Data governance with Carbon Desktop: Missing readings
We're taking a look at data governance with a series of articles which give you practical information and helpful case studies so you can put good governance of data into practice.
Here we take a look at missing readings - why they are important and how to quantify them.
Why do missing readings matter?
Our recent article about missing readings highlighted the disadvantages of missing readings including:
1. Inaccurate energy insights
2. Delayed problem detection
3. Increased costs
4. Compliance risks
The good news is that using Carbon Desktop's scheduled missing reading report, you will have a quantified and detailed view of missing readings which can be quickly addressed. An example of the output is below:
Here are some examples of how this information might be used to make savings and you can also visit the full article on the Carbon Desktop website here.
Case study 1: Transformer dropout
From 16th April on this graph, the readings trend had missing readings which lead to incorrect reporting and trend analysis.
Fortunately, the missing readings report and trend markers (white triangles), flagged the issue. Site were able to filter the report via data provider to see that it was a low battery in a transmitter which could be easily replaced.
Case study 2: Summary of data providers
For sites with multiple data collection systems and providers, it's helpful to cluster meter dropouts into categories. This allows you to understand and pinpoint which system has data quality issues rather than which meters. A typical report would show meter by meter what the expected readings are and how many are missing as a percentage - so identifying where focus should be directed.
Case study 3: Not fully monitoring system
Originally the site thought that their air compressor system didn't run during weekends and evenings and that the purple compressor on the graph lead most of the consumption.
A missing readings report and markers indicated that the trend they were seeing didn't fully capture the true operation of the unit. A metering fault on the lead VSD (marked in green) was resolved and the site was able to see the air compressor system was running 24/7.
