Amsterdam Airport Schiphol operates as a self-contained city where 24/7 continuity is required. With millions of passengers and complex security equipment, downtime due to Power Quality problems is not an option. HyTEPS guarantees the technical reliability of vital security lanes.
Schiphol's electrical infrastructure is immense, with an annual consumption of 200 million kWh and a diversity of users comparable to a medium-sized city. However, the biggest technical challenge is in the security lanes. This is where hundreds of sophisticated scanners and detection gates converge. Although individual devices comply with CE standards, the convergence of all these non-linear loads creates a complex Power Quality issue. Installation managers faced inexplicable risks: from accelerated ageing of expensive equipment to unwanted tripping of circuit breakers.
For an airport of this calibre, uncertainty about the availability of security gates is unacceptable. An outage immediately leads to queues, delays and reputational damage. The fear of failure due to invisible EMC contamination was real. As Ton Baltus, Installation Manager at Schiphol, outlines the urgency:
"When large numbers of passengers have to pass through security lanes on their way to their destination, we really can't afford outages and delays!"
To identify the exact cause of the disruptions, HyTEPS initiated an in-depth measurement process in collaboration with Deerns, Engie and Scarabee. Our analysis of the current and voltage quality showed that harmonic currents were accumulating in the neutral conductor. This phenomenon posed a direct threat to fire safety and the continuity of the installation.
Manager of Technical Engineering Christan van Dorst confirmed through simulations that the three-phase circuit had become unbalanced due to the protection devices. The data showed conclusively: without intervention, these EMC risks led to unavoidable hardware damage and failure. We based the solution not on assumptions, but on hard measured data.
Our engineers implemented seven Active Harmonic Filters (AHF) on the distributors feeding the security lanes. These filters continuously measure contamination and directly inject a counter current to neutralise harmonics. Despite the 24/7 operation at the airport, we planned the installation so that passenger flows were not hindered for a moment.
The result is a stable installation with drastically reduced harmonic load (THD). The sine wave has been restored and zero currents have been reduced to safe levels. In doing so, we have removed uncertainty and ensured long-term security of supply for Schiphol Airport.
Power quality problems are complex, but the solution does not have to be. HyTEPS takes responsibility from measurement to solution. Prevent risks in your critical processes.
