder module description in the ION Reference.

NOTE: If you are generating COMTRADE waveform data records, the associated Waveform Recorder modules cannot be modified unless the COMTRADE module’s Module Enable register is set to DISABLED. If the Waveform Recorder modules are not configured identically (have the same setup register values) the COMTRADE module will not go online.

The default logging framework

The following sections outline the default logging capacity and configuration.

NOTE: The default logging configuration may be used by other components of your power monitoring system (for example, the reporting components of Power Monitoring Expert). Before you change the default configuration of any of the logs, ensure you understand the impact on the change on these components and the data they display.

Changing the log depths

Change the value in a Data Recorder module’s Depth setup register to increase the number of records stored in the recorder.

The RecordMode setup register controls how the Data Recorder overwrites old records; refer to the Data Recorder module description in the ION Reference before changing this setup register.

Logging frequency

The five Periodic Timer modules that control the frequency of different data recording are as follows:

• “Revenue Log Trg” controls the frequency of the logging of revenue values
• “Loss Log Trg” controls the frequency of Loss Compensation Data logging
• “EgyDmd Log Trg” controls the frequency of logging for the Energy and Demand Log (this log is used for generating reports using Web Reporter)
• “Hist Log Trg” controls the frequency of Historic Data logging
• “Harm Log Trg” controls the frequency of Harmonics logging

Programming your meter to write to any data recorder at continuous intervals lower than 60 seconds (heavy logging configuration) can cause loss of data in the event of a power failure.

 

Change the value in the Period setup register to change the frequency of data logging (in seconds). Do not change the Sync Mode setup register.

Default logging configuration

The following sections describe each Data Recorder module and the parameters they log. Your meter may not have all the logs described and the settings may vary depending on the meter, its firmware and its template.

Revenue logging

The Revenue Log is configured for use with UTS MV-90 billing software. The default values logged by the Revenue Log are as follows:

Parameter	Description
kWh del int	Interval kWh delivered
kWh rec int	Interval kWh received
kVARh del int	Interval kVARh delivered
kVARh rec int	Interval kVARh received

Historic data logging

Three data recorders are used to record standard power system quantities, such as phase current, phase voltage and power factor. By default, they log the following output register values:

Hist Mean Log Vll ab mean I avg mean Vll bc mean kW tot mean Vll ca mean kVAR tot mean Vll avg mean kVA tot mean V unbal mean PF lag mean Ia mean PF lead mean Ib mean Freq mean Ic mean

Hist High Log Vll ab high I avg high Vll bc high kW tot high Vll ca high kVAR tot high Vll avg high kVA tot high V unbal high PF lag high Ia high PF lead high Ib high Freq high Ic high

Hist Low Log Vll ab low I avg low Vll bc low kW tot low Vll ca low kVAR tot low Vll avg low kVA tot low V unbal low PF lag low Ia low PF lead low Ib low Freq low Ic low

Loss Log

One Loss Log recorder is configured to record loss values. By default, it logs the following parameters – note that the parameters differ depending on the meter template:

Template	Loss Log parameter	Description
All	MU Ia^2h int	Phase A interval current squared hours
All	MU Ib^2h int	Phase B interval current squared hours
All	MU Ic^2h int	Phase C interval current squared hours
35S only	MU Vll ab^2h int	Phase A interval voltage Line-to-Line squared hours
35S only	MU Vll bc^2h int	Phase B interval voltage Line-to-Line squared hours
35S only	MU Vll ca^2h int	Phase C interval voltage Line-to-Line squared hours
9S/29S/36S only	MU Vln a^2h int	Phase A interval voltage Line-to-Neutral squared hours
9S/29S/36S only	MU Vln b^2h int	Phase B interval voltage Line-to-Neutral squared hours
9S/29S/36S only	MU Vln c^2h int	Phase C interval voltage Line-to-Neutral squared hours

Harmonics logging

Two recorders provide various harmonics logs, including K-factor and Total Harmonics Distortion (THD). These recorders are labeled Harm Mean Log and Harm High Log. By default, they log the following values:

Harm Mean log V1 THD mean I1 K Fac mean V2 THD mean I2 K Fac mean V3 THD mean I3 K Fac mean I1 THD mean       I2 THD mean I3 THD mean

Harm High log V1 THD high I1 K Fac high V2 THD high I2 K Fac high V3 THD high I3 K Fac high I1 THD high       I2 THD high I3 THD high

Energy Demand Log

One data recorder is configured to provide power system data for the Web Reporter component of Power Monitoring Expert.

EgyDmd Log
kWh del	kVAh del+rec
kWh rec	kW sd del-rec
kWh del-rec	kVAR sd del-rec
kVARh del	kVA sd del+rec
kVARh rec	PF lag mean
kVARh del-rec	PF lead mean

Sag/Swell and Transient logging

Three data recorders provide details of these power quality events. The Sag/Swell and Transient data recorders, by default, log the following values:

Sag/Swell log (ION8650A and ION8650B)
DistDur	DistV1Engy	DistV2Engy	DistV3Engy
DistV1Min	DistV2Min	DistV3Min	DistNominal
DistV1Max	DistV2Max	DistV3Max	SwellLim
DistV1Avg	DistV2Avg	DistV3Avg	SagLim
Sag/Swell log (ION8650C)
DistDur	DistV2Max	PT Prim

Transient log
TranV1Dur	TranV2Max	TranNominal	PT Sec
TranV1Max	TranV3Dur	Threshold	CT Prim
TranV2Dur	TranV3Max	PT Prim	CT Sec

The SagSwellState data recorder provides additional information required by the Sag/ Swell and Transient logs.

See Configuring power quality event logging for enabling or disabling Sag/Swell and Transient events from being recorded in the Event Log.

NOTE: Modification of the Sag/Swell, Transient and SagSwellState logs is an advanced procedure that should only be performed by experienced users familiar with ION and the interaction of these data recorders.

See the COMTRADE and ION Technology technical note for information about COMTRADE records.

EN50160 compliance logging (ION8650A and ION8650B only)
