How to check that the solenoid valve opening and closing system operates correctly very simply with a Qualistar+ by analysing the electrical signal controlling the pneumatic system
Any dysfunction on a production line may cause a costly breakdown. This case study presents the case of a bottling plant suffering from intermittent production shutdowns.
File servers, application servers or simple databases: data centres need to ensure high electrical system availability. This case study presents the measurements required to choose the best solution to avoid any power supply outages.
To solve problems due to power overruns and enable customers to achieve substantial savings, Chauvin Arnoux and Enerdis explain the different steps to follow: measurement, analysis and implementation of the solution.
What are harmonics and what causes them? How can they be qualified and represented? What are the consequences for the electrical installation, the equipment, etc.?
Instantaneous power, average power, active power, reactive power, apparent power, power factor, etc. We provide a few reminders concerning these parameters which are fundamental in electronics, as well as the methods for measuring them in three-phase systems.
A measurement campaign may be totally erroneous and useless if the measurements are not performed correctly. One of the main sources of errors is incorrect wiring.
