About me

Not by chance, but a deliberate choice.

I am Steven van der Meijden — founder of Nexums. This is why I do this, what I have experienced and what I believe in.

My story

How Nexums came about.

Nexums grew from an observation I kept seeing in the market: high-voltage connections — clamps, busbar joints, flexible conductors and interfaces — are often the weakest link in an installation that has otherwise been calculated down to the last detail. Knowledge about precisely these components is remarkably fragmented in the Netherlands. I want to change that.

My path there is not by chance, but it is unusual. I graduated as an Aerospace Engineer in Delft, with a strong interest in sustainable energy. My graduation research was at DENS, on a formic acid generator that produces electricity via hydrogen — engineering at the intersection of structure, safety and energy.

After graduating I joined SPIE as a Primary Engineer in high-voltage technology. To truly understand the market, I deliberately stepped sideways to SBI Connectors — part of the SICAME Group, a world leader in connection technology and regular supplier to, among others, TenneT. There I worked as Sales and Account Manager and saw connection technology from a completely different angle: not the calculations, but the practical reality of suppliers, asset owners and the decisions actually made in the field.

That period confirmed two things. First: my heart is in engineering. Second, and this is the core of Nexums: by bringing together technology, market and product, an independent insight emerges that barely exists in this niche. I do not assess a clamp from a single interest — I look at the integrity of the connection itself, verified against IEC 60865, IEC 61284 and IEC 62271.

That is what Nexums offers: an independent, standards-driven perspective on the most underestimated component of your high-voltage installation.

Beliefs

What I believe in.

Safety is not a variable.

A high-voltage connection must never be the weakest point. Safety is not an afterthought in a design, but its starting point.

Reliability is determined at the connection.

The Dutch grid is among the most reliable in the world. That achievement stands or falls with the integrity of every clamp, busbar joint and interface.

The underestimated component deserves the most attention.

Installations are calculated in detail, while the connection often stays out of the picture. I bring that link back into the design and management process.

Approach

How I work.

01

Advisory & connection selection

I advise on the right type of connection for your situation — taking into account load, environment and standards.

02

Collaboration with engineering

I work closely with internal and external engineering teams to integrate connection details into design, revision and execution.

03

Second opinion

When there is doubt about an existing design or execution, I provide an independent technical assessment — substantiated and verifiable.

04

Technical documentation

I prepare assembly specifications, inspection reports and connection drawings that comply with applicable standards (IEC, national standards, grid operator requirements).

05

Inspection & diagnosis

On-site I assess the condition of connections through visual inspection and measurement data — and report clearly on risks and priorities.

06

Knowledge transfer

Through guidance on the shop floor or targeted sessions, I transfer knowledge to your team — so that quality is also assured internally.
