Discrimination studies are an essential factor in the design of any electrical installations. Professionals carry out an exhaustive analysis of the electrical protections needed to guarantee the continuity of supply in case of failure. A good discrimination study allows the coordination of different protections at different levels of electrical installations.

The DC module “Direct current” is an additional module of elec calc. It allows the design and sizing of low voltage electrical installations in direct current, up to a voltage of 1500 VDC. Completely integrated into the elec calc software, it maintains all of its functionality and ergonomics and allows the creation of installations mixing DC and AC parts.

The main objective of electrical facilities is to supply reliable power. To guarantee the power supply and the efficient and continuous management of the operations, a highly resistant and secure electrical installation is required. Electrical equipment is potentially hazardous and, in the unfortunate case of failure or anomaly, the consequences can be fatal for both people and properties. This is why it is important to adopt a holistic approach in which personnel, devices, and monitoring systems are integrated.

During these weeks, with the COVID-19 outbreaks, it has been possible to observe how certain facilities (not only hospitals but also hotels, sports centers, libraries …) had to adapt to the emergency state by changing their original design, operation and action protocols, and structural, mechanical, pneumatic and electrical systems. In this following article, we will  focus on these three last topics.
