Every Monday — an in-depth article on innovation in the areas we work in. Each month has a theme.
Since 2024, data centres with over 500 kW of installed IT power report their energy indicators annually to a European database. What exactly is measured, where the metering points go, and why adding them afterwards is expensive.
ReadUp to 10 kW per rack the question is airflow management. Above 30 kW air physically runs out. And AI workloads now ask for over 100 kW per rack — at which point the conversation moves from air conditioning to pipework.
ReadUPS autonomy is quoted at full load, with a new battery, at 25 °C. None of the three is true on the day the battery is needed. How to calculate the real time to generator pick-up.
ReadTwo supply paths, two UPS systems, two generators — and the whole facility stops on one breaker. How to read a redundancy diagram and where the points hide at which the two paths quietly become one.
ReadAn ordinary inverter follows the grid and stops when it disappears. A grid-forming one creates it. The difference decides whether a battery system is merely a saving on the bill or a standby supply for the whole site — and why that changes the protection.
ReadThe standard that changed how utilities build substations is arriving in the factory transformer station. What it brings, what it demands, and why the interlock between two breakers can now be a message on the network.
ReadA century after the first mechanical breakers, silicon carbide makes something new possible — interrupting a short-circuit current before it ever reaches its peak. What that gives protection, and what is still missing.
ReadThe most common insulating gas in medium-voltage switchgear can no longer be used in new equipment up to 24 kV. What the alternatives are, what they give up, and what the designer of a transformer substation needs to know.
ReadThe next article is published on Monday.
