Electrical power metering for load profiling provides customers with the ability to measure and monitor their power energy needs, taking control of their power usage. However, there are other features such as Event Logs that the power metering should provide to assist with diagnostics of the electrical system.
Event Logs on board power metering will provide assistance to analyse events when they occur. By specifying your power meter to incorporate event logging with date/time stamping, you maintain a practice of event log data for review on past events. By monitoring event logs, you can gain insight into the system behaviour and/or potential changes by users to the power metering set-up.
Event Logs Like Insurance
While a power metering system provides monitoring performance for customers’ load profiling activities, when an event occurs such as loss of power, communication loss, change of unauthorised programming or under/overvoltage occurrence, set parameters will enable traceability. The event log will provide some analysis with sequence of event information to determine potential problems that may have occurred. The power metering system may have a small to large number of power meters deployed with such a network and without any traceability of events it is somewhat difficult to understand issues that may have occurred with the power metering system.
Power Metering Event Logging Software
Typically, power metering event records are shown in the order based on the date and time of the event appearance. The event log usually contains a large amount of records that contain events caused by different sources. You can use filtering to find and work with a subset of events that meet the criteria you specify.
SATEC’s free licensed Power Analysis Software (PAS) can rearrange records from the power meter in order based on the cause of the event, and then sort records within each group according to the event time. The user can change the sorting order on the Event Log and PAS will temporarily hide rows you do not want displayed. You can use a filter along with sorting to rearrange filtered records in the desired order.
System Performance
Using PAS software for monitoring event logs keeps all past logs archived, providing an excellent source of data for analysing system performance and behaviour patterns. Archiving past event logs allows the data for further review and diagnostics of the system where common patterns or vulnerabilities of system reoccur. The same goes for events that are current based on settings such as exceeding demand thresholds and by monitoring event logs in real time, you can detect an issue and prevent it from creating problems.
Other equipment status can be monitored for on/off conditions for pumps, fans, controllers with alarm status digital input with date/time stamping with the power metering with expanded Input/Output modules.
