The first step to do in a process of electrical energy efficiency is to carry out an electrical energy diagnosis and audit. In this process, measurements of power and energy will be taken, as well as other variables necessary for making the suitable decisions.
Along those lines, two key points should be taken into consideration:
- What information do we attempt to get from the measurements?
- Which are the right points to be measured?
In all cases, there are two ways to carry out the audit depending on the installation that is being studied:
Installations that do not have measuring and supervision systems
In this case, measurements must be taken using portable measuring equipment. These equipment permit storing all the variables selected in their memory (power, energy, etc.).
The number of measurements agree with the number of points that are considered to be critical or necessary.
Depending on the type of process, the duration of each measurement will be determined. The aim is to represent the true state of the point measured. The portable equipment permits great fl exibility, but on the other hand, it does not permit the follow up of the energy consumption after the appropriate decisions have been made.
It is recommended to study the points where the measurements are taken for the subsequent installation of a fixed measurement system that communicates with the PowerStudio Scada management software. In this case, the portable measurement equipment is a support equipment used in those places where a fi xed system is not available.
Electrical installations that have PowerStudio management software
In these electrical installations, information can be obtained from the PowerStudio Scada from the data stored in its files.
Then, aside from obtaining information quickly, the critical variables can be followed up.
